Eocarcharia (meaning "dawn shark") is a genus of carcharodontosaurid theropod dinosaur that lived in the Sahara 112 million years ago, in what today is the country of Niger. It was discovered in 2000 on an expedition led by University of Chicago paleontologist Paul Sereno. The type and only species is Eocarcharia dinops. Its teeth were shaped like blades and were used for disabling live prey and ripping apart body parts. Eocarcharia’s brow is swollen into a massive band of bone, giving it a menacing glare. It was one of the many gigantic theropod dinosaurs found in the Sahara and among the largest carnivores to ever live on Earth.Eocarcharia was 8-9 meters in lenght it ate sauropods such as Nigersaurus and became extinct 110 millions years ago probally because of food competition with Spinosaurus,Carcharodontosaurus and Sarcosuchus and their prey changed and became more difficult to eat.
