Taxonomy

Megatylopus was named by Matthew and Cook (1909). Its type is Megatylopus gigas. It was synonymized subjectively with Paracamelus by Macdonald (1959). It was assigned to Camelidae by Matthew and Cook (1909), Webb (1965), Patton (1969), Harrison (1985), Carroll (1988) and Honey et al. (1998).[2][3][4][5][6]

Morphology

Restoration

It stood about 4,20 m (14 ft) tall, with its legs already measuring 2,10 m (7 ft). Fossil remains have been found in Oklahoma, USA.

Body mass

A single specimen was examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. This specimen was estimated to weigh 1,698.4 kg (3,700 lb) [7]

Fossil distribution

Fossil distribution ranged from North Carolina to California.
