From bone-crushing jaws to tail spikes the size of swords, prehistoric animals developed some of the deadliest weapons in natural history. This video explores the insane weaponry of extinct animals, including the hydraulic press bite of Tyrannosaurus, the sickle claws of dromaeosaurs and terror birds, the meter-long thagomizers of stegosaurs, the powerful paws of Arctodus simus, the pincers of eurypterids, supersonic tail whips of sauropods, and much more. Included is a ranking of how painful it would be for each of these prey-dispatching or defensive methods to be used on a human being. So what was the worst way to die in prehistory? Let’s find out!

![Whats The Size Limit Of Crocodiles? Paleontology Analysis
Crocodiles, some of the most vicious predators in our planets history, are known for their size and power. How big did crocodiles get? In this video, Vividen explores how prehistoric crocodyliformes like Sarcosuchus, Deinosuchus, and Purussaurus approached tyrannosaur-level size and what that could mean for the theoretically biggest crocodiles of all time.
