Piatnitzky's Lizard

Named and described by Jose Bonaparte in 1979 for the Russian born Argentinian paleontologist Alejandro Matveievich Piatnitzky, Piatnitzkysaurus floresi is a 4.3 m (14 ft) 450 kg (990 lb) bipedal Jurassic carnivore of Patagonia. The dinosaur is known from two partial skeletons, one of which is composed of a partial cranium and postcranial elements. Significant portions of postcrania constitute the second individual initially described by Bonaparte. The dinosaur is similar to many other contemporaneous predators, though separated by oceans. and general environment.
