Velociraptor is one of the most bird-like dinosaurs ever discovered. It was small and fast, and the sickle-shaped claw on the second toe of each foot made it a formidable predator. A special bone in its wrist allowed it to swivel its wrist sideways in a flapping motion and to fold its arm against its body like a bird. This motion allowed it to snap its arms forward to grab fleeing prey and is an important part of the flight stroke in modern birds.

Spinosaurus....the SPINY !!!
Spinosaurus is a carnivorous dinosaur that lived in what is now Northern Africa during the Cretaceous period—about 110 million years ago. Most scientist agree that this dinosaur probably hunted both on land and in water and probably lived on a diet of both fish and small mammals. It is believed these dinosaurs floated in much the same way that modern crocodiles do; lying in wait and then using the element of surprise to hunt prey. They were first discovered in 1912 in Western Egypt by Richard Markgraf, although this original specimen was destroyed during the bombing of Munich, Germany during World War II. Since then, scientists have had to make due with studying the plaster casts of this animal.
More About Parasaurolophus....
When Parasaurolophus was first discovered, speculation about its bizarre-looking crest ran rampant. Some paleontologists thought this dinosaur spent most of its time underwater, using its hollow head ornament like a snorkel to breathe air, while others proposed that the crest functioned as a weapon during intra-species combat or even had specialized nerve endings that could "sniff out" nearby vegetation.
