Dinosaurs are a group of reptiles that became extinct 65 million years ago. Over the course of the 4 million years we have been living, scientists have observed our world. Scientists have taken scientific facts combined with the bodies of many Dinosaurs to help come up with theories about extinction. As scientists found more dinosaurs they wondered how dinosaurs became extinct. Scientists realized that our planet had been inhabited by another mammal before humans. Numerous ideas have been discussed about why dinosaurs disappeared. Three theories explaining extinction are most common among scientists.
One theory about the extinction of dinosaurs is the Volcano Theory. The Volcano Theory involves the idea that erupting volcanoes are the reason that dinosaurs became extinct. Scientists examined the bones of dinosaurs and observed how well the bones were preserved. There was increased

“Unfortunately, we still have the problem of pesky Frogs,Crocodiles, Turtles, Marine species, and mammals survived.” This theory seems a little far fetched, because think about it. Why would mammal that are 2 times smaller eat a animal that is twice their size? They would not! So in basically the Dinosaurs would try and eat the mammal trying to eat other Dinosaurs. That is why this theory seems a little far fetched.
Now 65 million years later we come with new theories everyday. As scientists come closer to see what the exact reason that Dinosaurs died. But, of the plausible theories on how Dinosaurs went extinct many have tried to decipher the facts of each theory to find which possibly happened. Scientists examined the bones to see how they were preserved to see what was possible. Since scientist can’t agree on what happened to the Dinosaurs scientist argue over the theories. In conclusion Volcanoes, Meteorite, Mammals all might have happened and made the dinosaurs go
Ken Ham proudly supports this theory by many displays of dinosaurs in the museum to remind Christians of this theory in Genesis. Bill Nye makes a a spectacle out of this theory, Again, Bill Nye discusses about dinosaur fossils dated back millions of years ago and to go visit secular
The reading claims that, Edmontosaurus migrated every Winter and Provide some Reasons to Support the hypothesis. HOWEVER, the Lecture disagreed with the statement and LOGICALLY refutes each of the Reasons. Firstly, the Lecturer Claims That, Edmontosaurus did not migrate to Find Food. She said that, summers were warmer than today, and the sun shines 24 hours a day.
The theory of the asteroid being the reason for the extinction of the dinosaurs and with the help of some colleagues, it was able to confirm the extinction of the extinction
Then there are the two worst kinds of dinosaur that the characters have to deal with. The velociraptors and the tyrannosaurus. The raptors are lean, mean, killing machines that have an extraordinary level of intelligence by the standards of dinosaurs. The tyrannosaurus is simply a gigantic monster that will kill just about anything on sight. As I mentioned before, the book plainly becomes a survival book.
T Natrix tells Wart a old story about the dinosaurs. There were two types of dinosaurs, a bloodthirsty carnivorous dinosaur and a peaceful herbivore. The carnivorous dinosaurs eventually went extinct after losing a war with the herbivores, and eating themselves because of starvation and their bloodthirsty needs. Eventually, there was one herbivore left. Man came across this dinosaur, and killed it, because he recognized all dinosaurs as killers.
Archaic period sites across Mesoamerica resemble the same building methods and technology used by other groups spread throughout the Southwestern and Southeastern regions of North America. Artist 's depiction of an Archaic period village.[224] Paleo and Archaic era groups carried influenced technologies from these groups with them as they migrated into the Mesoamerican region. These were the hunter-gather groups that were beginning to settle and merge into archaic settlements. These groups learned and developed near similar technological concepts and ideas within their own cultural practices.
He was scared, but if he was less selfish and actually thought about what he was doing, he would have stopped talking. Because he continued to speak, he alerted the dinosaur to their being in the area. This led to big consequences for the other four men who were on this hunting trip that the dinosaur spotted them because it advanced on the men, not allowing them to make the first move. The first move is very significant because the attacker can catch them by surprise and it proves that to the opponent that they are the alpha dog. The dinosaur was the one who attacked, which made it hard for the hunters.
The main reason to this is because the fossils were not encased neither were they close to any foreign datable material. Making this even more difficult no singular organisms were, found close to the fossils that could be, used for dating. Inability to date the fossils from surrounding objects leaves only two options both of which raise the issue of accuracy. The radiocarbon dating method which could be done on the fossils is only accurate in fossils which are 50,000 years or younger. Consequently, this dating method also raises the issue of age limit as it posses the risk of providing an upper age
The Earth's climate went through several major changes throughout the Tertiary period that led to the flourishing of primate species and the extinction of other primate species. The plesiadaptiforms, which are not considered real primates because of the lack of key primate features, went extinct at the end of the Paleocene epoch. At the beginning of the Eocene epoch came the euprimates, considered the first real primates, whose features made them well-adapted to arboreal life. Euprimates had convergent eye orbits, opposable digits, nails, and larger brains than plesiadaptiforms. This coincides with a period of global warming which made for a more tropical and forested habitat.
Jurassic Park is a classic science fiction film about the problems one may run into when cloning dinosaurs and creating a Jurassic environment. However, the meaning behind the film may not be so obvious. A viewing of the film makes us question the future for paleontology, cloning technology, and human relationships. Why would the park open with dangers like velociraptors, tyrannosaurus rexes, and other carnivorous, strong, fast, and practically unstoppable dinosaurs present? How do the characters in the film treat death?
Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction.
Once they are in the past and see the Tyrannosaurus Ray Bradbury uses imagery to explain what the dinosaur looks like. The Tyrannosaurus was described as, “...thirty feet above half the trees, a great evil of god, folding its delicate watchmaker’s
When strange creatures continue to be found on a private Costa Rican island, it draws the eyes and ears of paleontologist Richard Levine and his acquaintance, Ian Malcolm. These two brilliant individuals combine forces and investigate what they refer to as “the lost world.” At first, Malcolm is in denial and does not want to believe in the fact of dinosaurs still being alive due to his last experience and almost dying. This forces Levine to travel to Costa Rica for a weekend to observe the mysterious corpses. With fear of the government suddenly finding out about the island, Levine sets out for the island himself with his young guide Diego.
Scientist have discovered the bones of what may be the largest meat-eating dinosaur ever to walk on earth. The discovery was made by a team of researchers from Argentina and North America in Pantagonia, a desert on the eastern slopes of the Andes in South America. Besides the interesting fact that the dinosaur was huge and horrifying, the dinosaurs may have lived and hunted in packs. Before the discovery, the Tyrannosaurus Rex was believed to live in North America, to hunt and to live alone.
Obviously, the real analogy would be the butterfly preceding the cocoon, but animals in the Lepidoptera order coexisted with dinosaurs. These were not just butterflies but also moths, and they lived during the Triassic period, which is a big deal. Fossil-based data collected in this new study suggests they lived over 200 miion years ago but possibly as much as 250 million years ago, and this prehistoric butterfly was reportedly much more like a moth in the first place than any butterflies currently
