The Day The Mesozoic Dieded

The video that i watched was about how scientists didn't know what killed the dinos or when they were killed. So they researched and they explored all around the world about this and discovered that none of the dinosaur fossils were above the KT boundary. That gave them the idea that they should compare the fossils above and below the boundary. They also discovered that the meteor that caused it all was under the Yucatan Peninsula. They even figured out that the meteor hit the edge of one of the continents and the seafloor was pushed into little rocks.

The Day The Mesozoic Died

The video talk about the Mesozoic Era and how the dinosaurs died. The theory came when a scientist proposed that a astroid from space came to earth and kill all the dinosaurs. There is a boundary  called the K-T Boundary, witch separates the Mesozoic Era with Cenozoic Era. The astroid hit in Chicxulub, Mexico. Dinosaurs that were close to the astroid were broiled alive and killed instantly. Dinosaurs that were further away death came later for them.

The Day the Mesozoic Died

For a very long time they couldn't figure out why there was thin clay layer around the earth's crust. Many had seen this layer and they started to gather information and missing pieces to this problem. They thought that since in places there were different types of rocks mixed together that there had to be a bigger cause then just natural processes. They had realized they were coming closer to the spot were they thought was a meteor. They finally used new tech to get a narrow area to search. They had finally found the spot where it landed. They have later discovered that there isn't any of the same species below KT boundary and above KT boundary. There had been many discoveries since then.

The Day the Mesozoic Era Died

In the video they talked about how the Mesozoic Era came to an end, how they figured out how, and how life was post- asteroid. Geologists and paleontologists had spend years trying to figure out what the KT boundary was telling, and after looking at it all around the world, they came to the conclusion that an asteroid had hit the earth, that was the size of Mt. Everest. After the asteroid hit, the earth heated up and killed off all the dinosaurs and 60% of the plant life. Evidence of life below and above the KT boundary is extremely different, there hasn't been a dinosaur fossil found above the boundary anywhere in the earth. After the strike, life such as mammals and small reptiles that had big populations, somewhat survived. Then, the age of mammals began.

The Day the Mesozoic Died

A massive crater came down and nailed the surface of Earth in Southern Mexico. It caused an insane amount of impact that sent debris in every direction, as well as massive tsunamis that sent 100 M high waves that covered half the land. The amount of ash that was sent into the atmosphere completely blocked off the sun and prevented any organism that relied on photosynthesis to flourish. And for organisms that didn't rely on photosynthesis, they were practically boiled under the heat of the crater. Discovering the crater was a different process though.  It took lots of research and searching, but once scientists discovered the KT boundary things began to piece together. They discovered that the KT boundary contained a rare element that was only found in astroids, so obviously an astroid had to have been there. They also examined that the texture of the layers above the KT boundary was different than the texture of the layers beneath the KT boundary. Scientists found that dinosaurs were only found beneath the KT boundary and above the KT boundary scientists were completely whipped out. They went and did more research down in Texas and discovered that mud from the bottom of the ocean was on land so it must've been underwater at one point in time. They continued to follow the information they gathered and they finally discovered a massive crater in the Ukantan Peninsula in Mexico that contained the same elements that was found in the debris that was found all over earth and in the KT boundary. Another thing that pieced it together was that half of the crater was in the water and half of it was on land so it would have sent waves all over Earth causing large tsunami's and dragging ocean mud onto present surfaces that ocean mud wouldn't be expected to be found.

The Day the Mesozoic Died

Once ago scientists believed that mesozoic era ended by very slow change overtime. But then a man thought otherwise. He thought they they all died in an instant by a giant meteor. Scientists wouldn't believe this catastrophic event. So he went out to prove them wrong. He eventually found a giant crater in Mexico. There him and his scientists found fossils of land and sea animals. You could just find them lying around all around the ground. He also found that rocks that could only be that way unless a catastrophic event happened. He proved those scientists wrong and today we believed that a meteor killed all the dinosaurs.

The Day The Mesozoic Died

The day the Mesozoic died, millions of years ago. There is a lot of proof of when they died, a lot of it has to do with the layers of the earth. All of the fossils are different and have different animals and fossils in them. When the meteor hit the Earth, it caused major amounts of heat to be put on all of the animals near it. All of the debris in the air blocked out the sun to the plants and animals. Once some of the animals started dying, it killed off others. And without the sun plants couldn't produce photosynthesis and they all died off.
