-  * The Earth's sun is red at this time, possibly because of cosmic interference. ["Neverwas, the Chaos-Maker," Justice League of America #68 (December, 1968)] 
-  * Neverwas, a protoplasmic, amoeba-like being, comes into being, possessing strange powers and fearing other creatures. It somehow travels through time to the age of the pterodactyl, then ends up in the 20th century, before the Justice League of America returns it to its original era, along with a giant toy robot to keep it company.

 +  * Neverwas, a protoplasmic, amoeba-like creature who is possibly the first intelligent life to form on Earth, comes into being, possessing strange powers such as the ability to open up portals into the future or the past. At some point in its existence it travels forward in time to the age of dinosaurs. //Note: It's probable that Neverwas originally arose billions of years ago during a more primitive era, and used its powers to travel forward through time more than once to reach the dinosaur age.// ["Neverwas, the Chaos-Maker," Justice League of America #68 (December, 1968)]
 +  * Neverwas hurls a luxury beach hotel from 1978 A.D. to this era through a time portal. Superman follows after it, but loses his powers under the red sun, until Neverwas opens up another time portal that allows him to bring himself and the motel back to the 20th century, and hurl Neverwas back to his own era, after giving him a giant robot toy to keep himself too occupied to travel through time again.

-  * The Xan, a race of tall, handsome humans from another planet, establish a super-civilization on Earth, living in sky-cities built by advanced science. As expert builders of robots and androids, their crowning achievement is Eterno, a nearly 50-foot-tall half-robot, half-android constructed to live forever, energized by cosmic radiation, and given the complete knowledge of the Xan in his artificial brain. Although Eterno was incredibly wise and powerful, he planned to conquer Earth for himself. Before he could do so, a cloud of space gas drifted to Earth that the Xan knew could kill them off. Eterno traveled to the earth's core to find absorbium, the only element that could combat the space gas, but the absorbium caused Eterno to become paralyzed for a billion years until he is temporarily freed in the year 1977 AD by the Superman Revenge Squad. Meanwhile, the cloud of space gas causes Earth's largest mass extinction, the Permian-Triassic extinction event. //Note: The Xan are said to have lived about a billion years ago, but it is more likely that the mass extinction that killed them off is a known event, which must be somewhat more recent.// ["Eterno the Immortal," Action Comics #343 (November, 1966)] 
   * Permian–Triassic extinction event: Earth's largest extinction kills 57% of all families, 83% of all genera, and 90% to 96% of all species (53% of marine families, 84% of marine genera, about 96% of all marine species, and an estimated 70% of land species, including insects). The "Great Dying" has enormous evolutionary significance: on land, it ends the primacy of mammal-like reptiles. The recovery of vertebrates takes 30 million years, but the vacant niches create the opportunity for archosaurs to become ascendant. In the seas, the percentage of animals that were sessile drop from 67% to 50%. The whole late Permian is a difficult time for at least marine life, even before the "Great Dying."   * Permian–Triassic extinction event: Earth's largest extinction kills 57% of all families, 83% of all genera, and 90% to 96% of all species (53% of marine families, 84% of marine genera, about 96% of all marine species, and an estimated 70% of land species, including insects).

-  * Cretaceous–Paleogene extinction event: A meteor impact in the Yucatan, Mexico, causes a mass extinction and ending the Mesozoic Era. About 17% of all families, 50% of all genera, and 75% of all species become extinct. In the seas it reduces the percentage of sessile animals to about 33%. The majority of non-avian dinosaurs become extinct during that time. The boundary event is severe, with a significant amount of variability in the rate of extinction between and among different clades. Mammals and birds emerge as dominant land vertebrates in the age of new life. Most of the dinosaurs are killed off, with only a remnant of dinosaurs survives in hidden lands, such as Skartaris and Dinosaur Island in the Pacific Ocean. The Cenozoic Era (which lasts into the present) begins.+  * Cretaceous–Paleogene extinction event: A meteor impact in the Yucatan, Mexico, causes a mass extinction and ends the Mesozoic Era.
