Titanoides

Titanoides is an extinct genus of pantodont mammal that lived in North Dakota. They were up to 3 m (9.8 ft) long and up to 150 kg (330 lb) 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 and short limbs with five clawed digits even though they were herbivores.
