Crocodile Ancestors Tracked Warm Climates for 250 Million Years

New research in Science Advances finds that crocodile-line animals kept a stable warm-climate preference for 245 million years, shifting toward the poles when the planet warmed and back toward the equator when it cooled. This loyalty may have placed survivors in equatorial refuges after the asteroid impact 66 million years ago, helping them outlast non-avian dinosaurs.
