Allosaurus
A 30-foot-long, two-legged cross between a crocodile and a mountatin lion. Add a huge skull and the predatory behavior of a shark. That's Allosaurus
This was how a 1993 issue of National Geographic appropriately described this remarkable animal. Allosaurus was the most common & successful predator of the late Jurassic. These theropods are often referred to as "the wolves of the Jurassic" because they so were so widespread (A. fragilis is the only theropod species positively identified on more than one continent) and they are believed to have been pack hunters. Thousands of fossilized bones (in a few cases,nearly complete skeletons) found throughout North America has made Allosaurus one the most well understood of all predatory dinosaurs.

Albertosaurus
Although the small flesh-eating dinosaurs were diverse and dangerous, Cretaceous Alberta was ruled by members of the family Tyrannosauridae. All tyrannosaurs had hind legs that were long and powerful, with each hind foot having three toes ending in enormous claws. The two-fingered front limbs were small, not much larger than a mature human arm. The function of the front limbs is not known; they are too short to have passed food to the mouth.
