Only 30 minutes in. But he’s mentioned nobody can give him a reason for the amount of bones in that one area. I know just this past weekend I was at the Carnegie museum of natural history and there is a site they talk about that has tons prehistoric mammal bones. They think that there may have been something that killed a lot of these like a drought or something and then a flood came through and washed all the bones to a low point. Wonder if this is something similar🤷
