Sorry, are you still waiting? The Mesozoic era (from 252 to 66 million years ago) is known as the Age of Reptiles or, for you terrestrial loving tree-huggers, the Age of the Conifers, not to mention the freaking DINOSAURS!!!!! This era is divided into only three periods (phew).

Spoiler Alert: If you want to skip the next few sections, here’s the plot summary: Early mammals, birds, amphibians, bees, and flowering plants evolved. Dinosaurs took over the planet (woohoo!), then all non-avian (not birdlike) dinosaurs went extinct (booo!). The Mesozoic marine revolution occurred, during which shell-crushing marine reptiles evolved, causing organisms with shells to grow stronger, spinier shells in self-defense, which sparked an evolutionary arms race that continues to this day.
