Borealosaurus

Borealosaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of northern China. The type species is Borealosaurus wimani, which was named in 2004.

==Description== The type and only species is Borealosaurus wimani, based on fragmentary remains from the Sunjiawan Formation of Liaoning. The morphology of a mid-distal caudal vertebra was considered suggestive of a relationship with the Mongolian titanosaur Opisthocoelicaudia. However, in their overview of Cretaceous sauropod remains from Central Asia, Averianov and Sues considered Borealosaurus a non-lithostrotian titanosaur due to the lack of procoely in the middle caudal vertebrae.
