Cretaceous-Tertiary Mass Extinction
Evolutionary biologists and geologists generally believe that a mass extinction of dinosaurs and other organisms happened 65 million years ago, the fifth mass extinction listed in geological history, at the end of the Cretaceous Period. Its primary cause is generally believed to be an asteroid or comet impact, linked to the Chicxulub crater off the Yucatán Peninsula of Mexico, resulting in the extinction of 70% of all life on Earth.
Some creation scientists believe that virtually the entire geologic record within which fossils, including dinosaur fossils, are found were laid down during the Flood or its immediate aftermath, thus there was no K/T event. Every dinosaur kind was created by God during creation week approximately 6,000 years ago, and Noah may have taken dinosaurs with him on the Ark.
