Today's living night lizards—like Xantusia vigilis (pictured)—are descendants of a common ancestor that lived roughly 90 million years ago, well before the Chicxulub asteroid struck Earth 66 million years ago.

These Lizards Mysteriously Survived the Asteroid Strike That Killed the Dinosaurs—and Their Descendants Are Still Alive Today

Small and elusive night lizards probably persisted because they have slow metabolisms and like to hide out in rock crevices, a new study suggests

The Famous, Feathered Dinosaur Archaeopteryx Could Fly, Suggests New Study of a ‘Beautifully Preserved’ Fossil

The Chicago Archaeopteryx features more soft tissue and delicate skeletal details than any known fossil of its kind, and paleontologists discovered it has a set of feathers key to flight in modern birds

Crocodile-like sebecids were known to roam South America after dinosaurs went extinct. Recently found fossils suggest they inhabited the Caribbean as well—and thrived there long after they disappeared on the continent.

Fossils Reveal Enormous, Crocodile-Like Reptiles Survived for Millions of Years Longer Than Previously Thought

New discoveries in the Dominican Republic suggest sebecids roamed the Caribbean as recently as 4.5 million years ago, long after they vanished from South America
