Paleontologists discovered the first fossils in the early 1800s, far before dinosaurs were ever discovered. This genus evolved from animals that lived on land. They had more than eighty different species in their genus. One species of the ichthyosaurs is the Ophthalmosaurus. As an adult, this creature was two times the size of a human with a tooth filled snout.…

The passage on the body temperatures of the dinosaurs dictate that dinosaurs were endothermic animals. Three reasons are being given for this arguement: existence of dinosaur fossils in polar region, the leg position of the dinosaur and the haversian canals in the bone structure of the dinosaur. The fossils that have been founded in the polar region is being classified as a clear indicator for endothermy in dinosaurs. However, the lecturer confronts this point by highlighting the climate in the…

The Eocene era is the second epoch in the Tertiary Period and lasted around 55.8 to 33.9 million years ago. In that era, the shape and location of the continents affected the general weather trends marked the Eocene epoch and affected the evolution of mammals, primates, and humans. There were some changes in the isotope content of the large marine carbon pool; they forcedly shifted into the smaller carbon pools in the atmosphere and on land. The carbon isotope compositions of marine carbonate…
