2 In The BeginningThe start of the Mesozoic Era was a desolate time in Earth’s history.Over 90% of Earth’s life extinct.Barren wasteland from comet, climate change, or volcanic eruptions.Called: Great Dying.Means “Middle Animals”Life that survived re-populated the planet, diversified ecosystems, and gave birth to all new life
3 What It Was Like Earth’s landmasses collided forming Pangea. Pangea was the first known super-continent.C-shaped.Came undone as soon as it formed.The split caused erratic climate everywhere.Seasonal monsoons, global warming, and rift valley formationFormed red sediment that best preserved fossils
4 Life FormsOceans were teaming with all new life: coil-shelled ammonites, mollusks, sea urchins, coral.Giant reptiles such as the: Ichthyosaurs, the long-necked and paddle-finned plesiosaurs, and squids.Phytoplankton first appeared.Frogs, salamanders, crocodiles, and turtles.Pterosaurs ruled the sky.On the ground were: moss, liverwort, ginkgoes, palm-like cycads.Also on land were: spiders, scorpions, millipedes, and grasshoppers.First evolutions of dinosaurs.
