Implications of the Dinosaur Heart DiscoveryThe phrase from Science News, tattler Dino Heart Hints at Warm Blood, by Tina Hesman and the Journal article it was based on from Science, Cardiovascular Evidence for an Intermediate or high Metabolic Rate in an Ornithischian Dinosaur, by Paul fisher and others both offer a new perspective on the head to be discussed, however there atomic number 18 some key differences amongst the two articles. How the two articles differ will be discussed later on in the paper. Both of the articles discuss the finding of a heart in a dinosaur that when studied challenges a common belief most dinosaurs hearts. straightway here is some background information on the dinosaur that is causing this waken because of its heart. The dinosaur is a Thescelosaurus, which means wonderful lizard. The average length of the Thescelosaurus is three to quaternion meters, nine to twelve feet, long with an average weight of three-hundred kilograms, or about six hundred and sixty two pounds. They lived from the Campanian age to Maastrichtian age which are the later stages of the Cretaceous period. Another distinguishing physical feature of Willo is the bird-hips that the dinosaur has instead of the lizard hip. They have primarily been found in Alberta, Saskatchewan, Colorado, Montana, South Dakota, and Wyoming. As farther as their remains are concerned there is one release skeleton, eight partial skeletons, elements, and teeth (Dinosauricon). Dinosaurs are often compared to and resemble late day reptiles. Scientists will study how these current day reptiles behave, look, act, and move to retire conclusions on how the dinosaurs would behave, look, act, and move. They also look at the intern make-up of the modern reptiles to predict how the dinosaurs internal make up would be. However, a recent uncovering in South Dakota is stirring up some controversy (Hesman). slice Mike Hammer was walking around a ranch in South Dako ta he stumbled across a big-eyed dinosaur that he now refers to as Willo. The thing that caught his eye was the chest cavity of the dinosaur, upon further investigation he found a rock that was preserved in the curve of the dinosaurs ribs, he was convinced that this rock was once a heart. Hammer whence went on to take the dinosaur fossil in for a medical roentgenogram scan, this X-ray showed evidence that could change how we think about dinosaurs.
