As found in a 2010 study by Soibelzon and Borja Figueirido, the skull and jaws of A. angustidens wer most similar to those of omnivorous species like the sun bear, the Asian black bear, and the North American “short-faced” bear Arctodus simus, another prehistoric species thought to have been extremely predatory but recently reconstructed as an omnivore.

The South American giant short-faced bear (Arctotherium angustidens Gervais and Ameghino, 1880) is one of five described Arctotherium species endemic to South America and it is known for being the earliest, largest, and most carnivorous member of the genus. In a photo included in a National Geographic News report, Soibelzon holds up the humerus - upper arm bone - of the bear next to that of an elephant, and the two are nearly equal in size. We suggest that the larger size and more carnivorous nature of A. angustidens, compared to later members of the genus, may reflect the relative lack of other large carnivores and abundance of herbivores in South America just after the Great American Biotic Interchange.
