Bison latifrons (Long-horned Bison)

[RSN]

Long-horned Bison
Bison latifrons



Had horns measuring nine feet from tip to tip (1,8 m). Extinct about 20.000 years ago during the Pleistocene, in North America. Not much larger than it living relatives, they lived in groups, smaller than those of the living bison, moving from a place to another in a determined part of the year. A few specimens as been found in Rancho De La Brea.

It's the first time I see a bison with horizontal horns like these. Its horns, with their angle, look like those of an Indian Buffalo.

An interesting article on the occurrence of Bison latifrons in North Dakota:

The skeletons of this animals are really intersting, because their elongated back-spines are nearly identical to those of Spinosaurus, what shows that it is very probable that they had a similar function (and that Spinosaurus had no "sail" at all, but that the spines were covered with muscles). Just look at the skeleton to see the huge vertebra-spines: www.tarpits.org/education/guide/art/page13e.jpg

Sordes, I think that the bison skeleton you have posted belongs to Bison antiquus, another species, short-horned and with that huge hump over the elongated vertebra-spines:

Oh, sorry, your´re right.
