Discovery and naming

edit

The holotype, AMNH 5688, consists of several fossilized vertebra, portions of a few limbs, and ribs.[1][2]

Uronautes cetiformis was first described by the American paleontologist Edward Drinker Cope in 1876.[1] Welles (1956) described the genus as a "nomen dubium", doubting that the remains were evidence of a true genus.[3]

Etymology

edit

The word Uronautes comes from a fusion of the two Greek words Ουρα, meaning "tailed," and Ναυτεσ, meaning "sailor", or "mariner".[4] The species name of U. cetiformis comes from the Greek word for whale (or any large sea monster), κῆτος and the Latin word forma, which means "shaped", of "formed" meaning "shape".[5]

Description

edit

Like many other rhomaleosaurids, Uronautes was a short-necked plesiosaur. The cervical vertebrae are short, with partially attached processes and double-headed ribs.[6]
