Jurassic Period By: Taylor Conduff

Plants! Ferns is the most important plant in the Jurassic time. But gymnosperms (naked- seeds) dominated the terrestrial ecosystem. The seed-fern floras, such as Glossopteris of Gondwana, disappeared at or near the Triassic Jurassic boundary. Gymnosperms originated in the Paleozoic Era include three groups: cycads, cycadeoids, conifers, and ginkgos. All have exposed seeds and rely on wind dispersal for reproduction.

Animals! There is Herbivores, Carnivores, and Omnivores. Herbivores only eat plants. Carnivores only eat meat. Omnivores mostly eats everything.

Major Events! The Triassic– Jurassic extinction event marks the boundary between the Triassic and Jurassic periods, million years ago, and is one of the major extinction event of the Phanerozic eon, profoundly affecting life on land and in the oceans.

Climates! By the Middle and Late Jurassic, enough plate movement had occurred to separate South America from southern Africa Laurasia (which consisted of North America and Eurasia) also moved away from Africa and South America, helping to create the Atlantic Ocean and the Gulf of Mexico. Volcanic activity was common along these rifting continental margins. At the same time, Eurasia (Europe and Asia) moved to the south. Sea level gradually rose during the Jurassic, creating epicontinental seaways in North America and Europe. The end result was a world with many more separate land-masses, and a great deal more coastline, than the world of the Triassic.
