Titanoides
Titanoides is an extinct genus of pantodont mammal that lived in North Dakota and as far north as central Alberta. They were up to  long and up to  in weight, being the largest mammals of their habitat, a tropical swampland where the main predators were crocodiles. They had a bear-like appearance with huge canines, short limbs and five clawed digits; however, they were herbivores and probably had traits and attributes more similar to diprotodontids. References
