Cut marks found on Ice Age bones indicate that humans in Ohio hunted or scavenged animal meat earlier than previously known. Dr. Brian Redmond, curator of archaeology at The Cleveland Museum of Natural History, was lead author on research published in the Feb. 22, 2012 online issue of the journal World Archaeology.
Redmond and researchers analyzed 10 animal bones found in 1998 in the collections of the Firelands Historical Society Museum in Norwalk, Ohio. Found by society member and co-author Matthew Burr, the bones were from a Jefferson’s Ground Sloth. This large plant-eating animal became extinct at the end of the Ice Age around 10,000 years ago.
“This research provides the first scientific evidence for hunting or scavenging of Ice Age sloth in North America,” said Redmond. “The significant age of the remains makes them the oldest evidence of prehistoric human activity in Ohio, occurring in the Late Pleistocene period.”
A series of 41 incisions appear on the animal’s left femur. Radiocarbon dating of the femur bone estimates its age to be between 13,435 to 13,738 years old. Microscopic analyses of the cut marks revealed that stone tools made the marks. The pattern and location of the distinct incisions indicate the filleting of leg muscles. No traces of the use of modern, metal cutting tools were found, so the marks are not the result of damage incurred during their unearthing. Instead, the morphology of the marks reveals that they were made by sharp-edged stone flakes or blades.
The “Firelands Ground Sloth,” as the specimen is named, is one of only three specimens of Megalonyx jeffersonii known from Ohio. Based on measurements of the femur, tibia and other bones, it is one of the largest individuals of this species on record. It had an estimated body mass of 1,295 kilograms (2,855 pounds).

First archaeological evidence of Christianity from the time of Jesus
Ω
The archaeological examination by robotic camera of an intact first century tomb in Jerusalem has revealed a set of limestone Jewish ossuaries or "bone boxes" that are engraved with a rare Greek inscription and a unique iconographic image that the scholars involved identify as distinctly Christian.
The four-line Greek inscription on one ossuary refers to God "raising up" someone and a carved image found on an adjacent ossuary shows what appears to be a large fish with a human stick figure in its mouth, interpreted by the excavation team to be an image evoking the biblical story of Jonah.
In the earliest gospel materials the "sign of Jonah," as mentioned by Jesus, has been interpreted as a symbol of his resurrection. Jonah images in later "early" Christian art, such as images found in the Roman catacombs, are the most common motif found on tombs as a symbol of Christian resurrection hope. In contrast, the story of Jonah is not depicted in any first century Jewish art and iconographic images on ossuaries are extremely rare, given the prohibition within Judaism of making images of people or animals.
The tomb in question is dated prior to 70 CE, when ossuary use in Jerusalem ceased due to the Roman destruction of the city. Accordingly, if the markings are Christian as the scholars involved believe, the engravings represent – by several centuries - the earliest archaeological record of Christians ever found. The engravings were most likely made by some of Jesus' earliest followers, within decades of his death. Together, the inscription and the Jonah image testify to early Christian faith in resurrection. The tomb record thus predates the writing of the gospels.
The findings are detailed in a preliminary report by James D. Tabor, professor and chair of religious studies at the University of North Carolina at Charlotte, published online in www.bibleinterp.com.
"If anyone had claimed to find either a statement about resurrection or a Jonah image in a Jewish tomb of this period I would have said impossible -- until now," Tabor said. "Our team was in a kind of ecstatic disbelief, but the evidence was clearly before our eyes, causing us to revise our prior assumptions."
The publication of the academic article is concurrent with the publication of a book by Simon & Schuster entitled "The Jesus Discovery: The New Archaeological Find That Reveals the Birth of Christianity." The book is co-authored by Professor James Tabor and filmmaker/professor Simcha Jacobovici. A documentary on the discovery will be aired by the Discovery Channel in spring 2012.
The findings and their interpretation are likely to be controversial, since most scholars are skeptical of any Christian archaeological remains from so early a period. Adding to the controversy is the tomb's close proximity to a second tomb, discovered in 1980. This tomb, dubbed by some "The Jesus Family Tomb," contained inscribed ossuaries that some scholars associate with Jesus and his family, including one that reads "Jesus, son of Joseph."
"Context is everything in archaeology," Tabor pointed out. "These two tombs, less than 200 feet apart, were part of an ancient estate, likely related to a rich family of the time. We chose to investigate this tomb because of its proximity to the so-called 'Jesus tomb,' not knowing if it would yield anything unusual."
The tomb containing the new discoveries is a modest sized, carefully carved rock cut cave tomb typical of Jerusalem in the period from 20 BCE until 70 CE.
The tomb was exposed in 1981 by builders and is currently several meters under the basement level of a modern condominium building in East Talpiot, a neighborhood of Jerusalem less than two miles south of the Old City. Archaeologists entered the tomb at the time, were able to briefly examine it and its ossuaries, take preliminary photographs, and remove one pot and an ossuary, before they were forced to leave by Orthodox religious groups who oppose excavation of Jewish tombs.
The ossuary taken, that of a child, is now in the Israel State Collection. It is decorated but has no inscriptions. The archaeologists mention "two Greek names" but did not notice either the newly discovered Greek inscription or the Jonah image before they were forced to leave. The tomb was re-sealed and buried beneath the condominium complex on what is now Don Gruner Street in East Talpiot.
The adjacent "Jesus tomb," was uncovered by the same construction company in 1980, just one year earlier. It was thoroughly excavated and its contents removed by the Israel Antiquities Authority. This tomb's controversial ossuaries with their unusual cluster of names (that some have associated with Jesus and his family) are now part of the Israel State Collection and have been on display in various venues, including the Israel Museum. These ossuaries will be in an exhibit running from late February through April 15 at Discovery Times Square.
In 2009 and 2010, Tabor and Rami Arav, professor of archaeology at the University of Nebraska at Omaha, working together with Jacobovici, obtained a license to excavate the current tomb from the Israel Antiquities Authority under the academic sponsorship of the University of North Carolina at Charlotte. Because of its physical location under a modern building (making direct access nearly impossible), along with the threat of Orthodox Jewish groups that would protest any such excavation, Tabor's team determined to employ a minimally invasive procedure in examining the tomb.
Funding for the excavation was provided by the Discovery Channel/Vision Television/Associated Producers. Jacobovici's team at the Toronto based Associated Producers developed a sophisticated robotic arm to carry high definition cameras, donated by General Electric. The robotic arm and a second "snake camera" were inserted through two drill holes in the basement floor of the building above the tomb. The probe was successful and the team was able to reach all the ossuaries and photograph them on all sides, thus revealing the new inscriptions.
Beyond the possible Christian connection, Tabor noted that the tomb's assemblage of ossuaries stands out as clearly extraordinary in the context of other previously explored tombs in Jerusalem.
"Everything in this tomb seems unusual when contrasted with what one normally finds inscribed on ossuaries in Jewish tombs of this period," Tabor said. "Of the seven ossuaries remaining in the tomb, four of them have unusual features."
There are engravings on five of the seven ossuaries: an enigmatic symbol on ossuary 2 (possibly reading Yod Heh Vav Heh or "Yahweh" in stylized letters that can be read as Greek or Hebrew, though the team is uncertain); an inscription reading "MARA" in Greek letters (which Tabor translates as the feminine form of "lord" or "master" in Aramaic) on ossuary 3; an indecipherable word in Greek letters on ossuary 4 (possibly a name beginning with "JO…"); the remarkable four-line Greek inscription on ossuary 5; and finally, and most importantly, a series of images on ossuary 6, including the large image of a fish with a figure seeming to come out of its mouth.
Among the approximately 2000 ossuaries that have been recovered by the Israel Antiquities Authority, only 650 have any inscriptions on them, and none have inscriptions comparable to those on ossuaries 5 and 6.
Less than a dozen ossuaries from the period have epitaphs but, according to Tabor, these inscribed messages usually have to do with warnings not to disturb the bones of the dead. In contrast, the four-line Greek inscription contains some kind of statement of resurrection faith.
Tabor noted that the epitaph's complete and final translation is uncertain. The first three lines are clear, but the last line, consisting of three Greek letters, is less sure, yielding several possible translations: "O Divine Jehovah, raise up, raise up," or "The Divine Jehovah raises up to the Holy Place," or "The Divine Jehovah raises up from [the dead]."
"This inscription has something to do with resurrection of the dead, either of the deceased in the ossuary, or perhaps, given the Jonah image nearby, an expression of faith in Jesus' resurrection," Tabor said.
The ossuary with the image that Tabor and his team understand to be representing Jonah also has other interesting engravings. These also may be connected to resurrection, Tabor notes. On one side is the tail of a fish disappearing off the edge of the box, as if it is diving into the water. There are small fish images around its border on the front facing, and on the other side is the image of a cross-like gate or entrance—which Tabor interprets as the notion of entering the "bars" of death, which are mentioned in the Jonah story in the Bible.
"This Jonah ossuary is most fascinating," Tabor remarked. "It seems to represent a pictorial story with the fish diving under the water on one end, the bars or gates of death, the bones inside, and the image of the great fish spitting out a man representing, based on the words of Jesus, the 'sign of Jonah' – the 'sign' that he would escape the bonds of death."

Tabor comments on the nearby tomb:
In terms of wider archaeological context this present “Patio” tomb is less than 45 meters away from a second tomb discovered a year earlier, in March/April, 1980—the so-called “Jesus family tomb.” This tomb contained ten ossuaries with six of them inscribed with names, five Aramaic and one Greek: Yeshua bar Yehosef, Maria, Yose, Yehuda bar Yeshua, Matya (Aramaic), and Mariamenou Mara or Mariam kai Mara (Greek). The possible connection of this tomb to Jesus of Nazareth and/or his family sparked heated controversy since 2007 when it was first brought to wider public and academic attention.
Other than theological objections, the response most often offered to any probable identification of this tomb with Jesus and his family is that “the names are common.” Subsequent research has definitely shown that is not the case, either from a statistical standpoint or even a practical observation—though one hears it endless repeated even from academics who should know better.There is not a single cluster of names ever found in any tomb in Jerusalem from this period, other than this one, out of the estimated 900 that have been exposed, that one could plausibility even make the argument of correspondence with Jesus and names associated with his family. This does not prove the tomb is that of Jesus of Nazareth and his family but it does demonstrate that its probability should not be dismissed...
If, the burial of Jesus, as all our ancient sources report, was carried out by a wealthy and influential member of the Sanhedrin, namely Joseph of Arimathea, who had the backing of the Roman governor Pontius Pilate, might we expect any “Jesus family tomb” to be on his property and thus adjacent to other tombs that belonged to his extended clan.
The gospel of John indicates that the initial burial of Jesus near the place of crucifixion was a hasty emergency measure in the late afternoon prompted by the nearness of the Sabbath/Passover holiday at sundown on the day of Jesus’ crucifixion (John 19:41-42). It was a burial of necessity and opportunity. This particular tomb was chosen because it was unused and happened to be near the place of crucifixion.
The idea that this tomb belonged to Joseph of Arimathea makes no sense. What are the chances that Joseph of Arimathea would just happen to have his own new family tomb conveniently located near the Place of the Skull, or Golgotha, where the Romans regularly crucified their victims? Amos Kloner offers the following analysis, with which I wholly agree:I would go one step further and suggest that Jesus’ tomb was what the sages refer to as a “borrowed (or temporary) tomb.” During the Second Temple period and later, Jews often practiced temporary burial. . . A borrowed or temporary cave was used for a limited time, and the occupation of the cave by the corpse conferred no rights of ownership upon the family. . . Jesus’ interment was probably of this nature.
Mark indicates that the intention of Joseph was to complete the full and proper rites of Jewish burial after Passover. One would assume a more permanent burial cave would have been provided for Jesus as soon as the Passover was over and burial rites could be completed.

European Neanderthals Were On the Verge of Extinction Even Before the Arrival of Modern Humans
Ω
New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised.
This new perspective on the Neanderthals comes from a study of ancient DNA published February 25 in Molecular Biology and Evolution.
The results indicate that most Neanderthals in Europe died off as early as 50,000 years ago. After that, a small group of Neanderthals recolonised central and western Europe, where they survived for another 10,000 years before modern humans entered the picture.
The study is the result of an international project led by Swedish and Spanish researchers in Uppsala, Stockholm and Madrid.
“The fact that Neanderthals in Europe were nearly extinct, but then recovered, and that all this took place long before they came into contact with modern humans came as a complete surprise to us. This indicates that the Neanderthals may have been more sensitive to the dramatic climate changes that took place in the last Ice Age than was previously thought”, says Love Dalén, associate professor at the Swedish Museum of Natural History in Stockholm.
In connection with work on DNA from Neanderthal fossils in Northern Spain, the researchers noted that the genetic variation among European Neanderthals was extremely limited during the last ten thousand years before the Neanderthals disappeared.
Older European Neanderthal fossils, as well as fossils from Asia, had much greater genetic variation, on par with the amount of variation that might be expected from a species that had been abundant in an area for a long period of time. “The amount of genetic variation in geologically older Neanderthals as well as in Asian Neanderthals was just as great as in modern humans as a species, whereas the variation among later European Neanderthals was not even as high as that of modern humans in Iceland”, says Anders Götherström, associate professor at Uppsala University.
The results presented in the study are based entirely on severely degraded DNA, and the analyses have therefore required both advanced laboratory and computational methods. The research team has involved experts from a number of countries, including statisticians, experts on modern DNA sequencing and paleoanthropologists from Denmark, Spain and the US.
Only when all members of the international research team had reviewed the findings could they feel certain that the available genetic data actually reveals an important and previously unknown part of Neanderthal history. “This type of interdisciplinary study is extremely valuable in advancing research about our evolutionary history. DNA from prehistoric people has led to a number of unexpected findings in recent years, and it will be really exciting to see what further discoveries are made in the coming years”, says Juan Luis Arsuaga, professor of human paleontology at the Universidad Complutense of Madrid.

Maya Civilization Collapse Related to Modest Rainfall Reductions
Ω
A new study reports that the disintegration of the Maya Civilization may have been related to relatively modest reductions in rainfall.
This is a temple in the Kingdom of Tikal, one of the most prominent of the Classic Period. (Credit: Professor Medina-Elizalde)
The study was led by Professors Martín Medina-Elizalde of the Yucatan Center for Scientific Research in Mexico and Eelco Rohling of the University of Southampton in the UK. Professor Rohling says: "Our results show rather modest rainfall reductions between times when the Classic Maya Civilization flourished and its collapse -- between AD 800-950. These reductions amount to only 25 to 40 per cent in annual rainfall. But they were large enough for evaporation to become dominant over rainfall, and open water availability was rapidly reduced. The data suggest that the main cause was a decrease in summer storm activity."
The study combines records of past climate changes from stalagmites and shallow lakes to model 40 per cent reductions in summer rainfall and reduced tropical storm activity over the region. The work is published in the leading scientific journal Science.
Professor Medina-Elizalde, who led the study while at the National Oceanography Centre in Southampton working with Professor Eelco Rohling, says: "For more than a century, researchers have related the demise of the Classic Maya civilization to climate change, and especially to drought. No sound estimates had been made about the severity of this drought, but some have suggested extreme scenarios. New data made it possible to finally get detailed estimates. To do this, we developed a model that coherently explains changes in critical datasets of change in the region's balance between evaporation and rainfall."
Professor Rohling explains why such modest rainfall reductions would cause the disintegration of a well-established civilisation: "Summer was the main season for cultivation and replenishment of Mayan freshwater storage systems and there are no rivers in the Yucatan lowlands. Societal disruptions and abandonment of cities are likely consequences of critical water shortages, especially because there seems to have been a rapid repetition of multi-year droughts."
The scientists also note that the reconstructed droughts during the demise of the Classic Maya Civilization were of similar severity as those projected by the IPCC for the near future in the same region. Professor Medina-Elizalde adds:
"There are differences too, but the warning is clear. What seems like a minor reduction in water availability may lead to important, long-lasting problems. This problem is not unique to the Yucatan Peninsula, but applies to all regions in similar settings where evaporation is high. Today, we have the benefit of awareness, and we should act accordingly."

Archaeologists Excavate A City of the Decapolis
Ω
Complete article
Archaeologists and students are excavating a rich motherlode of well-preserved remains at the site of the monumental city of Hippos, devastated by a massive eighth century C.E. earthquake that made it all possible.
A line of fallen ancient columns remain in place today, undisturbed, configured exactly where they fell after a massive, devastating earthquake destroyed this city on January 18th, 749 C.E. They appear as though the event had happened only yesterday.
Known as Antiochia Hippos (Hippos meaning "horse", or Hebrew Sussita, also meaning "horse"), its ruins are perched atop Sussita Mountain, an isolated table-top mountain that overlooks the eastern bank of Lake Kinneret (the Sea of Galilee) in present-day Israel. Established initially by the Seleucids as a Greco-Roman enclave, it once controlled two port facilities on the lake and its surrounding countryside. Hippos was part of the "Decapolis", a group of ten cities in Roman Palestine that were maintained as Greco-Roman cultural islands in the Near East. The damage the earthquake caused Hippos was so severe that its citizens abandoned it, never to return again. This left it to the ages with no succeeding settlement and, coupled with its relative isolation and enduring basaltic construction, preserved it much like it was left in the 8th century for 20th century archaeologists to explore. Since the year 2000, a team of archaeologists, specialists, students and volunteers under Professor Arthur Segal and Dr. Michael Eisenberg of the Zinman Institute of Archaeology, University of Haifa, have been excavating the site.

Since the year 2000, a team of archaeologists, specialists, students and volunteers under Professor Arthur Segal and Dr. Michael Eisenberg of the Zinman Institute of Archaeology, University of Haifa, have been excavating the site.
Aelia Capitolina - Roman Jerusalem

Aelia Capitolina has sprung to life in a significant way through no less than four extensive excavations that have taken place in the Old City area, and in a number of other digs in other parts of Jerusalem. Most of these digs have been rescue excavations by the Antiquities Authority, salvage digs carried out before new construction and development goes ahead. In a few more years, Aelia Capitolina could again be covered over by new buildings.
In the rear section of the Western Wall plaza, in the spot where the Western Wall Heritage Foundation intends to erect a large building that it calls "the Core House," Antiquities Authority researcher Shlomit Wexler-Bedolah discovered an ornate and broad Roman street, complete with shops on each side. This is the eastern cardo, along whose path Hagai Street would later be paved.
Three hundred meters to the south, another Antiquities Authority researcher, Dr. Doron Ben-Ami, discovered the place where the Roman street apparently ended. The corner of the street is adjacent to the Givati parking lot at the top of the Silwan valley - the spot where the Elad organization intends to build a large visitors center. In a large rescue excavation at this location in recent years, Ben-Ami exposed a large, fancy Roman villa unlike any other structure from its time in the entire country. He estimates that the villa he uncovered was the home of the regional governor or some other central authority.
In another excavation, in the tunnel under the Western Wall, Wexler-Bedolah and archaeologist Alexander Onn re-estimated the dating of a large bridge leading to the Temple Mount. As with other ancient monuments this too turned out to be of Roman origin and not from the Second Temple period. Another example is the Roman bathhouse and swimming pool discovered by Sion a year and a half ago. "It's a tremendous spa, a country club," Sion says, comparing the bathhouse to similar facilities found in other parts of the Roman Empire.
This increasing number of Roman-era discoveries strengthens the notion that the Temple Mount, even after its destruction, did not lie totally barren, but was used for pagan worship rites.
But not only the Old City and its immediate surroundings have turned up new findings from Aelia Capitolina. Excavations made a few years ago in the area near the Binyanei Ha'uma international convention center, carried out in preparation for the expansion of the Crowne Plaza Hotel, uncovered a large pottery-workers village that served as the legion's central clayware manufacturing plant. Along the route of Jerusalem's new light-rail, remains of a large water facility serving the legionnaires were discovered, and in the area of Shuafat, a Jewish settlement from the same period was discovered.
The latest excavations give archaeologists much greater insight into Aelia Capitolina than was possible even a decade earlier. Experts agree the city was planned extraordinarily well, based as it was on designs of other cities in the empire and according to orders that came directly from the emperor. It included broad streets, numerous and magnificent entrance gates, temples and infrastructure, and it even housed a new elite of army officers and free soldiers who turned Aelia Capitolina into a thriving city.
"When I began to study the history of the Roman city, it was a barren field," says Prof. Yoram Zafrir, one of Israel's most veteran archaeologists. "Today, it is clear that the basic structure of Jerusalem is that of Aelia Capitolina." Zafrir describes the process by which, after the Roman period, beasts of burden replaced wagons, the central government became weak and streets became "privatized." This process led to the city that we know today.

Jerusalem dig uncovers earliest evidence of local cultivation of etrogs
Complete article
The earliest evidence of local cultivation of three of the Sukkot holiday's traditional "four species" has been found at the most ancient royal royal garden ever discovered in Israel.
The garden, at Kibbutz Ramat Rachel in Jerusalem, gave up its secrets through remnants of pollen found in the plaster of its walls.
The garden was part of an Israelite palace at Ramat Rachel that has been excavated for many years, most recently in a joint dig by Prof. Oded Lipschits and Dr. Yuval Gadot of Tel Aviv University and Prof. Manfred Oeming of Heidelberg University. The palace existed from the time of King Hezekiah until the Hasmonean period in the second century B.C.E....
The find that most excited the scholars was pollen from etrogs, or citrons, a fruit that originated in India. This is the earliest botanical evidence of citrons in the country.
Scholars believe the citron came here via Persia, and that its Hebrew name, etrog, preserves the Persian name for the fruit - turung. They also say royal cultivation of the exotic newcomer was a means of advertising the king's power and capabilities.
The garden at Ramat Rachel is also the first place in the country to yield evidence of the cultivation of myrtle and willow - two more of the four species used in Sukkot rituals.
