Spinosaurus Tooth, from Morocco (No.140)

Spinosaurus (meaning "spine lizard") is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.

  

This genus was first known from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer (12 June 1870 - 18 December 1952) in 1915. The original remains were destroyed in World War II, but additional material has come to light in recent years. It is unclear whether one or two species are represented in the fossils reported in the scientific literature. The best known species is Spinosaurus aegyptiacus from Egypt, although a potential second species Spinosaurus maroccanus has been recovered from Morocco.
