And what sort of evidence are you finding in these, in these ancient river sediments?

Well, we're getting pollen from these fine grain sediments.

We're getting wood.

We're getting other plant remains, little seeds.

[swallows] Uh, also getting beetles, and they're very good for reconstructing climate, and on top of that, we're getting animal re- remains, animal bones, um, and teeth, and they really help with the dating of the site.

There are finds suggesting humans could have lived here then too.

Actually today we recovered one of the rare artifacts that we're also getting from the site, and this is really exciting 'cause it shows that humans were living here at that time.

This is just coming out today.

This is a small flake, it's slightly broken but you can see all the tell signs of human manufacture.

And amongst them are even some intact stone tools.

this we actually nicknamed the this the butter knife because it's so pretty but you can see all the evidence of human working there that bulb with percussion rings coming out from that characteristic rippling and actually on this piece they've um modified that edge it would certainly be ideal as some sort of you know for cutting meat
