The Importance of Dinosaur Discoveries
When a paleontologist makes a discovery about Dinosaurs it is usually a celebrated event and will appear on all sorts of covers of magazines and even newspapers, with good reason. These discoveries are often quite exciting for a few reasons. The whole experience of finding a fossil that is hundreds of millions of years old is quite an adrenaline rush, but the fact that each discovery has the ability to answer questions in relation to evolution is quite amazing. Each finding of Dinosaur remains can help answer questions of how that certain species evolved from another. If our species can fully understand how Dinosaurs evolved, maybe in the future we can learn something about our evolution. Without discoveries from the past how is our society supposed to persevere and learn from mistakes that may lead to our own extinction, and who to learn better from than perhaps the dinosaurs that have gone through many stages of evolution and have faced extinction.
The finding that will be discussed is the discovery of a new type of long- necked Sauropod Dinosaur named Rapetosauras, in the country of Madagascar (National Science Foundation). It was found by two groups of scientists. One group was headed up by Dr. Catherine Forster of SUNY Stony Brook and the other was led by Dr. Curry Rogers of the Science Museum of Minnesota (National Science Foundation). The paleontologists in total found a skeleton that possessed a set of 80 to 90 vertebrate from the neck all the way down to the tail (National Geographic). The two teams also discovered two nearly complete skulls, one from a young Rapetosauras and another from an adult (National Geographic). The Rapetosauras is a type of Dinosaur called a Titanosaur, which is a member of the Sauropod group. This dinosaur was pretty common in the Southern Hemisphere and has been found in different parts of the world (National Science Foundation). There are thirty types Titanosaurs know to Paleontologists, but there has never been anyway to link them all together.
These Dinosaur remains proved to be the key in showing a correlation that could have only been dreamed of. The discovery showed that Titanosaurs and Brachiosaurs are closely related (National Science Foundation).Tyrannosaurs and Brachiosaurs are both species of Sauropod Dinosaurs. These Dinosaurs were both labeled as dominant herbivores of their times. Both were also extremely large Dinosaurs. Tyrannosaurs ranged from being 4 to 25 meters long (Titanosauria) and Brachiosaurs were roughly the same size, on average they were 26 meters long, with 12 of those meters accounting for its neck (Brachiosaurus). Both Dinosaurs also were known for having four legs. So it would seem logical for a person to believe that these two species are related, but nothing is for certain until proven as fact. Up to this point the there was no true evidence for a person to tell that Titanosaurs and Brachiosaurs are related to each other...
