The Sarcosuchus is an extinct African reptile that is a relative of the crocodile. They existed in the Cretaceous period of the prehistoric era, but aren't dinosaurs. Sarcosuchus is sometimes known as SuperCroc, and are 11.2-12.2 meters long when fully grown.
The long snout of the Sarcosuchus was used to grab and devour Cretaceous fish and turtles. It cruhed and tore apart its prey, which it powerfully dragged into the water.
