Bringing up baby: A crocodile's changing niche

Relatives of the giant crocodile might have been kings of the waterways during the Cretaceous period, eating anything—including dinosaurs—that got a little too close to the water's edge, but the largest of these apex predators still started off small. Figuring out how these little crocs grew up in a world surrounded by giants is no small task. Now crocs fossils from Texas are shedding light on how these animals changed their diets as they grew, helping them find a place of their own in environments alongside their bigger, badder relatives.
