The holotype, IVPP AS 40002-3, was found near Paikushan, Luanshantze, in sandstone of the Shishugou Formation dating from the Oxfordian. It consists of elements of the postcrania. A considerable part of the skeleton is known but not the skull or the lower jaws. The body length has been estimated at twelve metres.
In 1991 Ralph Molnar renamed Euhelopus zdanskyi to Tienshanosaurus zdanskyi,[2][failed verification] despite the species having priority over T. chitaiensis, made possible by the fact that Euhelopus is a renaming of the earlier Helopus. Meanwhile, Valérie Martin-Rolland renamed T. chitaiensis into Euhelopus chitaiensis.[3]
Due to the fragmentary nature of the material and a limited description, it has not been easy to establish the affinities of Tienshanosaurus. Originally classified in the
