Borealosaurus

Borealosaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of northern China. The type and only species is Borealosaurus wimani, based on fragmentary remains from the Sunjiawan Formation, Liaoning. It has been estimated that this creature measured 12 metres in length, with a weight of 10 tonnes. The morphology of a mid-distal caudal vertebra suggests a relationship with the Mongolian titanosaur Opisthocoelicaudia.

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