Archaeologists have spent a lot of time analyzing the flashiest objects recovered at ancient sites.

But now they're giving a second look at the waste and finding that it too tells tales about a culture.

For example, 8,000-year-old poop recently revealed parasitic infections among people who lived in settlements versus their hunter-gatherer counterparts.

And now, archaeologists have examined another overlooked artifact, small stone flakes, typically thought to be byproducts from the production of tools like hand axes and clevers.

It was not easy to convince the scientific community that there is value to study these items

because they were regarded just as whites.

Ron Barcai, an archaeologist at Tel Aviv University.

His team studied 283 stone flakes found in Israel at a site inhabited by our Homo erectus

relatives half a million years ago.

They found evidence of use, like small fractures along the edges of the inch-long flakes,

but they also discovered bits of bone and flesh, still sticking to the tiny blades,

flesh that could have come from elephants.

The big mammals were much more widespread back then, and were a prominent source of protein for early humans in that area.

The team then tested replicas of the flakes to butcher wild boars and deer and sheep,

and they concluded that such tools would have been really useful to ancient hunters,

for skinning hides, filleting meat, and scraping every bit of nutrition out of an animal.
