Particularly the little geometric signs, the dots, the lines, the triangles, the circles, these things are so often overlooked by all those flashy mammoths and bison that are floating around on the walls.
Then, between 15,000 and 5,000 years ago, likely because of a changing climate, hunting by humans, and competition with bison, horses disappeared from the American archaeological record.
In more fertile spots the observer would have come to the conclusion that one of those great herds of bisons which graze upon the prairie land was approaching him.
As ruminants with multi-chambered stomachs, bison can extract more nutrients from grass and this may help explain why they survived when other grazers such as the wild horses did not.
