What was the result of the Cretaceous extinction?
K–T extinction, abbreviation of Cretaceous–Tertiary extinction, also called K–Pg extinction or Cretaceous–Paleogene extinction, a global extinction event responsible for eliminating approximately 80 percent of all species of animals at or very close to the boundary between the Cretaceous and Paleogene periods, about 66 …
What happened at the end of the Cretaceous?
At the end of the Cretaceous Period, 65 million years ago, an asteroid hit Earth in the Yucatan Peninsula, Mexico, forming what is today called the Chicxulub impact crater. Whatever its cause, this extinction event marks the end of the Cretaceous Period and of the Mesozoic Era.
What died during the Cretaceous-Tertiary extinction?
In the oceans, the K–Pg extinction killed off plesiosaurs and mosasaurs and devastated teleost fish, sharks, mollusks (especially ammonites, which became extinct), and many species of plankton.

On the land it most famously exterminated the dinosaurs and so made it possible for mammals to become the dominant land vertebrates – and hence paved the way for human evolution.
Why was dinosaurs Cancelled?
On top of the declining ratings, one of the biggest reasons that Dinosaurs met cancellation after its fourth season was the series’ unbelievably costly budget.
Where did dinosaurs go extinct?
The theory gained even more steam when scientists were able to link the extinction event to a huge impact crater along the coast of Mexico’s Yucatán Peninsula. At about 93 miles wide, the Chicxulub crater seems to be the right size and age to account for the dino die-off.
How did Dinosaur born?
As far as we know, all dinosaurs reproduced by laying eggs, as do most other sauropsids (reptiles). It is very difficult to determine what species of dinosaur laid the eggs that have been discovered, because only a few dinosaur embryos have been found inside the fossil eggs.
