Mr. Mysteries' So-True Histories Episode 8 - Mesozoic Era

Hello Eager Learners! I am Mr. Mysteries, formerly of the Learned League, and this is my KARENcast series on the history of our Reality, Reality 69.
  Our last episode ending with the Great Dying, but today, just like the early proto-dinosaurs of the early Triassic, we continue to push on into the Mesozoic Era.
  The Mesozoic Era, also called the Age of Reptiles and the Age of Conifers, is the second-to-last era of Earth's geological history, lasting from about 252 to 66 million years ago and comprising the Triassic, Jurassic and Cretaceous Periods.
  <A very long monologue follows detailing the rise of the Dinosaurs and spread of great conifer forests and ending with the K-Pg extinction event.>
