Paleontologists: Very Old Sea Turtles

The Tritheledont, found in rocks that, according to the law of superposition were 190 million years old, had teeth and other skin features such as scales like mammals and reptiles, respectively.

* Burgess Shale - One of the greatest fossil finds ever made is the Burgess fauna of British Columbia. Thousands of soft-bodied animal fossils paint us a picture of early marine life.

The magnificent leatherback sea turtle is a precious species that exists in the world today. It has endured and evolved through the years, and it would be terrible if humans put an end to their amazing existence. By learning more and taking an active role in supporting conservation programs, hopefully the leatherback population can grow and

The leatherback is an endangered species. It's also the largest sea turtle. Adults usually weigh about 800 to 1,000 pounds (363 to 454 kilograms). Some have been reported to weigh as much as 2,000 pounds (907 kilograms). The turtles get their name because their backs are covered with leathery, oily tissue instead of a shell.

In a study published in Cretaceous Research and conducted in October 2012 by Anthony R. Fiorillo, Thomas L. Adams and Yoshitsugu Kobayashi, evidence of dinosaurs was based on the finding of an unnamed nonmarine sedimentary package of rocks. Found in the Wrangellia Terrane and considered to be Cretaceous age, the rocks are light colored with medium grey shales and indicate a bounty of horsetails, ferns and gymnosperm wood.

The Ocean is 70 percent of the earth’s surface, humans have explored less than five percent of the ocean, and is home to an innumerable amount of living organisms. One of its oldest inhabitants is the Cheloniidae dates back to the Triassic era, roughly 250 million years ago, (Wang et al., 2013). The Cheloniidae family has several subspecies the Eretmochelys imbricate, Caretta caretta, Dermochelys coriacea, Lepidochelys olivacea, and Chelonia mydas. While there are multiple endangered subspecies of the Cheloniidae; the endangered Chelonia mydas, commonly known as the green turtle, will be the focus of this paper. The paper will discuss the green turtle’s importance to its ecosystem, where they are most commonly found, importance to its ecosystem,

The Blanding turtle are freshwater medium sized turtle usually found in The Great Lakes Regions in USA and in Canada. They are from the omnivorous species and usually eat crayfish, small animals, and plants. Their life histories traits occurs between April and November, as May and April tend to be more for mating and Early June for nesting. Less than half of these females will actually go on to reproducing. Many of these turtles can actually live up to sixty to a hundred years in age. Though these turtles spend a majority of time in the aquatics they also come on to the mainland. This is were the problem starts to occur and this is why the Blanding sea turtles are currently threatened and may soon be extinct. It is because of us humans that these species are currently facing habitat loss, have threatened nesting areas, and are unable to get from nesting areas to the lakes because of manmade roads. Why should we as humans care so much if these Blanding’s turtles go extinct? These turtles play an important

Sea turtles are becoming more and more endangered as time goes on and is something that really needs to be changed. There are seven species of sea turtle and they are all either endangered or critically endangered. Millions of sea turtles used to inhabit the sea now only a fraction of them are still around. Humans are partly the cause of this because we hunt them for food and profit. It is unbelievable that people can kill such beautiful creatures just for their personal benefit. Humans are not the only reason sea turtles are facing extinction, but we are the main reason. Humans really should not be part of the problem in the first place.

Turtles have been on this earth for more than 200 million years. They evolved before mammals, birds, crocodiles, snakes and even lizards. The earliest turtles had teeth and could not retract their heads, but other than this, modern turtles are very similar to their ancestors. Several species of turtle can live to be over a hundred years old, including the American Box Turtle.

often will people think of a nautilus, an organism that is a distant cousin of cuttlefish and squid. These organisms have been dubbed "living fossils" and have been on earth for about 500 million years. The nautilus tends to in front of coral reefs, deep in the ocean. The long existence of the nautilus has allowed its mesmerizing spiral shell to be embedded in some rocks and has become a part of the fossil record.

I found on the website http://nationalgeographic.org/media/pterodactyl-fossil/, that the pterodactyl had been living in about the Jurassic period or 150 million years ago.

The article that I chose for this assignment is about the recent discovery/confirmation of the first known dinosaur which lived and thrived in the water. The Spinosaurus aegyptiacus was found and collected by Dr. Nizar Ibrahim from the University of Chicago. Ibrahim along with his colleague Dr. Paul Sereno determined that based on the fossil discovered that the specimen was a swimming dinosaur. Technically, the bones of Spinosaurs were first discovered 100 years ago by a German paleontologist in Egypt. However, these bones were only a sample of the full skeleton and they were stored in a museum in Munich, Germany which was later bombed by the Allies during World War II; thus

Sea turtles have been a big help in maintaining the health of the world's ocean for more than 100 million years. They help by keeping up coral reefs all the way to transporting nutrients to beaches. Major changes have occurred in oceans everywhere due to the decline of the sea turtle population. Oceans are unhealthy because of this. It is time for us to protect the sea turtles and rebuild their population to ensure healthy oceans in the future. According to oceana.org, there are seven species of sea turtles that roam the world, six of which inhabit U.S. waters, and have been listed as either endangered, or threatened. Up until now, all six of these species are not at a healthy level despite protection measures from the Endangered Species Act (ESA). Some populations even continue to decline. Even at a diminished population, sea turtles play an important role in ecosystems. They are also extremely important to humans because they keep oceans healthy, and we use the ocean as a food source. They keep up the health of the ocean in many different ways, all of which, are very important.

Heron Island, located on the southern end of the Great Barrier Reef, just on the Tropic of Capricorn is the breeding ground for two of the world’s largest populations of green sea turtles and loggerhead sea turtles. The green turtle is also known as the Chelonia mydas, green turtle, black turtle, or the Pacific sea turtle. This particular species of turtle is found in the Cheloniidae family. 60,000 and more female Chelonia mydas turtles swim thousands of kilometres from their feeding grounds in Indonesia, Papua New Guinea, the Torres Strait and the West Pacific, to this family sized island to lay their eggs. The loggerhead sea turtle in other words known as the Coretta Coretta, is an oceanic turtle distributed throughout the world. It is a

Save the green sea turtle (Chelonia mydas)! The green turtle is one of the largest sea turtles and the only herbivore among the different species. Contrary to popular belief green turtles are named so because of the greenish color of their cartilage and fat, not their shells. They are mainly found in tropical and subtropical waters. Green turtles are generally found in fairly shallow waters (except when migrating) inside reefs, bays, and inlets. The turtles are attracted to lagoons and shoals with an abundance of marine grass and algae. Open beaches with a sloping platform and minimal disturbance are required for nesting. The green sea turtle grows to a maximum size of about 4 feet and a weight of 440 pounds. It has a heart-shaped shell, small
