Discoveries of the (Dinosaur) Incisivosaurus Gauthier, and (Hominid) Sahelanthropus Tchadensis - Discoveries of the (Dinosaur) Incisivosaurus Gauthier, and (Hominid) Sahelanthropus Tchadensis In the year 2002 a bizarre looking theropod dinosaur fossil was found in China (Xu). It challenges the way researchers have been thinking of theropods and other dinosaurs for a long time. In the Sahara desert, the oldest hominid skull in the world was found that same year. These are just two of many discoveries that have challenged the way we perceive the ancient world. Incisivosaurus Gauthier was what is believed to be a primitive Oviraptorosaurian that was recently discovered in China....   [tags: Anthropology Essays Paleontology Papers]

Theropod Discovery Challenges the Dinosaur-to-Bird Theory - Theropod Discovery Challenges the Dinosaur-to-Bird Theory For years, it has been believed that Dinosaurs are ancestors of modern day birds. By simply looking at pictures of dinosaurs, one can find many physical similarities between these reptiles and modern day birds. Often the legs and the chest cavities are very similar in shape. Some dinosaurs have limbs that look like they could evolve into modern day wings, some dinosaurs even had feathers (6). A recent discovery in Italy of an extremely well preserved Scipionyx samniticus challenges this idea....   [tags: Anthropology Essays Paleontology Papers]

Microraptor Gui: The Dinosaur with Four Wings - Microraptor Gui: The Dinosaur with Four Wings Knowing that pterodactyls belong to a separate group of reptiles than dinosaurs, the thought of a dinosaur with wings may seem somewhat strange. But a fairly recent archeological find adds an extra detail to make this idea truly bizarre: a dinosaur with four wings. Microraptor gui, discovered by Xing Xu and colleagues, is believed to be a kind of missing link between strictly ground-dwelling dinosaurs and birds, namely Archaeopteryx, the earliest known creature to be considered a bird....   [tags: Anthropology Essays Paleontology Papers] 1527 words

Characteristics and Behaviors of Pterosaurs - Characteristics and Behaviors of Pterosaurs Overview Pterosaurs were not dinosaurs but were closely related, and existed for 150 million years beginning in the late Triassic period through the Jurassic and Cretaceous periods until eventually becoming extinct along with the rest of the earth’s population at what is now known as the KT boundary event. The KT boundary event was the mass extinction that occurred at some point in time between the Cretaceous (K) and the Tertiary (T). This is famous because it marks the end of the 160 million years of dinosaur life....   [tags: Anthropology Essays Paleontology Papers]

A New Species of Whale - Questions Surrounding a New Species of Whale During the month of September in 1998 an amazing and unique discovery was found by a group of scientists when they went out to the Sea of Japan. There, they collected the carcass of a medium sized baleen whale. This was the ninth specimen needed to complete the research on discovering this new species. This species of the baleen whale did resemble the fin whale, another species of the baleen whale. However, this carcass was much smaller in size. After comparing DNA data of the external morphology, osteology, and mitochondrial, scientists were able to classify all they found into a new and different species....   [tags: Anthropology Essays Paleontology Papers]

Savanna Theory Versus Aquatic Ape Theory of Human Evolution - Savanna Theory Versus Aquatic Ape Theory of Human Evolution The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove....   [tags: Anthropology Essays Paleontology Papers]

Dinosaur Fossils in Antarctica - Dinosaur Fossils in Antarctica Millions and millions of years ago the continents lay together as one super-continent known as Pangea. As time went on and the plates underneath the Earth began to separate, the continents land moved towards the poles where glaciation occurred. Glaciation is the process in which glaciers were formed during the ice age. Glaciation causes a drop in temperature which in turn causes water to freeze and form many layers of ice (http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro.html, 1)....   [tags: Anthropology Essays Paleontology Papers]

At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species....   [tags: Anthropology Essays Paleontology Papers]

This statement comes from a person who knows little about science, and less about the specific scientific techniques used in archeological excavation and analysis.

Neanderthal Extinction - Neanderthal Extinction   Neanderthals and modern humans coexisted for well over 100,000 years.  Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.  Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.”  What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct....   [tags: Anthropology Essays Paleontology Papers]

Recreating Prehistoric Life: Jurassic Park - Recreating prehistoric life is at the fore-front of interest in the scientific community. Large strides have been made in uncovering the genome sequences of Neanderthal. Within a few years, scientists hope to unravel our relatives’ entire genetic code. With Neanderthal cloning staring us in the face, a more seductive idea has emerged with immense support from the media. The idea of cloning dinosaurs and other prehistoric life became popularized by the 1992 film Jurassic Park (based on Michael Crichton’s 1990 novel)....   [tags: Film Analysis]

Stephen Gould: The Savior of the Scientific Essay - Stephen Jay Gould was born on September 10, 1941, in New York City. As a young boy at the age of five, Stephen went to the Museum of Natural History in New York City where he saw the Tyrannosaurus Rex along with other large dinosaur skeletons. He decided that he wanted to study the fossils and evolution; he began to read up on as much information as he possibly could. As Stephen grew older, he discovered that there was a specific field of study that would fit in with his interests. This field of study is called paleontology....   [tags: notorious palenteologists]

Issues of Tempo and Mode in Evolution - There are many ways to explain how Earth and everything else came to be. Such as, Uniformitarianism, Catastrophism, Gradualism, and Punctuated Equilibrium. Generally, Uniformitarianism and Catastrophism are grouped together while Punctuated Equilibrium and Gradualism are grouped together separately from Uniformitarianism and Catastrophism. Gradualism and Punctuated Equilibrium are usually looked at through a biblical stand point rather than how Uniformitarianism and Catastrophism are looked at from the opposite view....   [tags: Evolution]

Demise of the Permian- Triassic Period - Demise of the Permian- Triassic Period It is well known that there was a mass extinction killing the dinosaurs. However 185 million years before their demise, almost all life on earth was destroyed.1[1] There has long been theories that meteorites are the cause the of the mass extinctions and professor Asish Basu believes he may have found clues that point to space as the cause of the extinction in the Permian- Triassic period.2[2] The Triassic period is during a time when the earth was divided in a giant land mass: pangea, and water....   [tags: Exploratory Essays Research Papers]

Jungian Theories - Jungian Theories History: Carl Jung was a Swedish psychiatrist and a psychologist. And during his 86 years of life, from1875 to 1961 developed the analytical psychology. He based his theories on the works of his close friend and mentor Sigmund Freud: the psychoanalytical theories. Early on in his career Jung followed Freud and supported his theories, but as Jung found aspects of Freud's theories that he found disagreements with, Jung parted and formulated his own (Anthony). In turn, his theories would "go beyond psychology and affect theology, philosophy, and anthropology", according to George H....   [tags: Papers] 1303 words

At first, Johanson thought the knee belong to a monkey or baboon, but it didn’t seem like it belonged to such an animal. He sent the bones to Owen Lovejoy, an anatomist and part-time forensic expert. Lovejoy examined the bone fragments and concluded that they appeared human. The joint could “lock”, suggesting the animal could walk upright. This was an important discovery showing an ancient bipedal creature. If the bones’ age was consistent with Johanson’s hypothesized “missing link”, it would serve as supporting evidence to Johanson’s theory....   [tags: evolution, bones, scientists] 975 words

Charles Darwing and The Theory of Evolution - ... In October 1825 Darwin went to Edinburgh University where his grandfather studied to study medicine with a view to becoming a physician. He soon realized that he does not like the study of medicine and could not bear the sight of blood or suffering. So here changed schools and went to Cambridge to become a clergyman. Then he soon noticed he would like to be a naturalist. His theory of evolution by natural selection is what he is best known for today and is now the unifying theory of life sciences explained where all of the mindbogglingly heterogeneous kinds of living things came from and how they became exquisitely adapted to their particular environments....   [tags: biology, galapagos, natural selection]

A Comparison of Historically Significant Fossil-Lagerstätten - A Comparison of Historically Significant Fossil-Lagerstätten Lagerstätten are fossil-bearing assemblages that, in most cases, contain exceptionally preserved specimens. These assemblages are useful in recreating paleoenvironments and are considered to be windows to the past. Two types of Lagerstätten are recognized: concentration and conservation. Concentration Lagerstätten are useful in determining the composition and reconstruction of food webs. These sites are determined to be true concentration Lagerstätten if they demonstrate a mechanism of concentration rather than merely presence of diversity (Nudds & Selden 2008)....   [tags: specimens, scottland]
