Tengrisaurus (meaning "Tengri lizard") is a genus of lithostrotian sauropod, from the Early Cretaceous (Barremian-Aptian), of the Murtoi Formation, Russia. It was described in 2017 by Averianov & Skutschas. The type species is T. starkovi.[1]

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

Amerianov and Efimov (2019) recovered Tengrisaurus as a lithostrotian 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.[2]

Tengrisaurus

	Isisaurus

	Saltasauridae

Pitekunsaurus

Volgatitan

Epachthosaurus

	Muyelensaurus

	Rinconsaurus

	Lognkosauria
