A newly discovered dinosaur species bridges the gap between the earliest known group of predators and more advanced beasts such as Tyrannosaurus rex, according to a new study.
Found at New Mexico's Ghost Ranch fossil site, the primitive dinosaur lived about 205 million years ago.
The dinosaur, which stood as tall as a large dog, boasts a very unusual skull. It has a deep, short snout and these monstrous front teeth. That's a kind of skull structure for a predatory dinosaur that's really unexpected for this early point in time.
These features helped earn the new dinosaur the name Daemonosaurus chauliodus, or "buck-toothed evil spirit" in Greek.
