Favorite 3 Peer Projects

One of my favorite projects that my peers presented was “ Titanoboa: The Amazonian Monster.” I had no idea that a species such as the titanoboa actually existed and it was great to learn about it. The Titanoboa was a prehistoric snake and the largest to have ever roamed the earth.  It stretched over 49 feet long and would weigh slightly over a ton. Its living relative today, the boa constrictor, isn't anywhere near the titanoboa size. The snake lived during the geologic epoch of paleocene and its remains were discovered by group of workers who stumbled upon it as they were mining for coal.
Another one of my favorite projects is "The Cotton Castle" which is an astonishing natural rock formation. I learned over how the site is a sedimentary rock formation and is made of limestone. That the water that flows down from the springs contains hydro carbonate and calcium. I also learned that the water from the spring cools as tectonic movement expose it to carbon dioxide. I also learned that the sites, also known as a travertine, lead to the release of carbon dioxide and monoxide which later results in the precipitation of calcium carbonate. Lastly if i would like to visit this mysterious and natural site i would either have to go to Turkey or Italy.
And finally the last peer presentation that I found to be my favorite was the “Megalodon” presentation. The megalodon was the largest species of shark to have ever lived. It was named after their teeth which would translate into ragged tooth. It went extinct around 1.5 million years ago. It would eat whales, carrion, dolphins , and giant sea turtles. It is not known exactly why they went extinct but a theory is that they were forced by extensive competition.

Tiger Fossil


tigerskeleton1-e1327988084470.jpg Our project is basically over the fossils of tigers (some prehistoric cats and cat like mammals).  Within the project we wrote over import information relating to the fossil such as the age of the some of fossils signaling the tigers very first appearances. The project also holds some facts such as how a common misconception is that Sabretooth's were actual tigers. They are in fact their own their species of prehistoric cat called Smilodon Fatalis which went into extinction around 10,000 years ago. We stated how with the fossils and remains migration of the tiger is seen as it spread through the different continents over time. And with this as their environment would change many cat-like species, including tigers, were forced to adapt. The differences in the bone structures of the tiger have not changed much since the beginning of the prehistoric cat.  Some only small changes occurred in the Tigers have lost their big teeth during their evolution into now being much smaller.The size of the tigers back then were actually a lot smaller than what they are now. As time progressed migration occurred they grew in size as opposed to how their prehistoric counterparts were. They are now reaching up to 13 feet (4 meters) in length, including its tail, and weighing up to 660 pounds (300 kilograms).
