Event Synopsis

The Cretaceous–Paleogene Extinction Event, also known as the Cretaceous–Tertiary Extinction, was a sudden mass extinction of some three-quarters of the plant and animal species on Earth, approximately 66 million years ago.[1]


The larger dinosaur species were wiped out.The small mammals having escaped the chaos could evolve and take new forms. This allowed the human race the opportunity to evolve.[2][3]

Many of the Dinosaurs were taken by the Nuwali to a sanctuary on the southern continent know as the Savage Land.[4]

Alternate theories and claims

A number of alternative theories exist surrounding that event:

  • One theory included a meteor or asteroid collided with the Earth.[5][6] That meteor has been stated itself to have multiple origins:
    • The asteroid had been drawn from space by the planet itself, as a mean to crack open the Superflow, in order to initiate its first White Event on Earth. The Starbrand housed in the asteroid created a new Starbrand Protector from a Dinosaur.[1]
    • When an ancient world was destroyed, it formed fragments that became the meteor that hit the Earth. The fragments later became known as the Time Diamonds.[7]
    • During the forging of Mjolnir, large meteors were sent colliding with Midgard (Earth) causing the dinosaurs death and making room for other species.[3]
  • Other theories assume that the extinction of the Dinosaurs was the result of an evolutionary dead end (possibly due a sentient being's choice):
    • Reed Richards came up with a theory that the dinosaurs went extinct due to their large bodies and small brains.[8]
    • Gaea, also known as Mother Earth, decided that dinosaurs were at a evolutionary dead and wanted to prepare for the age of Mammals. The evil god Set wanted to keep the world as it was which lead to a battle with Demogorge. The aftermatch lead to the destruction of the dinosaurs.[2]
    • It was revealed That Which Endures, a collective entity responsible for natural selection, decided dinosaurs were a evolutionary dead end and chose to focus on mammals.[9]
  • Finally, other theories state that the extinction was caused by a sentient being, out of evolutionary concerns:
    • Loki claimed that the last time Ratatoskr was loose, "all the raptors got replaced by hairless apes who invented fax machines."[10]
    • A "primal scream" caused by a cosmic being who was humorlessly described as getting "his knickers in a twist" was also a cause.[11]

Alternative Realities


Earth-9997's past suggests that the dinosaurs were wiped out when the Celestials carved out a portion of the Moon to serve as orbiting observatory for the Watcher.[12] This reality also has its own version of Devil Dinosaur.[13]
