Suchomimus tenerensis (meaning "crocodile mimic from Tenere," after the part of the Sahara desert where it was found) was a fish-eating (and meat-eating) spinosaurid theropod dinosaur. It was about 36 feet (11 m) long, about 12 feet tall, and walked on two powerful hindlegs. This carnivore had short clawed arms with three fingers. One finger on each hand had a 1-foot long, sickle-like claw on the end of a 16-inch (40 cm) long thumb. "The hand is amazing," Sereno said. "It was probably ideal for fishing, for grabbing ... into those large fish."
In its crocodile-like pointed jaw, it had about 100 pointed teeth. These razor-sharp teeth faced slightly backwards. The very end of the snout was tipped with an extra, chin-like projection, called a rosette, that held the longest teeth, ideal for grabbing prey.
