- The Mesozoic Era is the second-to-last era of Earth’s geological history, lasting from about 252 to 66 million years ago, comprising the Triassic, Jurassic and Cretaceous Periods. It is characterized by the dominance of archosaurian reptiles, such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic.
- Eastman memos (Wikipedia)
The Eastman memos, also known as the “coup memo”, are documents by John Eastman, an American law professor retained by then-President Donald Trump, advancing the fringe legal theory that a U.S. Vice President has unilateral authority to reject certified state electors. This would have the effect of nullifying an election in order to produce an outcome personally desired by the Vice President, such as a result in the Vice President’s own party’s favor, including retaining himself as Vice President, or if the Vice President is himself the presidential candidate, then to unilaterally make himself president.
- Cretaceous–Paleogene extinction event (Wikipedia)
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 event caused the extinction of all non-avian dinosaurs. Most other tetrapods weighing more than 25 kilograms (55 pounds) also became extinct, with the exception of some ectothermic species such as sea turtles and crocodilians. It marked the end of the Cretaceous period, and with it the Mesozoic era, while heralding the beginning of the Cenozoic era, which continues to this day.
