New study finds ancient humans butchered elephants with stone tools 500,000 years ago
Archaeologists working at a site in Israel have found stone tools made hundreds of thousands of years ago alongside the remains of an ancient species of elephant and other game. The researchers tested the stone tools scientifically and found residue of fat and bone on them. They speculate Homo erectus people used the tools to butcher elephants and other animals for eating.
The authors, in their article in the journal PLOS One , say the site is just one of many Paleolithic sites showing evidence that people in the distant past butchered and ate elephants and mammoths. The site examined in this study was of Acheulian culture and dates between 300,000 and 500,000 years before the present. Homo erectus was a pre- Homo sapiens species that is considered not to have been as advanced as modern humans, but recent studies have shown they were more advanced than initially believed.

But did these people who lived so long ago hunt or scavenge the elephants? In their article the authors allude to this question but don’t speculate about it.
“The methods of obtaining meat by early humans [are] still under discussion. While some scholars still argue that in Palaeolithic times humans were scavengers, most researchers nowadays strongly advocate hunting as the principal method for obtaining calories, based on new results of sets of analyses of the archaeological record. In this paper, however, we make no contribution regarding this hunting-scavenging debate but focus our attention on the use of Palaeolithic stone tools that follows the acquisition of the carcasses,” they wrote.
However Paleolithic people obtained the elephant carcasses for meat and marrow. The article says elephant and mammoth bones with cut marks indicating meat removal and percussion marks indicating marrow extraction are found at many Paleolithic sites.

“The archaeological record indicates that elephants must have played a significant role in early human diet and culture during Palaeolithic times in the Old World,” they wrote. “... Elephant remains are found in Palaeolithic sites, both open-air and cave sites, in Europe, Asia, the Levant, and Africa. In some cases elephant and mammoth remains indicate evidence for butchering and marrow extraction performed by humans. Revadim Quarry (Israel) is a Late Acheulian site where elephant remains were found in association with characteristic Lower Palaeolithic flint tools. In this paper we present results regarding the use of Palaeolithic tools in processing animal carcasses and rare identification of fat residue preserved on Lower Palaeolithic tools. … The association of an elephant rib bearing cut marks with these tools may reinforce the view suggesting the use of Palaeolithic stone tools in the consumption of large game.”
The authors said they found thousands of animal bones in each layer of the site, including the ancient elephant species Palaeloxodon antiquus , and oxen, gazelles, deer, and horses. There were 155 bones of the straight-tusk elephant in total.
The tools they examined include a scraper and a hand ax or biface, two tools typical of Paleolithic technology. (See the photos below.)

The scraper in the image below had “an organic residue probably of vegetable nature” and indications that it “had a prolonged contact with animal tissues,” the authors wrote.
The researchers also looked at use wear on these tools and found “well preserved and clear use-wear traces, including both edge removals and polishes. The biface use traces indicate the processing of medium-hard material throughout transversal motions, related probably to hide scraping. In the case of the scraper, the traces shows attributes associated with soft or medium material processed throughout longitudinal motion. The possible interpretation is cutting of animal tissues. Another kind of polish, that could be associated with wood, was also detected.
Both tools shows residue of adipocere (animal fat) which can be related to butchering (de-skinning) activity or hide working. On the scraper, both tissues and vegetable materials residues were found.

George Frison proved that the skin of an elephant can be penetrated and skinned. This man developed the university of wyomings archeological department.. He proved this by butchering and penetrating an elephant with a clovis point styled spear.. I watched this video during one of my archeology classes… http://video.wyomingpbs.org/video/2365325678/
Hi Tom. I am not a scientist at all and cannot speak to dating methods or accuracy. I think the researchers based their dating also in the context of the Acheulian culture, which was a Homo erectus culture of 200,000 to 1.8 million years ago. They mention this time frame in their article. Also, they wrote, “It is also of note here that during the Late Acheulian some significant technological innovation also took place, such as the appearance of prepared core technologies that developed further into the characteristic Levallois technology of the Middle Palaeolithic period.” One could conclude that the technology at Revadim was consistent with this 300,000- to 500,000-year-before-present time frame.
Also, they say the site is “at least” that old, which is an important qualifier for observant people like you.
Thank you for your interest.
A very interesting and important find, but I have a question about the dating. In the Plos One article, they give the cave a date of 500-300 thousand years ago, based on paleomagnetic dating and uranium dating. Both of these dating methods remain seriously open to question. We have something seriously wrong with our theory of the earth's geomagnetism, as scientists have found that the geomagnetic field has decreased over 10% in the last 150 years. No one has an explanation. Some say the earth's poles will switch, but base in only on guessing, no math. In theory, it should never change, because the current theory says the rotation of the earth as it orbits through the sun's field causes ours. So the theory has problems. And uranium dating also has massive problems, because it depends completely on the accuracy of the guesstimate of the initial deposit of uranium in water in the rocks of the cave, a very complex process subject to giant errors. This will always remain the case. Dating the near past has errors and dating the far past giant errors, or just guesstimates.
