In fact, they are living beings that have continuously evolved, changed, and adapted for over 250 million years! From small terrestrial crocodiles in the Triassic period to apex marine predators in the Jurassic and Cretaceous, they survived not one, but two mass extinction events—enduring into the modern age with only three major families remaining today. In this video, we’ll take you back to the origins of the archosaurs—a group more closely related to birds than to lizards. You’ll learn about convergent evolution, and how crocodiles adapted through the ages—from early land-dwelling species, to oceanic crocodiles that swam like sharks, dinosaur-eating giants, herbivorous crocodiles, even plankton-filtering varieties. We’ll explore how some lineages survived the catastrophic asteroid impact that wiped out the dinosaurs—thanks to their extraordinary resilience. We’ll also explore how crocodiles re-adapted to land after the age of dinosaurs, competed with mammals, and eventually evolved into the three semi-aquatic families we know today. This story will transform how you see crocodiles— They never stopped evolving!
