What Really Happened to the Dinosaurs? - During the course of history, two theories have evolved that explain what happened to the dinosaurs.  These two theories have been debated back and forth between evolutionists and religious followers.  Evolutionists believe that dinosaurs became the most powerful beings on Earth around 235 million years ago.  They believe that no humans existed at the time.  Evolutionist views also say that all the dinosaurs were killed by a cataclysmic event.  On the other hand, the Bible says that God created the dinosaurs on the same day that he created Adam and Eve (Ham, 2007)....   [tags: Evolutionists, Biblical Views, Dinosaurs]

The Significance of Dinosaur Art - The Significance of Dinosaur Art Dinosaurs are creatures that seem to fascinate humans, since all we have left are their fossils. Although, through art, their bodies can be put back together and we have a better sense of what they looked like. The problem with art is that pictures can sometimes be disproportionate, unrealistic, or even made up. Young children who learn about dinosaurs may think that they are actually different colors and can talk for example. This is why it is important to make dinosaur art as realistic as possible and more informative....   [tags: Exploratory Essays Research Papers]

Investigation of the Polar Dinosaur - Investigation of the Polar Dinosaur Today we know through the evidence of fossils that dinosaur and other large reptiles once lived on every continent on earth. If you were a paleontologist in charge of finding fossils where would you look first. In the search for evidence the icy continent of Antarctica would be perhaps the last continent you would think to search. However, during the last twenty years a remarkable number of prehistoric fossils have been found in regions close to the South Pole....   [tags: Exploratory Essays Research Papers]

The Cause of the Dinosaur Extinction - The Cause of the Dinosaur Extinction The biggest mystery surrounding the dinosaur is how did they die. For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.). Some have ventured that early mammal inhabitation slowly “pushed” the dinosaurs to extinction....   [tags: Papers] 835 words

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]

Amniotes (a group which in the Triassic spilt into reptiles and synapsids and which include dinosaurs), have large nasal openings, but since the nostril is made up of flesh and cartilidge, it is almost always not preserved in the fossil record (Lauren and Gauthier 1996)....   [tags: Anthropology Essays Paleontology Papers]

But what children see on television: the scaly green skin of the brontosaurs or the brown hair of a mastodon may not hold much fact.

Examining the Cretaceous: Paleogene Extinction Event - ... Some paleontologists believe that the global ecosystem had already been on decline before the final blow, an asteroid, destroyed much of life on earth. Continental drift and seafloor spreading may have shifted oceanic circular patterns, causing dramatic changes in sea level and the earth’s climate. Also, the end of the Cretaceous period, immediately preceding the K-Pg, saw many volcanic eruptions; the dust and gases released are thought to have caused great environmental changes. However, the tipping point occurred when the Chicxulub asteroid slammed into Earth releasing energy “a billion times more than the atom bombs that destroyed Hiroshima and Nagasaki,” (Choi, 2013)....   [tags: dinosaur, ecosystem, disasters, astoroid] 547 words

When this process does not happen slowly, the original hard parts often lose all trace of their original structure, leaving the original shape, but no detail (Virtual). Permineralization is the most common form of fossilization of dinosaur skeletons. It occurs when the ground water carrying dissolved minerals permeates the pores and cavities in bone, wood, or shell (K). The minerals then produce stony fossils that still contain most of their original solid material.

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).
