Discovery of the Dinosaur with the Fossilized Heart :: Exploratory Essays Research Papers

Discovery of the Dinosaur with the Fossilized HeartDinosaur fossils are genius of the few ways in which scientists can study the history of living on earth millions of age ago. Each refreshing discovery is rum in its own way and provides valuable information about the past. No two finds are exactly identical therefore, when dinosaur form are uncovered, the initiative and excitement of new information or even a new species exists. Until the year 2000, no dinosaur has ever been found with a fossilized heart. Scientists at normality Carolina State University and the North Carolina Museum of lifelike Sciences discovered a cardinal million year old Thescelosaurus with a heart.The Thescelosaurus was a bird-hipped dinosaur or an ornithischian ( Russell 2). This herbivore lived near the end of the Cretaceous period, about one million years before the conclusion of the dinosaur era. Thescelosaurus was about the size of a short-legged pony, according to paleontologist Dr. Dale Russell and was native to North America from Wyoming up to Alberta, Canada.This particular Thescelosaurus was discovered in Harding County, northwestern South Dakota in 1993. It has been estimated to weigh nearly 663 pounds and thirteen feet long. The remains were located in a poorly consolidated channel of sandstone, open in the upper half of the Hell Creek Formation (Fisher 2). Scientists countenance named this discovery Willo, after the wife of the rancher on whose property it was found. The discovery of Willo is comical because it is the first dinosaur with a fossilized heart. However, this was just the beginning of an extraordinary find. not only does this specimen pee a heart, but computer enhance images of its chest strongly suggest it is a four- put up, double-pump heart with a item-by-item systemic aorta, more like the heart of a mammal or bird than a reptile, according to Dr. Dale Russell. Russell is a paleontologist at North Carolina State University and a se nior research curator at the N.C. Museum of Natural Sciences. This discovery is unusual because all modern reptiles, except the crocodile, contain a case-by-case ventricle that pumps blood to the lungs and the rest of the body. All modern reptiles have paired systemic aortas developing from the ventricle, which distributes the blood to the body. In contrast, the four chambered heart of modern birds and mammals has two completely separated ventricles and a single systemic aorta, ensuring that only completely oxygenated blood is distributed to the body (Fisher 2).
