Transcript of The Future is Wild Project

The Evolution of Turtles Sea turtles are one of Earths oldest creatures. They have been around for about 245 million years. Modern Day Turtles eat things such as jellyfish, seaweed, crabs, shrimp, sponges, snails, algae and mollusks. Ancient Turtles Evidence shows that the first turtles did not have a shell. Their first relative was a a late Permian reptile whose wide, elongated ribs curved over its back. This was the beginning of the today's turtle shell. This turtle was alive around 300-250 million years ago in the Permian Period and the beginning of the Triassic Period. During this time the climate was considerable dry and arid. The next turtles were seen during the Mesozoic and Cenozoic Eras about 200 million years ago. These turtles were very different than the ones seen earlier. They were gigantic, the turtles called Archelon and Prtostega were about ten feet long and weighed up to two tons. They looked like modern day turtles just huge. They lives in the Oceans of North America and ate mostly squids and jellyfish. The New Ice Age A Warming Trend Pangea II Adaptions for the Ice Age
1. Turtle has fur in and around shell for warmth
2. Turtle has larger feet for walking in snow
3. Turtle has a tougher shell to break ice
4. Turtle is smaller to fit into small cracks in the ice for protection from predators. Adaptions for the Warming Trend
1. Turtles lose shell to move quicker from predators and keep cooler in the heat
2. Turtles grow a longer tail to keep balance because they run and walk and no longer swim
3. Turtles grow longer legs to run faster from predators
4. Turtles turn more of a brown color to blend in with their environment to camloflage themselves from predators Adaptions for Pangea II
1. Turtles grow a shell for protection from predators.
2. Turtles' shell is flexible to move with their body.
3. Turtles grow sharp nails for protection and to hunt and eat prey.
4. Turtles grow a spiky, venomous tail for protection and to help hunt. Work Cited
