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.

The day the mesozoic died

I would say that this video helped me a lot. The k-t boundary was really the turning point towards dinosaurs. When that meteor hit, it was the end no matter what. The tsunami though was really interesting. I didn't know that that was a way for the the rocks to move all over the world. The part about how Wyoming had that big tsunami hit it and make all the rocks split up the fossils was confusing because I thought that all the dinosaurs died fast due to the meteor exploding and shooting lots of things in the air. The leafs remains in the rocks  was extradorniary because I never knew even the color would stay the same even through that many years.

The day the mesozoic died in when all the dinosaurs died. A huge astroid hit earth at a very fast speed and collided with earth and made a huge explosion. The ash and smoke stayed in the air for a very long time and photosynthesis  died out and killed all the producers and then soon all the consumers died because they couldn't eat. You can find fossils all over the world form the dinosaurs and when you look at the mountains on earth you can tell by certain signs that somethings happened in earths history bc it looks different then before.

The Day the Mesozoic Died

In the video I watch, they talked about many things. One thing they talked about was that if an asteroid that was 10 kilometers deep landed on a sea or an island, it would displace incredible amounts of rock and water, that can cause tsunamis. The scientists took rock examples to use in the lab that showed all the signs of a high energy impact. This made everyone believe that there was a big crater buried on the peninsula. Later they named the crater the Chicxulub crater. 

When you crack open rocks you can see the leaves on plants and can tell what insects ate them. Fossils fill the whole place, which describes uniformitarianism which says that things in the past also happen today, which fossils do. Scientists found a boundary they named the KT boundary, which can tell the age of fossils. This boundary helped determine where many things lived because they can tell where in comparison they were from the boundary.

Smoke from fires later filled the air, as long as sulfur that exploded in the air, the Mesozoic era, the life of dinosaurs was over.  This wrecked over 60 percent of plant life. The asteroids were very bad within life back then. Many disasters occurred and many things died down.

           The Mesozoic Era was a time of many different creatures, especially dinosaurs, but they weren't there the whole time. Much of the land was underwater, which is marked off by a layer called the K-T boundary. When a meteor around ten kilometers wide hit the Earth, though, it displaced a lot of the water and land. All of the displacement as well as the debris coming off of the meteor buried most of the animals, not leaving much. A few of the smaller animals luckily survived the day the Mesozoic died, which left a promising future millions of years later for us.

The day the mesozoic died

In the video it started out with a discovery of the tk boundary. They explained how this told us about the eras and periods before us. They also showed us how to find a boundary and a difference between a boundary. They also showed us a discovery of a boundary.

After they taught us about the tk boundary. They then showed us how the mesozoic died and how they went extinct. They were all killed by an astroid that was aiming towards the earth. It landed by Mexico which killed all of the dinosaurs. That is how they were all killed.

The Day the Mesozoic Died

The Chiczulb crater has finally been found next to a town next to the gulf of Mexico. Researchers went out and looked to see which animals went extinct and ofter questions. Curt found the KT boundary in north dakota, and when he found that he could answer many more questions.  They are finding carbo films. fossils. and what insects eat what things. They are finding fossils almost anywhere, big, small, long, short. They have found out that 22 type of of dinosaurs lived in hell creek.

At the beginning of the video they were trying to find the cater that killed off the dinosaurs. it was 100 kilometer wide, and the sky was covered in smoke and the sky was not visible. Dinosaurs next to the crater died because of ashes and sparks just boring them to death. Dinosaurs farther away for the crater died a slower death because as fires started spreading around smoke filled the air and the animals breathed in the smoke and they died.

Geologist have found the crater of the asteroid that killed off the dinosaurs. It was around 100 kilometers wide. The explosion was so big the sky was covered in smoke and the sun was not visible. It killed off all of the dinosaurs in a time span of a couple hours.

Geologist have also found a boundary in the rocks called the KT Boundary. They can tall judge the age of fossils and rocks by how far they are from the KT Boundary.

The Day The Mesozoic died

I watched a video about the dinosaurs and how they died. There was a meteorite the size of Mt Everest and it was hurdling towards Earth 20x faster than a bullet. If the meteor were to land in water then it would have made 100m tall tsunami and it would keep going until 1 month passed. They told us how the dinosaurs died and that is how.

The Day The Mesozoic Died Video Recollection

In science class over the period of about two days, we've been watching a 34-minute video about the day the Mesozoic died. It talked about these scientists who investigate this asteroids crater. When it hit it displaced a lot of laters of ground material and left a big "dent" in the earth. When it hit a lot of dinosaurs were "broiled" alive within an hour of impact. This caused big fires. These fires launched dangerous substances into the air and completely whipped out the dinosaurs ability to breathe as well as obliterated the sun! Without the sun the plants couldn't complete their photosynthesis processes and everything dependent of that was lost. 

That was a really informative video. The scientist discovered that the astroid hit and measured it and it was ten times the sizes of a atomic bomb. When the bomb hit it created a small layer of clay that divided the Mesozoic ear that the dinosaurs lived on and the cenozoic

The day the mesozoic

what happened was that there was a thin layer of unknown clay they stated to dig and they started to find fossils and then they wondered what happened and so a comet or astorid came to earth making it the animals died painfully.and people started asking what happened to the animals and why did some died and how come other animals lived? that is a mystery that no one else knowns.

The Day The Mesozoic Died

         It was about how life on earth was slowly broken over time.  The dinosaurs became exitinct over the millions of years. In the years more species came to life and roamed the earth for lots of years and the population of species started to slowly go down. Between the volcanoes erupting and the ground weathering away the envoiroment for the species became very bad and many animals lives were lost. Only certain animals still live to this day but  most of them have died and not longer are in the earth only the fossils of the animals that once roamed the earth.

The Day The Mesozoic Died

           It explains a lot in which the dinosaurs died, because of a giant meteor shower, and they got burnt into a crispy potato chip. Now lets say if they were baked with the heat of a meteor shower, than how would that impact the dinosaurs in the water very far away from where the meteors struck. Also if there was a giant water and sediment movement then wouldn't it affect where the dead dinosaur bones were laid? I understood that there was a giant meteor and it crashed into the earth making a giant tsunami, and later a death of all the dinosaurs.
