Feathered dinosaurs

160 million years, the terrestrial environment was dominated by dinosaurs. Dinosaurs arose from fully bipedal ancestors, who is believed to have been a carnivore or omnivore (Langer, Ezcurra, Bittencourt & Novas, 2010). These agile terrestrial archosaurs lived during the Late Permian and Early Triassic and had already developed key changes in the hips and ankles that set the stage for the increase in body size that is seen in dinosaurs (Pough, Janis & Heiser, 2013). This included an alteration…

lizard”), a four-legged dinosaur in 1879. With at least three known species, this dinosaur lived in the Morrison Formation of present day Western US, during the late Jurassic Period and became extinct by the end of the period. Perhaps one of the most controversially classified dinosaurs, paleontologists have reclassified the Brontosaurus several times since its discovery to an extent that some quarters believed that it did not exist entirely. As one of the most known dinosaurs, it continues to…

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 polar region when…

Five extinctions of Earth and Who will be Next? The Earth we live on now is drastically different from how it was millions of years ago. The Earth has gone through many changes and events though time. There are five major events in history that have changed the world. Without these five mass extinctions who knows what Earth would have looked like, and if humans would even be alive. In the ordovician period 439 million years ago there was a mass extinction that wiped out 89% of life on Earth.…

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…

The first chapter in the sixth extinction is geared towards focusing on the rapid extinction of frogs, a species that has survived over 400 million years. Elizabeth Kolbert, the author believes that we are entering a sixth extinction and that it is crucial to pay close attention to it because any slight change can drastically influence an entire ecosystem and its inhabitants. The epicenter of the extinction seemed to begin in a small town in Central Panama called El Valle de Anton. The…

Did you know that dinosaurs roamed the Earth for over 165 million years? Did you know that the dinosaur with the longest name is Micropachycephalosaurus? To Max, these are facts that come as naturally as the score for the biggest football game this weekend. Max’s favorite t-shirt has a bright red Tyrannosaurus Rex on the front and he sports it proudly once a week- always on a Tuesday. Sometimes the kids at school pick on him for his unique interests and his lack of social skills. Some of the…

sized (compared to it’s close relatives) theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period. Like other abelisaurids (members of the family Abelisauridae) , the Majungasaurus was a two-footed predator with a short snout. Although the forelimbs are not completely known as of yet, they were very short, while the hind limbs were longer and quite stocky. It can be distinguished from other dinosaurs in it’s family by its wider skull, the…

vanishing since the start of life on our planet. Truth be told, most species that have ever lived on Earth are presently wiped out or never again living. Right around 50 percent of plant species and 75 percent of creature species, including the dinosaurs, wound up terminated. Species are constantly vanishing. This is the aftereffect of infections, rivalry from different species or the regular change in their atmosphere. At the point when people turned into the most capable species, the…

The largest dinosaurs to walk the Earth may have embarked on seasonal migrations that covered hundreds of kilometres when local watering holes dried up and food became scarce. Evidence that giant sauropods set off on epic journeys came to light when scientists examined fossilised teeth recovered from the remains of beasts unearthed in Wyoming and Utah in the US. The analysis of 32 teeth belonging to two species of Camarasaurus, among the most common sauropods found in North America, suggests…
