Piatnitskysaurus NT


Piatnitzkysaurus (named to honor Alejandro Mateievich Piatnitzky (1879-1959), Russian-born Argentine geologist) is a genus of theropod dinosaur. It is known from the Canadon Asfalto Formation, Middle Jurassic (Callovian stage) of what is now Argentina. Once thought to be a basal carnosaur,[2] it may instead be a megalosauroid.[1] Partial skeletons are known (two fractured skulls and parts of the postcranial skeleton) and show Piatnitzkysaurus was a lightly built medium-sized bipedal carnivore with robust arms around 4.3 metres (14 ft) long and around 450 kilograms (990 lb) in mass, though such estimates apply to the holotype, which is a subadult.[3] Its ischium is 423 millimetres (16.7 in) long.[4] Its braincase resembles that of another megalosauroid, the megalosaurid Piveteausaurus from France.[5]


The type species, Piatnitzkysaurus floresi, was described by Jose Bonaparte in 1979.
