The Asteroid Theory: The Extinction Of Dinosaurs

Mysteries are so fascinating because mysteries are like taking unknown information, discovering it, and making it known. Discovering why dinosaurs went extinct is looking into the discovery of their extinction and why they are extinct. Dinosaurs were the largest reptiles known to man, and around 65 million years ago, dinosaurs became extinct. Two-hundred and thirty million years ago the first dinosaur-like creature roamed the earth. These creatures were the top of the food chain, and it is crazy to think that the most dominant of all species became extinct. But there had to be either a theory such as ‘The Asteroid theory’, ‘The Ice Age theory’, or the ‘Volcano Theory’ to explain such drastic measures for the entire population to die out. This is where the mystery takes place and begins.

There are many scenarios of the history of the extinction of dinosaurs. The mystery

behind it all revolves around the many theories made up to wipe out the entire species. “Until recently, people simply knew that dinosaurs were extinct- they were found throughout the Mesozoic era, so we knew that they were extinct some 64 to 66 million years ago, but that was all. Many wild ideas about how dinosaurs rendered extinct were presented over the years.”(The Great Mystery, dinobuzz-ucmp.berkeley.edu) Around 46 theories have been been made since 1963. The only probable cause most known is the Ice Age Theory, The Volcanic Theory, and The Asteroid Theory.

The theories most known for the cause through had to do with the supposed killing leading to 70% of the population dying from one of these theories.

That means that 30% still had a chance at life and being reborn in mysterious ways. Have you ever thought that when evolution occurred there was still a chance of “dinosaurs” existence? The word dinosaur comes from the greek language and means ‘terrible lizard’ ” (sciencekids.co.nz/sciencefacts/dinos). Meaning dinosaurs are an occurring species we see most likely in our everyday life in a more evolved species that is much smaller, such as other reptiles like lizards and alligators. The asteroid impact theory though is most known to kill the huge species known to man. “This 150-kilometer-wide crater lies just off the yucatan peninsula. Scientists calculate that it was blasted into earth by a 10-kilometer wide asteroid or comet traveling 30 kilometers per second -150 times faster than a jet airliner”)pbs.org/wgbh/evolution (dino extinction) therefore proving our reasoning to the death and extinction to the mass large population of

dinosaurs.

We believe that our topic ‘The extinction of dinosaurs’ was learning more about why the dinosaurs went extinct, but the more we learned, the more we believed dinosaurs weren't extinct. The asteroid theory is the most proven theory but “only 70% of life on earth died”(national geographic.com) . During that time if you think about it “only about 5% of the ocean has been discovered”(ocean service.noaa.gov) and there were water dinosaurs. The impact may have affected the water and its cleanliness to be able to live in it, but there is still a chance, we believe, because of the lack of information on the species in the ocean that our mystery may still be a mystery. Did Dinosaurs really go extinct? And was one of the many theories really enough to kill 100% of the dinosaur species? These great lizards and largest reptiles known to evolved into a smaller species? We believe dinosaurs are not completely extinct and may have just simply evolved.
