First appearing approximately 230 million years ago, the hearty crocodilians — alligators, crocodiles, caimans and gharials — have survived nearly every earthly scenario. They have outlived dinosaurs, ice ages, mass extinctions and more, yet they have changed very little over time. Find out all you ever wanted to know about crocodilians, plus a menagerie of wild reptiles and amphibians from North Carolina and around the world, at the North Carolina Museum of Natural Sciences’ Reptile & Amphibian Day, Saturday, March 9, 10 a.m.–5 p.m.
