Why Did Dinosaurs Vanish From The Earth By Rachel Kooienga On Prezi The cretaceous–paleogene (k–pg) extinction event, [a] also known as the cretaceous–tertiary (k–t) extinction, [b] was the mass extinction of three quarters of the plant and animal species on earth [2][3] approximately 66 million years ago. the event caused the extinction of all non avian dinosaurs. Still a theory. the cretaceous tertiary extinction event, or the k t event, is the name given to the die off of the dinosaurs and other species that took place some 65.5 million years ago. for. A period of intense cold and darkness followed an initial heatwave, as aerosols and particulates blocked out the sun. sulfates from the atmosphere acidified the oceans. what you didn’t know about the kt extinction: researchers debate whether the asteroid strike caused or merely contributed to the die off. New research now makes the case that the same incident that helped bring an end to the reign of the dinosaurs also acidified the planet’s oceans, disrupted the food chain that sustained life.
A Vanished World The Dinosaurs Of Western Canada By Dale A Russell A period of intense cold and darkness followed an initial heatwave, as aerosols and particulates blocked out the sun. sulfates from the atmosphere acidified the oceans. what you didn’t know about the kt extinction: researchers debate whether the asteroid strike caused or merely contributed to the die off. New research now makes the case that the same incident that helped bring an end to the reign of the dinosaurs also acidified the planet’s oceans, disrupted the food chain that sustained life. 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. although the number of dinosaur species was already declining, this suggests a sudden catastrophic event sealed their fate something. Decline and fall. most importantly, we found clear evidence for a long term decline from 40m years before the end of the cretaceous period. we looked at all dinosaurs, and then each of the main.
