First Swimming Dinosaur "Half-Duck, Half-Crocodile"

Only Dinosaur that lived in water?

     The fearsome Spinosaurus is one of the icons of the dinosaur pantheon. It was larger than T. rex (and larger than all other carnivorous dinosaurs, in fact), and on its back it sported a sail taller than an adult man. Now, researchers have discovered something even more astonishing about this ancient beast. Spinosaurus was the only known dinosaur adapted to living almost entirely in the water. 

     Around 97 years ago, in a river system now known as Africa, the Spinosaurus sliced through the water, snaring fish in its cone-shaped, interlocking teeth. New fossils reveal that the 50-foot-long (15 meters) dinosaur had a host of adaptations for an aquatic lifestyle, including flat, possibly webbed feet and nostrils high up on its head.

     With a guide to lead them to the Spinosaurus site, the researchers discovered even more bones, all from the same individual dinosaur. They soon realized that these bones were very strange indeed. They were very dense, without the hollow medullary cavity found at the center of the long bones of the arms and legs in most animals. Dense bones like these are found in marine animals and function as a sort of buoyancy control.

     I wasn't really big into science too much as a child, but when I see something that I think is interesting I'll read it. When I was younger I liked dinosaurs. I read books, magazine articles, and went to museums and I also watched then Land Before Time movies. I think my favorite dinosaur was the T-Rex because it was one of the most dominate dinosaurs back then. When I first saw this article it got me excited because I'm more it science now and it was cool to read about dinosaurs again.
