1 The Mesozoic Era By: Phil Stark and Michael Sartor Earth Science, p.6 Fr. ONeill By: Phil Stark and Michael Sartor Earth Science, p.6 Fr. ONeill

2 In The Beginning FThe start of the Mesozoic Era was a desolate time in Earths history. FOver 90% of Earths life extinct. FBarren wasteland from comet, climate change, or volcanic eruptions. FCalled: Great Dying. FMeans Middle Animals FLife that survived re-populated the planet, diversified ecosystems, and gave birth to all new life FThe start of the Mesozoic Era was a desolate time in Earths history.

3 What It Was Like FEarths landmasses collided forming Pangea. FPangea was the first known super- continent. FC-shaped. FCame undone as soon as it formed. FThe split caused erratic climate everywhere. FSeasonal monsoons, global warming, and rift valley formation FFormed red sediment that best preserved fossils FEarths landmasses collided forming Pangea.

4 Life Forms FOceans were teaming with all new life: coil- shelled ammonites, mollusks, sea urchins, coral. FGiant reptiles such as the: Ichthyosaurs, the long-necked and paddle-finned plesiosaurs, and squids. FPhytoplankton first appeared. FFrogs, salamanders, crocodiles, and turtles. FPterosaurs ruled the sky. FOn the ground were: moss, liverwort, ginkgoes, palm-like cycads. FAlso on land were: spiders, scorpions, millipedes, and grasshoppers. FFirst evolutions of dinosaurs.

6 The End To A Beginning FEnded the same way it started. FAnother mass extinction FDinosaurs survived into the Jurassic though. FEnded the same way it started. FAnother mass extinction FDinosaurs survived into the Jurassic though.
