Suchomimus was a large, meat-eating dinosaur with a crocodile-like mouth that lived 110 to 120 million years ago, during the middle Cretaceous period.
Characteristics and environment
Unlike most giant theropods, Suchomimus had a very long, low snout and narrow jaws studded with some 100 teeth, not very sharp and curving slightly backward. The tip of the snout was enlarged and carried a "rosette" of longer teeth. The animal is reminiscent of crocodilians that eat mainly fish, such as the living gharial, a type of large crocodile with a very long, slim snout, from the region of India.
Suchomimus also had a tall extension of its vertebrae which may have held up some kind of low flap, ridge or sail of skin, as seen in much more exaggerated form in Spinosaurus. The overall impression is of a massive and powerful creature that ate fish and meat more than 100 million years ago, when the Sahara was a lush, swampy habitat.
Classification
Suchomimus has been placed among the spinosaurs, a group of predators. Apart from the back ridge, Suchomimus was very similar to Baryonyx which also had strong forelimbs and a huge sickle-curved claw on its "thumb". And, as with Baryonyx, the claw was the first fossil part to be noticed by palaeontologists. Suchomimus was considerably larger than Baryonyx, but the latter might almost have been a juvenile of the former. Detailed study shows that the specimen of Suchomimus was itself not fully grown when it died.
Discovery
After discovering a new specimens of Carcharodontosaurus and the SuperCroc, Chicago-based palaeontologist Paul Sereno and his team added a discovery in 1997. In the Sahara, near the Tenere Desert in Niger, they found fossils that represented about two-thirds of the skeleton of a huge meat-eater. This was named Suchomimus ("crocodile mimic") after the shape of its head.
