Dinosaur Fossil Discoveries in Antarctica
The chance of two different research groups finding two different fossils that are in fact two different kinds of species within the course of a week is close to impossible. However, this rare and lucky occurrence in the paleontology world has occured. Two research teams have retrieved fossils of two different dinosaurs in Antarctica that might possibly be unknown species.
Judd Case and James Martin discovered bones, specifically those of the lower legs and feet, as well as the animal’s upper jaw and teeth. These fossils are said to be related to the carnivorous theropods, such as tyrannosaurs and velociraptors. Theropods have been related with birds and this new fossil’s feet as well as teeth relate it to the extinct carnivores. Also, due to the size and shape of the foot and leg bones, the animal is said to be a running dinosaur about six to eight feet tall.
Thousands of miles away from this excavation sight and during the same week, William Hammer and his research team were in the mountains of Antarctica, about thirteen thousand feet, specifically near the Beardmore Glacier. The pelvis to a plant-eating dinosaur was found buried in solid rock. This pelvis is said to belong to a family of the sauropod, such as the brachiosaurus and diplodocus. “... Hammer and his fellow researchers believe the pelvis- one meter (three feet) across- isfrom a primitive sauropod that represents one of the earlier forms of emerging dinosaur lineage that eventually produced animals more than thirty meters (100 feet) long” (www.nsf.gov 2004). This animal is estimated to be up to seven feet tall and thirty feet long.
These findings are important to paleontology as scientists work to discover more about the Earth’s past. These fossils give more insight into the Earth’s environment million’s of years ago. The fact that these fossils may be new species’ that paleontologists were not even aware of shows how little we may know about the history of the world and what other life walked on the Earth.
Ceratopsians and Pachycephalosaurs are closely related in their characteristics. Ceratopsians processed a saddle-shaped boney frill that extended from the skull to the neck and typically had horns over the nose and eyes. The most popular was the triceratops, which could reach over 26 feet and weigh in excess of twelve metric tons. Their frills served as two major functions. It protected the vulnerable neck from being harmed. The second major function that the frill provided was due to the fact that the frill contained a network of blood vessels on its underside, which were used as a means to get rid of excess heat. The Pachycephalosaurs were considered to be bipedal. They were also found to have thick skulls, flattened bodies, and tail that were covered in an array of body rods. Pachycephalosaurs were thought to have been more than fifteen feet long and processed a skull that was surrounded by a rounded dome of solid bone. It was thought that they used their heads in combat or mating contests, but that was disproved fairly recently, which I will discuss later in the paper. Both Ceratopsians and Pachycephalosaurs were “bird-hipped” and both of these suborders contained a backwards pubic bone. Both were Marginocephilia, or “fringed heads”, which is one of three clads under the Orinthiscia order. They were also herbivore dinosaurs that inherited their fringe at the back of the skull from earlier ancestors.(2) Their classi...
There was a chief new discovery of fossil bones and teeth belonging to the earliest human ancestors ever discovered. The fossil bones predate the oldest formerly discovered human ancestor by more than a million years. The discovery was of fossil remains of a hominid that lived in present day Ethiopia between 5.2 and 9.8 million years ago. (Hominids include all species following the split as of the chimpanzees on the “human” side of the evolutionary tree.)
The question of what caused the extinction of megafauna during the Late Pleistocene period is one that archaeologists have struggled to answer for decades, but why should it matter? Discovering with certainty the cause of megafaunal extinction would simultaneously prove or disprove any of the proposed implications of each existing theory regarding this massive extinction.
Majungatholus atopus roamed the plains of northwestern Madagascar about 70 million years ago during the Late Cretaceous (Perkins, 2003; Rogers et al, 2003). The discovery of 21 tooth-marked elements originating from two Majungatholus atopus individuals suggests evidence that the dinosaur supplemented its diet by feeding on its own dead or hunting them (Rogers et al, 2003). It cannot be confirmed whether they were purely scavengers, hunters, or both. Scientists are certain that the marks are not the doing of any other predator because the teeth marks are not consistent with any other known species that lived in the area. Only one other theropod that inhabited the area during the time Majungatholus atopus did, Masiakasaurus knopfleri, had teeth and bite marks too small to have caused these markings. Two large crocodile species also shared the same ecosystem but their teeth were “too blunt and too irregularly spaced to have produced the narrow grooves found on the Majungatholus bones”(Perkins, 2003). The tooth marks on at least nine Majungatholus elements attest to intertooth spacing in the perpetrators jaw and denticle drag patterns consistent enough to make a compelling case for Majungatholus feeding on other Majungatholus (Rogers et al, 2003).
The new discoveries raise many questions about the origin of modern man. Tim D. White, the project’s director claims that the Herto fossils prove that...

Some research has reported finding insects fossilized in amber, containing species such as a termite (30 million years ago), and a weevil from approximately 130 million years ago. These are extraordinary findings, but of course disputed. ...
A major strength that Netflix has is their ability to push for such innovation. They have reached new lengths since their start in 1997. From in-mail DVDs, to streaming media on smartphones and tablets, it’s unbelievable to witness this in the making. I think the world is a little shocked on the technological advances of Netflix. What they have done so far is spectacular and it is all because of innovation. New ideas and new strategies developed over the last fifteen years has lead Netflix to where they currently stand today. They currently have a subscriber base of over 700, 000, offering thousands of titles on many different devices. This was made possible because of their ability to innovate and strive for new technological advances. I consider Netflix a very brilliant company. Their strengths are very clear, but this isn’t to say that they have no weaknesses. Netflix has far more competitors now, than they had 15 years ago. I would say that their biggest weakness is not offering enough newer content. Some of their competitors such as Hulu, offer a ridiculous amount of new content. Netflix seems to have a large amount of titles, but majority of these titles are older titles. They need to offer newer titles more often than less. With the company advancing and technology on the rise, the younger population aren’t into the older titles. The younger population now take up a good chunk of the customer base. Netflix must
Until recently, scientists believed the chances of finding a fossilized dinosaur heart were extremely slim. The heart belonged to a 66 million year old dinosaur found in Harding County in Northwestern South Dakota. The dinosaur, found in 1993, weighed over 650 pounds and was 13 feet long. The dinosaur was in fairly good condition with the exception of the left side of the skeleton. The small, plant-eating Thescelosaurus, nicknamed ‘Willo’ has been acquired by the North Carolina Museum of Natural Sciences. Thescelosaurus was an ornithischian, or "bird-hipped," dinosaur that lived in the latter stage of the Cretaceous period. This was approximately 1 million years before the end of the dinosaur era. Native to North America, its range extended from the northern United States up into Canada. Since using the 3-D software to reveal Willo's heart, scientists have also used it to create 3-D images of the fossil's skull, and of remains from other dinosaurs in the museum's collection.

CEO compensation has been a heated debate for many years recently, and it can be argued that they are either overpaid or that there payment is justified by the amount of work they do and their performance. To answer the question about whether CEO compensation is justified it must be looked at by the utilitarian viewpoint where the good of many outweighs the good of one. It is true that many CEO’s are paid an exorbitant amount of money; however, their payment is justified by the amount of money that they bring back to the company and the shareholders. There are many factors that impact the pay that the CEO receives according to Shah et.al CEO compensation relies on more than just the performance of the CEO, there are a number of factors that play a rule in the compensation of the CEO including the fellow people who help govern the corporation (Board of Directors, Audit Committee), the size of the company, and the performance that the CEO accomplishes (2009). In this paper the focus will be on the performace aspect of the CEO.
The Burgess Shale Fauna is a fauna that was constructed based on a group of fossils that were initially found, in the Burgess Shale area in the Canadian Rockies (Gould, 1989). They are a very important group of fossils as “modern multicellular animals make their first unprotected appearance in the fossil record some 570 million years ago” through this group (Gould, 1989, pp. 24). Moreover the Burgess Shales are known to have preserved the soft parts of animals enabling us to get a better understanding of life at the time.
For instance, the whale, the biggest mammal that lives in the water, was found to have had legs and used to dwell on land millions of years ago. While in Pakistan, Phil Gingrich, a geologist and paleontologist, came across a fossil that resembled that of a wolf but had a “bump” on the back of the skull which was found to part of an inner ear,
Over the past century, the Burgess Shale has revealed important information about the development of earth’s history. The excavation of the Burgess Shale formation provided evidence for what was once just a theory in evolution. The taphonomic findings of the Burgess Shale have played a significant role in understanding the large diversity that resulted from the Cambrian explosion, advancing the study of evolutionary assemblages for Paleontologists worldwide.
The importance of teams is becoming more and more apparent in today's dynamic business world. Increasingly managers are searching for a means to improve production and keep their organization competitive in the global market. A lot of these managers have turned to the team as a means for achieving this improvement. Quality circles were originally looked at to fulfill this role, however they are being phased out in favor of self-managed work teams. These teams are increasingly being used to solve many of today's organizations production problems and inefficiencies, and in the process are both badly failing and greatly succeeding. So the discussion of teams is a very important one to address. Managers should be aware of the concept of teams and learn about as a means to further their organization and for when the time comes to implement a team they are prepared with the knowledge needed to build and use a team properly.
