Narindasaurus (meaning "lizard of Narinda Bay") is a genus of turiasaurian sauropod dinosaur from the Middle Jurassic Isalo III Formation of Madagascar.[1][2] The type species, N. thevenini was formally described by Royo-Torres et al. in 2020.[3] The holotype, which consists of one specimen, is currently stored at the Muséum national d’Histoire naturelle and has been since 1906 or 1907.[2]
Discovery and naming
The holotype was discovered in the Isalo III Formation before 1894 by Joseph Thomas Last,[4] and were briefly noted on by Paul Lemoine in 1906.[1] Armand Thevenin (1861-1942) was the first to diagnose Narindasaurus. In 1907, he placed it within the now obsolete species "Bothriospondylus madagascariensis",[2] which is now known as Lapparentosaurus.[5] It was briefly mentioned in 1972[6] and it was reevaluated in 2008 and 2010 as both a distinct taxon and a non-neosauropod eusauropod.[7][8] It was classified as a turiasaur in 2015.[9] The species Narindasaurus thevenini was formally named in 2020.[3]
The holotype consists of a partial skeleton composed by a right maxillary or premaxillary tooth (MNHN MAJ 423), an anterior caudal vertebra (MNHN MAJ 424), a posterior caudal vertebra (MNHN MAJ 426), a middle-anterior chevron (MNHN MAJ 425), a right ulna (MNHN MAJ 427), a right tibia (MNHN MAJ 428), a right fibula with a distal chevron attached (MNHN MAJ 429) and a left pubis (MNHN MAJ 430).[2][3]
