Tengrisaurus (meaning "
sauropod, from the Early Cretaceous (Barremian-Aptian) Murtoi Formation, Russia. It was described in 2017 by Averianov & Skutschas. The type species is T. starkovi.[1] New remains were described in 2021 by Averianov, Sizov & Skutschas.[2]
Description
Tengrisaurus starkovi is based on three caudal vertebrae. The genus is characterized by strongly procoelous anterior and middle caudal vertebrae, with strongly developed pre-epipophyses, highly pneumatic neural spine, and solid bone structure of the centrum.[1]
Classification
Averianov and Efimov (2018) recovered Tengrisaurus as a
titanosaur. They found Lithostrotia to be divided into two main lineages, one containing Saltasauridae, the other containing Lognkosauria, with Tengrisaurus belonging to the former. The following cladogram follows their analysis.[3]
