Diet: It is conflicting on whether it only ate fish or other dinosaurs, but recent evidence shows it may have eaten only aquatic animals. 

Anatomy: Spinosaurus has been very popular due to its large sail. The sail differs from other sails dinosaurs have. Some point that the sail is more like a hump. The use is not well known. Some speculate it was for temperature regulation. 

Behavior: Not much is known about its behavior. It is recently shown that it was aquatic, so it would spend most of its life swimming and hunting.

Relationship with other animals: Crocodilians in the area would share a strong rivalry with the dinosaur of the deep savers, as the food would have been similar.
