Suchomimus is a genus of dinosaur belonging to the group Spinosauridae. It lived during the Early Cretaceous period, approximately 121 to 112 million years ago. The first fossils of Suchomimus were discovered in the Ténéré Desert of Niger, Africa, in 1997.

Suchomimus was a large theropod dinosaur, one of the largest known spinosaurid dinosaurs. measuring around 36 to 40 feet (11 to 12 meters) in length and weighing approximately 5 to 7 tons. Its body was well-adapted to a semi-aquatic lifestyle, with long and slender jaws containing numerous conical teeth ideal for catching slippery prey in the water. Suchomimus had a long and slender snout (brought inspiration to the name also), which was a noticable trait amongst all spinosaurids. It had pointy teeth with very fine serrations. Suchomimus had strong forelimbs and a sickle-like claw on each thumb. The nature of its teeth combined with its long snout hinted that it may have not hunted large prey and that it fed mostly on fish.

It´s nasal passages stretched all the way to the back of the mouth cavity, as they do in living mammals and crocodiles, and did not open within the mouth as they do in many living reptiles and most dinosaurs. It is uknown why these features developed in the first place. This feature did however have its advantages, it could be submerged in the water with only the tip of the snout outside the water being able to breath and stalk prey.

It was first found in Niger, Africa by an American party from Chicago.
