Alforjas is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America during the Miocene through Pliocene 10.30—5.3 mya existing for approximately 5 million years.[2]

Taxonomy[edit]

Alforjas was named by Harrison (1979). Its type is Alforjas taylori. It was assigned to Camelidae by Harrison (1979) and Carroll (1988).[3] They are most closely related to Camelops.

Etymology[edit]

Alfrojas is Spanish for the saddle bags used on domestic llamas. The name has a regional association with the meaning of humps or lumps. [1]

Morphology[edit]

A single specimen was examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. The specimen was estimated to weigh 623.3 kg (1,400 lb).[4]

Alforjas differs from Pliauchenia, Hemiauchenia, Palaeolama, and Lama in its greater height of crown, larger size, and longer rostrum.[1]
