spinosaurus is a genus of theropoddinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanianstages of the Cretaceousperiod, about 112 to 97 million years ago. This genus was first known from Egyptian remains discovered in 1912 and described by GermanpaleontologistErnst Stromer 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 S. aegyptiacus from Egypt, although a potential second species S. maroccanus has been recovered from Morocco. It also has a top speed of 23-24 miles
