Chuandongocoelurus (.
Discovery and naming
The
Sichuan Province and the theropod genus Coelurus, itself named after the Greek κοῖλος, koilos, meaning "hollow" and οὐρά, oura, meaning "tail". The specific name means "the primitive one" in Latin, a reference to the great age of the find.[1]
He assigned two partial skeletons to Chuandongocoelurus. The
Lower Shaximiao Formation, meaning Chuandongocoelurus dates to the Bathonian or Callovian stage of the Middle Jurassic
.
The holotype thighbone has a length of 201 millimetres.[1]
Classification
He placed Chuandongocoelurus in the
sister taxon of Monolophosaurus, together forming a clade belonging either to Megalosauroidea[4][5] or outside of Megalosauroidea in the Tetanurae.[6] In 2012, Matthew Carrano et al. found Chuandongocoelurus outside of the Megalosauroidea.[2]
