Taxonomy

Paratylopus Paratylopus was named by Matthew (1909) [named as subgenus by Matthew 1904; raised to genus level]. It was assigned to Camelidae by Matthew (1909) and Carroll (1988).[2][3]

Morphology

Four specimens were examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. These specimens were estimated to weigh:

Fossil distribution

Fossil distribution is centered in western Wyoming, eastern Nebraska to northeastern Colorado to southwestern South Dakota.
