One of the few Middle Jurassic Dinosaurs known, this tetanuran is of uncertain lineage, some think it's an ancestor to Abelisaurids, but most think it's just a basal tetanuran more closely related to the carnosaurs.
never heaard that it could be a relative of abelisaurids, where do you get that info,
didn't these guys live somewhere in ancient patagonia?
Yeah. But no one quite knows where to place these. Originally they were thought to be tetanurans and the precursor of the Gondwanian large carnosaurs, like Carcharodontosaurus and so on, but paleontologists are looking into the possibility that is actually a Ceratosauroid from a family which we know little or nothing about, and that these are actually the precursors of Abelisaurids in Gondwana, while Ceratosaurs disappear from above the Equator after the Jurassic.
thing for dinos uh,...nice detail on this
De todos mudos un "lindo" carnivoro.
Best Piatnitzkysaurus I've seen!
