Crocs were relieved when that big rock hit at Chicxulub.

Croc-a-toe-a.................
Crocks were able to survive because they tend to hibernate by sleeping in holes dug out under the banks of streams and rivers. I don’t know if the 50’ ones did that back in the dinosaur age, but I bet a lot of smaller young ones did have that habit which meant many more Crocks were there after the big blast that dinosaurs. Also crocks could probably survive much longer without food than dinosaurs. Whatever species survived the initial world wide disaster then had to survive the equivalent of a “nuclear winter” which may have lasted for years.
