***Dutuitosaurus*** is a [genus](/source/Genus) of [metoposaurids](/source/Metoposauridae), a group of [temnospondyls](/source/Temnospondyl) that lived during the [Late Triassic](/source/Late_Triassic) period. *Dutuitosaurus* was discovered in the early 1960s in Morocco and is known from the lower t5 units of the [Timezgadiouine Formation](/source/Timezgadiouine_Formation) exposures in the [Argana Basin](https://en.wikipedia.org/w/index.php?title=Argana_Basin&action=edit&redlink=1) of the [High](/source/High_Atlas) [Atlas Mountains](/source/Atlas_Mountains) and was first described in 1976 by French paleontologist Jean-Michel Dutuit.[1] Material of *Dutuitosaurus* is currently held in the [Muséum national d'histoire naturelle](/source/National_Museum_of_Natural_History_(France)) (MNHN) in Paris, France.[2][3] It was originally placed within *[Metoposaurus](/source/Metoposaurus)* as *M. ouazzoui* but was subsequently placed in its own genus, *Dutuitosaurus*, by Hunt (1993), who identified a number of differences between *Metoposaurus* (classically a European genus) and the Moroccan metoposaurids.[4] Features that differentiate *Dutuitosaurus* from other metoposaurids include relative elongate intercentra and a maxilla that enters the orbit.[4]

Although many metoposaurids are known from so-called mass death assemblages that preserve large skeletal accumulations, the deposits in which *Dutuitosaurus* was found are relatively unique in preserving several completely articulated skeletons (over 70 individuals are present). This is interpreted to represent a relatively in situ preservation, possibly by the drying up of a pond as was classically proposed by Romer (1939),[5] rather than transport of large amounts of remains into another area that would have become progressively disarticulated, as is probably the case with other metoposaurid mass death assemblages.[6] Because most other metoposaurids are only known from a collection of dissociated skeletal elements, *Dutuitosaurus* is frequently taken as the guide for inferring skeletal proportions and precise positions of different elements in metoposaurids.[7]
