Discovered by Ernst Stromer in 1915, the original fossils were destroyed during a bombing in World War II. It is not sure that recent scrappy fossils found in Morocco are the same species as the originals from Egypt.
In the 1990s and 2000s, more fossils were discovered that revealed parts of the snout, head and teeth, revealing that its head featured a short crest and a long, narrow snout. These remains helped solidify the belief that it fed primarily on fish.
More complete remains discovered in 2014 were described by Nazir Ibrahim and Paul Sereno. Their description suggest that Spinosaurus may have been more suited to a four-legged manner of movement, with smaller hind limbs than previously thought. If accurate, this drastically new idea of Spinosaurus as a swimming, semi-aquatic creature makes it even more unique among the theropod dinosaurs.
The Spinosaurus is found in north Africa and lived in Mangrove swamps.
