Caseosaurus

Nomen dubium

Case's lizard

  • Case · English · surname of American paleontologist Ermine Cowles Case
  • saurus · Greek · lizard

Caseosaurus is named in honour of the American vertebrate paleontologist Ermine Cowles Case (1871–1953), who made significant contributions to the study of Permian and Triassic reptiles. The second element, '-saurus', comes from the Greek word 'sauros', meaning 'lizard', a standard suffix in dinosaur and reptile genus names. The name therefore translates literally as 'Case's lizard'. It was named as a tribute to Case's extensive work on early Triassic faunas of the American Southwest.

Caseosaurus crosbyensis is known only from a partial ilium. It was originally described as a herrerasaurid dinosaur (a very early theropod-line dinosaur), but subsequent analyses have questioned its referral, and some researchers consider it a nomen dubium due to the fragmentary and non-diagnostic nature of the material. Its classification as a dinosaur at all remains uncertain.
