Antarctica's Fossil- Evidence of Pangaea
Transcript of Antarctica's Fossil- Evidence of Pangaea
was a Cryolophosaurus, which lived in the
Renaissance Period. Fact The First Fossils The first fossil group found in Antarctica was called the Plesiosaurs. They were a bunch of marine animals. One of the first fossils found was the Ankylosaur. It was found on James Ross Island around the year 1982. Vega Island On Vega Island, a dinosaur called a Hadrosaurs was found in 1986. It lived during the Cretaceous Period. The Hadrosaurs were land mammals that could grow as high as 20 feet. This fossil was the first duck billed dinosaur ever to be recorded and was also found on the outside edges of North and South America, which is proof that Pangaea did exist. Other wise, the Hadrosaurs could never travel and the fossils wouldn't be found in three different continents. More Fossils Other fossils found in Antarctica were flightless birds, flying birds, sharks, fish, reptiles, beetles, and snails. Also, fossilized rainforest plants were found, connected to a time when the climate was more moderate than it is today. This also proves that Pangaea did exist because Antarctica was warm back then, providing that it's location would have been more North, right about where Pangaea used to be. Antarctica must have been introduced to rainforests back when it was connected to the other continents.
So few dinosaur fossils have been found in Antarctica because the continent is 98% ice year round, making it difficult to discover the fossils buried underneath the ice.
Robert A. Sutton lead an early expedition to Antarctica and reported on seeing the very first fossils of leaves and stems of plants. Coal was first discovered in Antarctica during an expedition led by Ernest Shackleton in 1908. Coal supports the idea that Antarctica was once warmer than it is today because coal is a biochemical rock made from dead swamp and forest plants and animals. It would have had to be warm back then to have swamps and rainforests in Antarctica. Antarctica's Fossils By: Alex Rono & David Gosper An Ankylosaur Two Hadrosaurs Coal with Fossils Conclusion The fossils of Antarctica prove that Wegener's hypothesis about Pangaea is true because it has fossils that wouldn't normally be found there and had to have traveled from the other continents when it was connected to Pangaea. Pangaea did exist and is scientifically proven, fossil style, and Antarctica is the continent that holds a lot of evidence.
