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.[1]
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.[2]
It was described by Hailu, Qiang, Lamanna, Jinglu and Yinxiang, in 2004. It was named from Greek Greek, Ancient (to 1453);: Βορεας (the North wind) and Greek, Ancient (to 1453);: σαυρος (lizard), with its specific name being given in honor of Swedish paleontologist Carl Wiman, who named the first Chinese dinosaur.[3]
