__The Landform And Rocks__
Similar to life, the landforms and rocks are also changing. Volcanic activity began during the Jurassic Period in East Africa, Antarctica, and Madagascar, were South Atlantic Ocean would later form. Eastern North America had highlands, but that was eroded, just as the shallow seas retreated to west coast of North America. One of the fascinating things are fossils, many of them were found during the Jurassic Period, and they are found all over the world. Fossils of the Ichthyosaurus found in England and Germany showed us that the sea life back then was similar to the ones we find today. Back then, sea animals had fins, two pairs of flippers, and a forked vertical tail, like a shark. The fossilized Barapasaurus found in India was able to demonstrate the size of a Barapasaurus and its diet, which was all plants. In 1861, they found a fossilized Compsognathus in Europe, but it was not until the 1990’s that they realized there were fossilized eggs with her. They predict she was pregnant when she died and the eggs came out after her death. The rocks of the Jurassic Period are found all over the world. Here in North America they are found in a couple of regions such as the west part of Canada, and the states east of the Appalachian Mountains. In mountains such as the Rocky Mountains or the Cascade Mountains, you can find rocks dating back to the Jurassic Period if you search deep down. The rocks and fossils are our time machines to the past, and what tells us what lived during each period.
