Uintathere studies

I never seen this tertiary mammal before...It looks like some sortof rhino and hippo mix with sbaer teeth. I wonder what time it lived in and perhaps you could tell me. Anyway, very good anatomy and colurs for it, but there is one thing I really can't get out of my head at this moment, and it's something to do with the largest monstrosity of the Cretaceous seas, hmmm...Oh well, I guess I woudln't be able ot do this in a million years XD lol. Very good, I am so tempted to fav, it looks that good.
