CRETACEOUS SPINE LIZARD
Spinosaurus was a huge carnivorous theropod dinosaur who lived in the swamps of North Africa during the upper Albian to upper Turonian stages of the Cretaceous, some 112 to 93.5 million years ago.
Larger even than some Tyrannosaurus and Giganotosaurus, this fellow weighed up to 21,000 kg and with all that mass was still an accomplished swimmer.
