Transcript of CRETACEOUS LAND
If this actually did happen then most dinosaurs would have died from the asteroid strike,lack of food,or the environment change. The good part is that the dinosaurs could have tried to hide in a hole or deep cave because the strike might not have gotten them. They also could have gone deep into an ocean of some kind. There were many ways they could have survived,but most of the dinosaurs were not smart enough to be aware of what was going on. Extinction DINOSAUR LOOK ALIKES Dinosaurs from the Cretaceous Period look a lot like the reptiles we see every day but what about humans? Most dinosaurs were larger than the average human. The dinosaurs had to have a defensive strategy and an offensive one too. Most humans have them too but we don't have sharp scales, giant sharp teeth, wings or the size of an elephant. Humans look almost opposite from a dinosaur in the Cretaceous Period.
Humans have soft skin and can not always fight back, but they have the instinct to run away from what ever bad is happening. A lot of dinosaurs have that instinct too. Dinosaurs from the Cretaceous Period look almost nothing like humans but their natural reactions are very similar. Most dinosaurs have a defensive and an offensive way to survive. When the dinosaurs are at war there are many crazy events that go on. In the ocean there are many many problems and solutions. For example the Mososaurus would swim after the prey. If the prey were a Ammonite( a very fast fish in a small shell ) it would use its tenticals to swim very fast away from the giant sea creature.
The Mososaurus would use its massive fins to catch the small fish and eat it. Only sometimes would the small Ammonite be able to get away. The problem is that the Ammonite swims away as fast as it can. The solution is the big Mososaurus would swim fast and catch the small fish. CRETACEOUS ISLAND WELCOME TO BY AIDAN FISH EVOLUTION Lots of things live in a lot of places like the desert or the icey cold forests. The Cretaceous period was the time noted for being'' the last part of the age of the dinosaurs". During the Cretaceous Period the continents moved apart, many of them looking like the continents we have today. Since there were so many continents there was going to be a more varied climate. The animal life was not the same on every continent as the groups of animals were evolving in there own way. So, the creatures in North America were not the same from the dinosaurs in South America.
The dinosaurs of the world about 45 to 65 million years ago lived in very different places and continents. During the Cretaceous Period, flowering and other plants started to evolve. Creatures with good chewing mechanisms, like the Corythosaurus, could go from eating parts of trees to grass on the ground. This made plants evolve with seeds that could survive a lot. Evolution changed a ton during the Cretaceous Period. Extinction WORK CITED World book, Dinosaurs by David Burnie, www.historyforkids.org, www.enchantedlearning.com, www.bobspixels.com, http.webspinners.com, www.lifestudiesonline.com LIFE IN THE WATER PANGEA About 130 million years ago, the Jurassic period was just ending and the Cretaceous period was just beginning. The breaking-up of Pangaea (when all the continents were together) was soon going to happen.
Eurasia and North America had started to come together and so had South America and Africa. Two attached land forms make up Pangaea. The Southern land mass was called Gondwanaland. It contained the continents South America, Africa, India, Australia, and Antarctica.
The top half of Pangaea contained North America, Europe and Asia. It was called Laurasia.
A German man named Alfred Luther Wegener believed that his theory of continental drift happened. His and many theories could be right because Pangaea was a very weird place and the sequence of what happened was also very odd. THE JURASSIC PERIOD WAS JUST ENDING. GONDAWANALAND WAS JUST STARTING TO FORM. DIRECTLY NORTH LAURENTIA WAS JUST STARTING TO FORM TOO. LAURENTIA COLLIDED WITH BALTICA AND MADE LAURUSSIA. THE LAND MASSES CONTAINED THE NORTHERN CONTINENTS. MEANWHILE GONDWANALAND WAS TRAVELING WITH ALL THE SOUTHERN CONTINENTS. LAURUSSIA JOINED WITH GONDWANALAND. PANGAEA WAS CREATED AND STAYED ONE GIANT CONTINENT FOR A LONG WHILE. ONCE AGAIN PANGAEA BROKE UP INTO 7 DIFFERENT CONTINENTS. IT FORMED THE 7 CONTINENTS WE HAVE TODAY. AT THE START OF THE PALEOZIC ERA GONDWANALAND WAS A SUPER CONTINENT. LAURENTIA AND BALTICA COLLIDED TO MAKE LAURUSSIA. GONDWANALAND CONTAINED THE SOUTHERN CONTINENTS AND LAURUSSIA CONTAINED THE NORTHERN CONTINENTS. EVENTUALLY THEY BOTH COLLIDED AND MADE PANGAEA. PANGAEA STAYED A SUPER CONTINENT FOR A LONG TIME AND THEN BROKE AND FORMED THE CONTINENTS WE HAVE TODAY. 1. How many years ago was the Cretaceous Period?
It was 144 to 65 million years ago.
2. What are three theories on how the Cretaceous Period ended?
One is the asteroid theory, another is the glasier theory, and another is the break up of the continents.
3. What was the Continental Drift during the Cretaceous Period?
It was when the continents drifted away from each other.
4. What were the names of the two continents in the early Cretaceous Period?
Gondwanaland and Laurasia.
5. What type of animals dominated the Cretaceous Period?
The reptiles dominated because there were a lot of them.
6. What are the names of 3 dinosaurs that lived in the Cretaceous Period?
The Iguanodon, the Baryonyx and, of course, the T-rex.
7. What was the climate like during the Cretaceous Period?
The climate was very hot and muggy.
8. Which dinosaur ruled the Cretaceous Period?
The T-rex was the king back then.
9. What was the most important botanical discovery during the Cretaceous Period?
The Cretaceous Period had the first flowering plants.
10. What did the swamps and bogs from the Cretacous Period become today?
They turned into the coal we have today. HELLO, MY NAME IS AIDAN FISH AND THIS IS AN AMAZING REPORT ABOUT THE CRETACEOUS PERIOD.
ENJOY. QUESTION AND ANSWER In the Cretaceous Period there were very weird looking creatures to humans. Most of them had to have colors and textures that would blend in with their background so that predators wouldn't see them. Camouflage was very important back then. Just in case the predator saw the prey, the prey would need a good defense because if it didn't, they would probably get eaten.
As for the predators, they would need to act like a tiger. Stay low, and when the prey is close, ATTACK!!
The most common color of a camouflaged dinosaur is just plain gray for big animals like cretaceous elephants and rhinos. However the smaller dinosaurs were brightly colored. The bold colors of the small dinos helped them blend in with their backgrounds and it made it easier to attack. The small dinosaur called the Coelophysis had a very good experience doing this. Textures and the actions of all dinosaurs really count. THE PAST IS BACK AND FILLED WITH DINOSAURS THE END This is the Coelophysis, a dinosaur known for its textures and camouflage.
