Paracamelus is an extinct genus of camel in the family Camelidae, Originating in North America during the Mid Miocene, but, after crossing over the Beringian land bridge during the late Miocene, approximately 7.5-6.5 Ma., it ranged from Spain to Chad and Shanxi Province, China. It is ancestral to living camels of the genus Camelus.[citation needed] A population survived in northern North America; called the high Arctic camel, this survived until the Mid Pleistocene approximately 1 Ma.[3]

TaxonomyEdit

Paracamelus was named by Schlosser (1903). Its type is Paracamelus gigas. It was assigned to Camelidae by Carroll (1988).[4]

Fossil distributionEdit

The earliest fossil of Paracamelus is from the mid Miocene Esmeralda Formation in Nye County Nevada and is between 10-12.5 million years in age.[5] After a sea level transgression event, the genus spread to Eurasia arriving in Spain and Italy just prior to the Messinian Salinity Crisis at approximately 6 Ma,[6] before Spreading to Africa around the Miocene-Pliocene boundary.[7]
