The video Dawn of Humanity is an interesting lesson about trying to bridge that gap between the Australopiths and homo genus. They briefly talk about previous finds such as Lucy and the different characteristics of Australopiths and homos. We watch how Professor Lee Berger worked with a group of scientist and climbers to explore a cave system that held thousands of bone fragments. Two cave climbers Steve and Rick were the ones who originally found the bones and took photos of them to show their friend

Quetzalcoatlus northropi is an azhdarchid pterosaur known from the Late Cretaceous of North America and one of the largest known flying animals of all time. It was a member of the Azhdarchidae‚ a family of advanced toothless pterosaurs with unusually long‚ stiffened necks. The Quetzalcoatlus was first discovered in Texas in 1971 by geology graduate student Douglas A. Lawson. The feeding habits of Quetzalcoatlus are controversial. Originally‚ it was assumed to catch fish and crustaceans‚ like most

Dinosaur Energy Ever since the discovery of the first dinosaur in 1824‚ scientists and laymen alike have been fascinated by the lives of these awe-inspiring prehistoric reptiles. How did they live? What were their insides like? How fast did they go? At the heart of these and many other such questions about these “terrible lizards” is the main controversy: were dinosaurs warm or cold-blooded? This complex scientific issue relates deeply to understanding the biology and lifestyles of these creatures

Argument 1 I believe that there may of been dinosaurs in my backyard because where my house sits at this time it was under water thousands of years ago so there would of been water type dinosaurs. When i go to the beach there are fossils from water dinosaurs in the rocks on the cliff face so that shows that there was dinosaurs in the area. because my house would have been under water there would be fossils like the ones on the beach. Any single person can go to the beach and see rocks that have bones

Diplodocus is the longest and in fact the largest known to science terrestrial dinosaurs whose complete skeletons have ever been found. In appearance‚ it resembled a lizard brontosaurus‚ but Diplodocus differed from it by a thin S-shaped neck and a long tail with a thin shout end. The first remains of Diplodocus‚ in particular its tail and hind limb bones‚ were discovered in 1877 by Samuel Williston near the town of Canyon City‚ Colorado‚ USA. According to him‚ Otniel Charles Marsh described the

Paleological evidence for homoeothermic tendencies in theropod dinosaurs in the Cretaceous Period Abstract Dinosaurs were considered to be cold blooded reptiles until several shocking discoveries and studies have changed the way that the general public has viewed them. Theropod dinosaurs have been selected to be analyzed because they have the strongest evidence pointing to warm blooded tendencies across the class. Carbon and oxygen isotopes in teeth enamel and physical fossilized data can be used

Rise of the Animals: Triumph of the Vertebrates The new frontier for fossil discoveries is China. Here Scientist are able to take evidence for evolutionary theories. The fossil record contains many well-documented examples of the transition from one species into another‚ as well as the origin of new physical features. Evidence from the fossil record is unique‚ because it provides a time perspective for understanding the evolution of life on Earth. David Attenborough embarks on an epic 500-million-year

225 million years ago‚ dinosaurs ruled the Earth. Raptors‚ such as the Velociraptor‚ made known by Jurassic Park‚ were one species of the many dinosaurs that roamed the Earth. Through many films‚ these creatures are portrayed as intelligent‚ savage beasts. However‚ studies may have proved these films wrong. They have shown that there are more types of raptors than the Velociraptor‚ different ways that they hunted their prey‚ and if and how they were able to communicate. Scientists have shown that

He explained that the stone tooth shaped fragments he had found were from an ancient shark and had been fossilized by horizontal deposits of sediment. (Circa
