Temporal range: middle to late Miocene
|Mummified Procamelus head.|
Procamelus was named by Leidy (1858). It is not extant. It was assigned to Camelidae by Leidy (1858) and Carroll (1988). The name is derived from the Greek πρό, meaning "before" or denoting priority of order, and κάμελος ("camel"), thus "fore-camel", "early camel" or "predecessor camel".
It had long legs designed for speed, and was about 1.3 metres (4.3 ft) in height at the shoulder, slightly smaller than a modern llama. Unlike modern camelids, it had a pair of small incisor teeth in the upper jaw. The remaining teeth were large and adapted for eating tough vegetation. The shape of the toes suggests that it possessed foot pads, like modern camels, unlike earlier forms of camelid, which generally had hooves. This would have helped it walk over relatively soft ground.
A single specimen was examined for estimated body mass by M. Mendoza, C. M. Janis, and P. Palmqvist. This specimen was estimated to weigh 53.3 kg (120 lb). It had a straighter neck than Oxydactylus or Aepycamelus.
