Fossils And Paleontology

974 Words4 Pages

What are fossils? “Fossils are the remains or impression of a prehistoric organism or object preserved in petrified form or as a mold or cast in a rock,” according to Encyclopedia.com. Some examples of fossils are a mold of a seashell in a rock or maybe the remains of a dinosaur such a tyrannosaurus rex. A mold of a seashell in a rock may not seem all that exciting, but it can tell us a whole lot about the past. Simply put, through fossils we get see what species existed on earth and when they existed. For instance, if a fossil of an animal were to be found it would be closely studied and compared to other known species with the use of a dichotomous key, scientific processes, and the six kingdom system.

In the times of BC records were not as avidly kept. As a result history of paleontology does not become much clearer until even more recent times. Fun fact the word paleontology was not even invented until 1822 by the editor of a scientific journal whose name is unknown. The timeline of fossils is much more accurate with all the advanced technology of the 21st century. Dating techniques used by scientist become more and more accurate the more they are developed. In fact they’ve even discovered that the oldest known fossils are cyanobacteria from ancient rocks in Australia dating 3.5 billion years old! Cyanobacteria is a phylum of bacteria that get their energy through photosynthesis much like plants. To compare, the existence of the Homo genus only goes as far back as 2.8 million years, a theory supported by the remains of a jaw similar to that of a human. The Homo genus in definition is “a genus of primates that includes modern humans (Homo sapiens) and several extinct species” . A genus is “a class of things that have common characteristics and that can be divided into subordinate kinds”. A historical fossil find and honorable mention is the Burgess Shale. The Burgess Shale is a fossil deposit in the Canadian Rockies. It was found by the paleontologist Charles Walcott on August 8th, 1909. He had found more than 65,000 organisms in the Burgess Shale before his death at the age of

Riversleigh Fossil Site, Australia Geological History Riversleigh covers an area of approximately 80 square kilometres and is located 250 km north-west of Mt Isa. Riversleigh is Australia’s most famous fossil site and fossils were first discovered in the area in 1901. The fossils document the evolution and changes of Australia's terrestrial fauna and ecosystems.

There have been experimental pits dug around the tomb but the tomb itself has never been excavated. By looking at the Roman Catacombs, it is seen that the past influences modern day activities. Relative dating does not provide actual dates for objects, although it can be used to arrange geological events. Through looking at strata it is able to look at timeline events and arrange them chronologically.

Neil chose to look in sedimentary rocks, such as limestone, sandstones, siltstones and shales, because they form fossils gently since they generally are formed by rivers, lakes and seas. At first, they were looking for fossils in the Devonian rocks in Pennsylvania, but they did not have much luck since the rocks had too much exposure. So they found that the High Arctic of Canada was ideal because the rocks were 375 million years old, they were sedimentary and had little exposure. Webbed fins, a flat head, a neck and scales on its

The fossil finding process is long and hard, it can take years before something life changing is discovered. Neil Shubin knows all about this as it took him and his team years of searching to find one of the most important fossils that tell about evolution, the Tiktaalik. Early on in the book Neil asks us “How can we visualize events that happened millions

Geologists have found that the oldest exposed rocks in the national park to date back to 75 million years. The formations resulted from sediments that were largely swept into the area due to the rise of the Rocky Mountains. This eventually resulted in a rising of land above sea level. The deposits consisted of different strata of dark shale beds, many containing fossils of marine life from the Seaway (Stoffer 2003).

It was a hominin molar. The team look through that area, and found the lower jaw of a child with an attached milk molar. The team knew that the molar they found was of a hominin both older and more primitive than Lucy. In November 1994, Yohannes Haile-Selassie found pieces of a bone from the palm of a hand. That discovery was followed by the finding of pieces of a pelvis, leg, ankle, and foot bones, many of the bones of the hand and arm, a lower jaw with teeth, and a cranium (Gibbons 37).

The bones are being studied by paleontologists at Cerro Ballena, or “Whale Hill,” in the Atacama region of Chile close to the Pan-American Highway. This particular area is nearly 120 feet above sea level and nowhere near an ocean, which makes the discovery even more unique. Experts believe that the skeletons

While digging a tunnel around the left scapula, Brooks encountered a hard object which he removed and it was identified as a fluted artifact. This was a major discovery as it was believed to be the first association between a fluted artifact and a mammoth skeleton. Controversy began when two scientists claimed that the land where the mammoth was found was far too old for a fluted artifact to be in play. Many scientists had taken position that the angus mammoth and the fluted artifact were a good association however there were the few skeptics who continued to look for and argue that the site was too old and therefore impossible to validate the discovery. Henry F. Osborne, a leading paleontologist, believed this finding represented the mammoth’s migration to North America from the Old world.

The Piltdown fossils man was the missing link between apes and humans found in 1911 and 1912. The fossils included a portion of the skull, a jawbone and a few teeth. The relics were said to be found in Piltdown, England by workers digging a pit. The scientist discovered that the jaw and teeth were not the same age as the skull and were not even fossils, just old

When reading in chapter 9 about “Geology and Primate Origins”, I came to a decision to choose the relative dating techniques. It is dating techniques that establish the age of a fossil only in comparison to other materials found above and below it. Relative dating techniques use the principles of stratigraphy to tell us how old something is in relation to something else without applying an actual chronological age. An example of this technique is biostratigraphy (faunal correlation), biostratigraphy is a relative dating technique using the comparison of fossils from different stratigraphic sequences to estimate which layers are older and which are younger; employed in the Early Pleistocene deposits at Olduvai and other African sites. The prime

Endless theories and hypothesis’ surround the disappearance of the dinosaur species. Comets, asteroids, disease, and volcanic eruptions are just some of the presumed causes of their extinction. Which one is to believe? In “Sex, Drugs, Disaster, and the Extinction of Dinosaurs,” Stephen Jay Gould presents three proposals for their extinction: Sex, Drugs, and Disasters. Gould explains the three theories on the extinction of dinosaurs by giving a biologic and scientific reason for each, with the purpose of showing that scientific discoveries come from testable theories.
