There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

I believe "tyrant sea bear" is referring to U. m. tyrannus as that is what the scientific name translates to. So refer back to a few posts ago for the estimates on size of the ulna. As a whole, ecosystem productivity (energy yield of the ecosystem) was much greater in the Pleistocene, thus plant mass was greater, leading to greater herbivore mass, which led to greater carnivore mass and allowed omnivores (i.e. the short faced bears) to become out of the world giants.
