Abdarainurus (meaning "Abdrant Nuru tail" after the holotype locality) is a genus of titanosaur dinosaur from the Alagteeg Formation in Mongolia. The type and only species is A. barsboldi. Currently seen as an indeterminate titanosaur, it may represent a previously unknown lineage of Asian macronarians.[1] Abdarainurus is not known from many remains; it is only known from eight front tail vertebrae and a middle tail vertebra and several chevrons.
Discovery and naming
The holotype, PIN 5669/1, was discovered in 1970 in Abdrant Nuru, hence the genus name, during a Joint Soviet–Mongolian Paleontological expedition and was excavated by V. P. Tverdokhlebov of Saratov State University. The fossils were left unprepared until at least 2000, when paleontologist Andrei Podlesnow revealed that they probably belonged to a new genus of sauropod.[2] The species Abdarainurus barsboldi was named in February 2020.[1]
Paleoecology
Abdarainurus was discovered in the Abdarant Nuru locality of the Alagteeg Formation (which may be the same unit as the overlying Djadochta Formation)[3] of Mongolia[1] and coexisted with the ankylosaur Pinacosaurus sp., and indeterminate turtles and dinosaurs.
