This picture is good because it shows how big these animals are compared to the modern buffalo we know today and a human. The ancient bison is the one second from the left, with the big camel hump on its back. They are also 1 3/4 Tons in weight which is a GIANT animal!
The bison Latifrons is very cool too, I like how big the horns are this one they are probably the size of some small elephants!! Read the wikipedia because they have a lot of differences between modern buffalo and bison. I found the image when I googled the scientific name bison antiquus on google image search.
