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. It was described by Hailu, Qiang, Lamanna, Jinglu and Yinxiang, in 2004. It was named from
Greek '''' (the North wind) and (lizard), with its specific name being given in honor of
Swedish paleontologist Carl Wiman, who named the first Chinese dinosaur. ==References==
