The T. rex is often painted as the king of dinosaurs and the cretaceous. And thanks to this title, it is sometimes regarded as being the largest predator of its era. However, despite being the largest carnivorous dinosaur, it was not actually the biggest predator to live during the cretaceous or even during its own existence, as that honor went to something much more sinister, the Mosasaurus.
