Dinosaur of the Week: Spinosaurus!

Spinosaurus = win.

Spinosaurus is a genus of theropod dinosaur whose fossils have been found in North Africa. It walked the Earth during the Cretaceous period. You may remember from your childhood that this is the terrifying beast characterized by a large spine that runs across the length of its back like a sail (or something). It makes one curious about the function of such a spine; perhaps it was used for display, or perhaps to regulate body temperature. Perhaps to accessorize. We’ll never know, because it’s hard to say if the spine was covered by muscle, cartilage, skin, etc, and to what degree the spines were connected (or not).

The most awesome thing about this almost crocodilian carnivore is its sheer size: Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than everyone’s favourite Tyrannosaurus Rex or Gigantasaurus! So get out the way foolish little pack hunters, cause Spiny’s out hunting. Like a boss.
