How night lizards survived the asteroid that ended the dinosaurs‎

Yale University ecologists reveal a lizard lineage that rode out the dinosaur-killing asteroid event with unexpected evolutionary survival traits. Night lizards (family Xantusiidae) survived the Cretaceous–Paleogene (K-Pg) mass extinction event 66 million years ago (formerly known as the K-T extinction) despite having small broods and occupying limited ranges, a departure from the theory of how other species are thought to have persisted in the aftermath of the event.
