Carcharodontosaurus – Discover One Of The Worlds Largest Predatory Dinosaurs

Carcharodontosaurus Roaring

Carcharodontosaurus, one of the most formidable predators of the mid-Cretaceous period, roamed North Africa approximately 100 to 93 million years ago.

This massive theropod, whose name means "shark-toothed lizard," was named for its large, serrated teeth, which were similar to those of today's great white shark.

Measuring up to 13 meters (43 feet) in length and weighing as much as 15,000 kilograms (33,000 pounds), Carcharodontosaurus was a dominant force in its ecosystem.

Discovered in the Sahara Desert in the 1920s, this dinosaur has since captured the fascination of paleontologists and dinosaur enthusiasts alike, providing critical insights into the diverse and dynamic world of prehistoric predators.
