You'd think it would be an easy matter to identify any given dinosaur as a tyrannosaur, but the fact is that these fierce hunters (typified by Tyrannosaurus Rex) were often barely distinguishable from other large theropods like allosaurs and abelisaurs. A case in point is Labocania: most paleontologists tentatively classify this dinosaur as a true tyrannosaur, while others maintain that it was more closely related to Allosaurus (a dinosaur that went extinct tens of millions of years before Labocania arrived on the scene). Whatever the case, the 20-foot-long Labocania was certainly one of the most feared predators of late Cretaceous Baja California, where its remains were found.
