Info

Genus - Typespecies

Borealosaurus wimani is based on a distinctive mid-distal caudal vertebra, provisionally refered are an isolated tooth crown, a mid caudal vertebrae and a right humners from the same locality and horizon. Borealosaurus is distinguished from other sauropods in its possesion of opisthocoelous mid-distal caudal vertberae. The occurence of opisthocoelous caudals in Borealosaurus and the Mongolian sauropod Opisthocoelicaudia raises the possibility that these taxa pertain to an as yet unrecognized titanosaurian subclade endemic to the Cretaceous of Asia.
