Thalassotitan had teeth like a killer whale, thick and cone-shaped, perfect for grabbing big prey.12
It was an apex predator, meaning it was at the top of the food chain, like orcas and white sharks today.12
Some fossils found near Thalassotitan show acid damage, which scientists think came from being eaten and partly digested by this mosasaur.12
Thalassotitan lived about 67 to 66 million years ago, right before the dinosaurs went extinct.1
Its skull was broad and its jaws were massive, built for biting hard and crushing prey.2
Thalassotitan is part of a group called Prognathodontini, known for their strong jaws and thick teeth.1
