There are many arguments over what happened to the dinosaurs. Scientist have one theory and religions have others. Scientist mainly believe that what killed the dinosaurs was a massive meteor. Religions, however, have theories that say everything from bloodshed and disease to Noah’s ark and a massive flood. In my opinion, the scientific theories seem more realistic and believable. This paper is going to discuss the theories and evidence that science provides and also the theories and evidence that religion provides. After I write about the scientific and religious points of view on dinosaurs I will then give my own opinion on which seems more believable and what i think happened to the dinosaurs.Scientists and paleontologists believe that a massive meteor strike killed off all dinosaurs. Scientists also believe that the meteor was only the final blow, they believe that all the creatures of that time were suffering from heat and air faults because of many volcanic eruptions. Scientists believe that years before the the meteor struck the earth volcanoes were erupting and killing off creatures and the ash from these volcanoes were also killing creatures. Scientists believe that the meteor that struck the Earth was just the final blow to kill off the dinosaurs. The only creatures that survived were small animals that could hide from the blast. Ones that could bury themselves within the ground and stay safe. These were the small mammals that dinosaurs hunted and ate. Scientists believe that the meteor was the final blasts that killed off the dinosaurs and the only creatures to survive were the ones that could hide themselves from the blast. Their proof is many fossils in layers of ash and also a giant crater on the

The possibility if a meteor strike as the cause of extinctions is discarded, something that most specialists agree on. There is no evidence of any meteor crater big enough or recent enough to be accountable for it; there are no “elements that are common extraterrestrially but less so on Earth, such as iridium, and no sign of a tsunami or other phenomena following the impact.” The extinctions where also very selective and occurred over a very long period of time. If a “one shot” catastrophe had been the cause it would have affected all species at the same time and in similar

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.
...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.

The Permian Triassic extinction was an event of cataclysmic disaster and almost the extinction of all species on planet earth. The Permian Triassic extinction is said to have occurred millions of years ago, geologist have estimated that its occurrences happened about 248 million to 286 million years ago. This rare occurrence of events proceeded the Triassic geologic periods and the Paleozoic and Mesozoic eras. This mass disaster was the largest dissipation of living life on planet earth; it is believed to be even superior to other crises such as the Ordovician and Devonian events and the conclusion of the cretaceous era that came upon the dinosaurs.
Dinosaurs are an extinct group of animals that thrived for 165 million years starting 230 million years ago in the Late Triassic period of the Mesozoic Era. Despite being extinct for the past 65 million years and not being able to study them in their true form, scientists have been able to estimate many different behaviors of dinosaurs. This paper will show that the close study and examination of different types of body and trace fossils, along with animal models, can be provided as evidence to estimate different types of behaviors in dinosaurs. The different types of behaviors examined below will fall into the categories of: mating; reproduction and nesting; social lives; locomotion; feeding; and fighting. To begin, a great deal of information gathered from fossils and compared to living animal models have been used to estimate mating behaviors.
This article was also particularly interesting to me because this is a recent find and there is little to no literature published concerning the idea that dinosaurs may have been cannibals. This is a new fossil find in which makes any and all research being administered equally as important. The time period of these fossils date back nearly 65 to 75 million years ago to the late –Cretaceous period when dinosaurs neared the end of their existence on earth. The fossils that have been discovered that tend to persuade researchers to believe dinosaurs were cannibals have been located in Northwest Madagascar’s bone beds. Rogers states, “ Fossilized soil samples from the same region are red and oxidized, hinting that the area was arid, with food in short supply. The animals may have traveled to the river to find sustenance and died there.
We use dinosaurs to represent the changes in nature that have occurred throughout time. Studies found that although the “oldest rock did not show evidence of life, the progression of plant and animal life that changed in recognizable intervals, from ancient life, age of reptiles to the age of mammals” (Dino Nature Metaphor, slide 6), measured the age of the earth. When we think of dinosaurs in relation to nature, we think of that very powerful force that controls the cycle of life. Nature was able to yield such magnificent ferocious creatures that walked the earth and then take them back when they served nature’s purpose. Dinosaurs fit perfectly in nature’s constant

“Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is written by Stephen Jay Gould, professor of geology and zoology at Harvard. This essay is one of more than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs – a confusing but an exciting problem that humanity tries to solve. By analyzing and describing each of the claims for the reptiles’ demise – sex, drugs, and disasters – Gould differentiates bad science from good science and explains what makes some theories silly speculations, while the other, a testable hypothesis.
Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.
