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. What is difference between meteors and meteorites Class 8? 31 How did snakes survive the dinosaur extinction? When a six mile-wide asteroid struck the Earth 66 million years ago, it was one of the worst days in the history of the planet. About 75 percent of the known species were rapidly driven to extinction, including the non-avian dinosaurs like Tyrannosaurus, the flying pterosaurs, the coil-shelled squid cousins called ammonites, and many more. After examining an up-to-date fossil record, scientists believe that had the asteroid collision that fuelled their demise happened a little earlier or later, they may have been able to survive. Fish fossils appear in strata after about 500-600 My ago; dinosaurs and giant reptiles were on the land by 200 My ago. 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 extinction of the dinosaurs 66 million years ago would have benefited another animal species: snakes. Birds. Bird-like dinosaurs with toothless beaks survived the "nuclear winter" that followed the meteor strike, because of their diet, a study says. Plants die quickly without sunlight, but Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Earth froze about 466 million years ago, long before dinosaurs existed. End of an era: how long did it take the dinosaurs to die out? The argument for a simulation can seem attractive, at least on its face . New fossil evidence suggests some dinosaurs survived for up to half a million years after the impact in remote parts of New Mexico and Colorado. They were lizardlike reptiles . About 466 million years ago, long before the age of the dinosaurs, the Earth froze. It was originally thought that the debris in the atmosphere caused a “nuclear winter”, which slowly killed off all plant life, which then starved the herbivores, which later starved the carnivores. With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 pounds) survived. The second period was the Jurassic Period, which spanned from 201.3 Mya to 145 Mya. The latest theory is that dinosaurs with beaks were able to stay fed on seeds during that nuclear winter. In any case, this is revealed by a recent study from the University of Bath, published in the scientific journal Nature Communications.

The best survival games available on the PlayStation 4 platform. He came up with a strange theory to prove that all the dinosaurs were killed off by the collision of an asteroid with the surface of the earth about 65 million years ago.Asteroids contain about 100, 000 times more iridium than the layers of rock discovered by Alvarez that date back to 65 million years ago. An asteroid collided with Earth 66 million years ago in a cataclysmic event that wiped out the dinosaurs and many other creatures. 27 Did crocodiles live with dinosaurs? Impactor diameter: 11–81 kilometers (6.8–50.3 mi) Where did the chicxulub asteroid come from? Geologists and palaeontologists alike have agreed that the extinction, possibly the greatest in earth’s history, lasted over 15 million years which is hard to comprehend.
