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]
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).
