The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary (K–T) extinction, was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.
Dinosaurs that failed to adapt went extinct. But then 66 million years ago, over a relatively short time, dinosaurs disappeared completely (except for birds). Many other animals also died out, including pterosaurs, large marine reptiles, and ammonites.
Extinction. A misconception commonly portrayed in popular books and media is that all the dinosaurs died out at the same time—and apparently quite suddenly—at the end of the Cretaceous Period, 66 million years ago. This is not entirely correct, and not only because birds are a living branch of dinosaurian lineage.
Hace 65 millones de años se extinguió el último dinosaurio. Los gigantescos mosasaurios y plesiosaurios en los mares y los pterosaurios en los cielos. Muchas familias de braquiópodos y esponjas de mar desaparecieron. Los restantes ammonites de concha dura se esfumaron.
