In Depth

       Currently considered to be a megalosauroid theropod,‭ ‬Piatnitzkysaurus was a smaller medium sized theropod of the Jurassic.‭ ‬As a predator Piatnitzkysaurus probably hunted other small dinosaurs and possibly even those slightly larger than itself.‭ ‬It is also almost a certainty that Piatnitzkysaurus would scavenge the carcasses of dead dinosaurs when able,‭ ‬since scavenging is a frequent and often observed feeding strategy in most predatory animals that are capable of killing their own prey.

       Hailing from the Canadon Asfalto Formation,‭ ‬Piatnitzkysaurus likely lived alongside other dinosaurs such as Eoabelisaurus,‭ ‬Patagosaurus,‭ ‬Volkheimeria and Tehuelchesaurus.‭ ‬However it is actually a dinosaur from France called Piveteausaurus that is considered to be one of the dinosaurs most similar to Piatnitzkysaurus in form.
