But in fact, they were killed off at the end of the Cretaceous period – the fifth of the ‘Big Five’. End Cretaceous (65 mya) – the event that killed off the dinosaurs.

The End of the Dinosaurs: The K-T extinction. Almost all the large vertebrates on Earth, on land, at sea, and in the air (all dinosaurs, plesiosaurs, mosasaurs, and pterosaurs) suddenly became extinct about 65 Ma, at the end of the Cretaceous Period. At the same time, most plankton and many tropical invertebrates, especially reef-dwellers ...The pattern of the end-Cretaceous extinction and its causes have been debated for over two hundred years. A giant asteroid impact in the Yucatan peninsula has been linked to their demise, although ...We all think we know what happened to the dinosaurs: 66 million years ago, at the end of the Late Cretaceous, an asteroid hit the planet and wiped them out. But that’s far from the whole story.
The Cretaceous Period is a classic example of a “greenhouse state” in Earth history (Skelton, 2003) that was marked by rapid climate perturbations, multiple oceanic anoxic events (OAEs), deposition of oceanic red beds (CORBs), intense volcanic activities and a long period of normal geomagnetic polarity (Cretaceous Normal Superchron: …If you have trouble remembering names (like I do sometimes), a great way to help yourself remember is to start and end your first few conversations (especially your first one) with a person's name.

Scientists had agreed that a massive meteorite made impact approximately 66.04 million years ago at the Cretaceous-Paleogene (known as K-Pg) boundary, as identified through a geological record in crust and rock. The site is located under Mexico’s Yucatán Peninsula near the town of Chicxulub and has been identified as the crater that …Introduction.

At the end of the Cretaceous, 66 million years ago a large asteroid crashed into the earth north of the Yucatan peninsula and eliminated about three-quarters of the life on earth. The asteroid that hit Earth in what is now the Gulf of Mexico was 6-12 miles in diameter, producing a crater nearly 120 miles wide and 12 miles deep.
Elasmobranchs declined by >62% at the Cretaceous-Paleogene boundary and did not fully recover in the Paleocene. The end-Cretaceous event triggered a heterogeneous pattern of extinction, with rays and durophagous species reaching the highest levels of extinction (>72%) and sharks and nondurophagous species being less affected.During the End-Cretaceous (K-T) extinction (65 million years ago) eighty-five percent of all species disappeared, making it the second largest mass extinction event in geological history. This mass mass extinction, extinction event has generated considerable public interest, primarily because of its role in the demise of the dinosaurs.The Cretaceous witnessed the climax of the dinosaurs' evolutionary innovation, occurring immediately before the mass extinction that brought their reign to an end.
