The Mesozoic Era free essay sample

In this report I will be explaining a few facts about the Mesozoic era coming from the documentary â€Å"The day the Mesozoic Died†. This small film expresses how in many ways these creatures once inhabited our planet and disappeared completely in almost a blink of an eye. The Mesozoic Era could also be described simply as what most of our population knows as the Dinosaur Era. These creatures once dominated our lands with tremendous sizes, shapes and species and although humans were never able to see one in person, there are many ways in which our scientists and geologists have found to identify what they looked like and how they behaved. Thanks to their effort, we can now understand the tremendous creatures who lived before us and assume theories as well as research to find out why and how they were completely wiped out our planet one day. Body The disappearance of dinosaurs is considered a mystery for many reasons.

There are many theories as to what could’ve happened. On the other hand, the most common one could be derived from the information found by geologists all over the world discovering unusual patterns on the rocks and mountains of certain places. Within the discoveries found all around the world scientists have found a few rare chemical elements in the process of the search. Some of the chemical elements included were the iridium, cosmic space dust, the isotope plutonium 244 and sulfur as well. Currently, the main suspect behind this catastrophe is a cosmic impact from an asteroid or comet, an idea first proposed by physicist Luis Alvarez and his son geologist Walter Alvarez. Scientists later found that signs of this collision seemed evident near the town of Chicxulub in Mexico in the form of a gargantuan crater more than 110 miles (180 kilometers) wide. The explosion, likely caused by an object about 6 miles (10 km) across, would have released as much energy as 100 trillion tons of TNT, more than a billion times more than the atom bombs that destroyed Hiroshima and Nagasaki. However, further work suggested the Chicxulub impact occurred either 300,000 years before or 180,000 years after the end-Cretaceous mass extinction. The scientists involved in this investigation were Sean B. Carroll, Alan Hidebrand, Kirk Johnson, Mark Nielsen, and Jan Smit. The places visited in the film to prove the investigation were Gubbio, Italy, Zumaia, Spain, Brazos river, Texas, Dakotas and Montana. They found many pieces of evidence for example patterns, rocks, leaves and elements. But the most important piece of evidence was the crater in the gulf of Mexico called the Chicxulub which led out to match every hypothesis the geologists made. The chemical elements they discovered were important for the fact they are not Earth made elements and come from outer space. The investigation took place in 2012. My personal opinion for this film would be that I think its really great. It was outstanding information and a very interesting topic as it is one of my favorites. Conclusion In conclusion, this specific topic is one of huge interest expressed all around the world. The events that happened on that very day the dinosaurs disappeared are a huge contribution to our history. It was a very tragic event, but yet it could be expressed as the most important one. Why is it important? Without the end of the Mesozoic era, there would have been no beginning to our era. Without the dinosaur wipeout, there would be no us. We cant completely say that all Mesozoic died on that day. There are still creatures among us who participated in that era. It is believed that some reptiles such as Alligators and lizards are related to dinosaurs, as well as a few other creatures. Now a days scientists and geologists still live with the mystery and are still trying to find more pieces of evidence or fossils that might remain. It is important to know our past, therefor we must be thankful of what such a tragic event gave birth to up to this day, us mammals and the centuries we have lived and move on to keep living.
