Life and Climate

  • Just before the Mesozoic era the Permian extinction occurred which resulted in a diversity in vertebrate life, along with the beginning of modern ecosystems on Earth.
  • The climate of the Mesozoic era was nothing to what it is today. There were no ice caps, and while there is no documentation of significant global temperature changes, there was distribution of coal which indicates patterns of humid and arid zones.

Big Events

K-T Mass Extinction, which occurred at the end of the Cretaceous Period. Nearly 75% of species living at that time were extinct. Though not the largest extinction of it’s time, it was what ultimately took out the dinosaurs. The suspected cause of this was extreme asteroid or meteor impact. This was found by scientists studying craters left by the asteroids.

Fun Facts

  • The beginning of birds originates from the theropod dinosaurs
