The Ceratosaurus, a dinosaur known for having a horn on the top of its nose, is also known to be a decendent of the Tyrannosaurus Rex.

The statement is false. Ceratosaurus is not a descendant of the Tyrannosaurus rex. They are actually part of two different branches within the dinosaur evolutionary tree. Ceratosaurus belongs to a group called the Ceratosauria, which includes various medium-sized theropods, while Tyrannosaurus rex belongs to the group called the Tyrannosauridae, which includes large carnivorous dinosaurs. Although both lived around the same time during the late Jurassic period, there is no direct ancestral relationship between them.
