At 40kg, the cazarrino (Notovenator pictus) is a typical South American notovenatorine tyrannosaur.  These fast little predators sport the long tails, atrophied arms, and two-toed feet of all notocentatorines.  Cazzarinos hunt for mammals and small dinosaurs in their grassland home, mimicking their cousins, the North American errosaurines, which live on the other side of the equator.
