Do you want to know more about dinosaurs, the Jurassic period, and the Cretaceous period?

The word Mesozoic means 'middle life,' and this was the period of dinosaurs. This epoch encompasses the Triassic, Jurassic, as well as late Cretaceous phases.

This period experienced a tremendous meteor strike that resulted in a mass extinction or a Permian extinction event, eradicating dinosaurs and approximately 80% of life on this planet. Non-avian dinosaurs existed between 245 and 66 million years ago, during the Mesozoic era. This occurred tens of millions of years prior to the first modern humans, called Homo sapiens, that have been on the Earth for the longest period.

The Mesozoic era is divided into three periods by researchers: the Triassic, Jurassic, and Cretaceous. During this time period, the ground progressively separated from one massive landmass into smaller pieces. During the Triassic period, all continental plates were part of a common land surface known as Pangaea.

This simply means that the distinctions between animal life or plants discovered in different parts of the world were minimal. The weather was comparatively warm and muggy, and huge deserts encased much of the territory. There were almost no polar ice caps, as there are today. Reptiles known as dinosaurs first emerged in this atmosphere. Reptiles thrive in hot environments because their skin is far less porous than the skin of mammals.

Mammals have porous skin and perspire to cool themselves. Dinosaurs, unlike mammals, had cold blood, which allowed them to lose less water in the heat. Reptile kidney functions are also superior at water storage.

Even though the super-continent that was named Pangaea did exist all through the Triassic, the pressures that created it started to pull it apart almost instantly. Pangaea actually started to oscillate, with different pieces spinning at different rates and in different paths. The strained relations ended up causing the continent to start tearing, and the Earth slumped down into these fissures, and thus they formed rift basins. These rift basins formed during the Triassic period between North America and Europe, as well as between Africa and South America.

Such basins would become the Atlantic Ocean and the Gulf of Mexico while they proceeded to separate all through the late Jurassic Period. Numerous different rifts later formed, separating Antarctica, India, and Australia. Toward the close of the Triassic period, a series of explosions and humongous volcanic activity ended up causing Pangaea to gradually split in two.

The North Atlantic Ocean was formed at this time. There had been a major catastrophe at the end of the Triassic period, the reasons of which are still being discussed. Numerous large land creatures were wiped out, and yet dinosaurs managed to live, allowing them to grow and develop into a broad range of forms and rise in population. Pangaea, the solitary landmass, separated, forming Laurasia in the north and Gondwana in the south.

During most of the Triassic period, the weather was toasty, with a parched continental inner surface and no scientific proof of ice at either of the poles. Following the Permian annihilation, many new types of animals and dinosaurs evolved during the Triassic period.

This created a lot of dinosaur diversity. Reptiles were the dominant land animals. Dinosaurs evolved along with marine life like reptiles, lizards, and tortoises that first appeared. Mammals first emerged during the Triassic period, but they were unimportant until their predators, dinosaurs, went extinct at the end of the Cretaceous period.

Crocodiles were plentiful. During this time, insects underwent a complete metamorphosis. Temperatures dropped slightly, but it was still warmer than the climate and temperature we have today because there was a huge amount of carbon dioxide present in nature.

After reading about the Triassic period, the Cretaceous period, and the Jurassic period when Tyrannosaurus rex ruled the Earth, also read about the Brazil museum and Azerbaijan facts.

Different Types Of Dinosaur Periods

Dinosaurs flourished during the Mesozoic era. This era is divided into three periods. They are named the Triassic, Jurassic, and Cretaceous periods. All these three periods held many changes for dinosaurs. Each one had a different event that impacted dinosaurs.

Following the Triassic period, dinosaur transformation was influenced by changes in vegetative cover and the placement of continents. During the late Triassic and early Jurassic periods, the landmasses were joined as a single landmass called Pangaea, and there was global dinosaur wildlife dominated by Coelophysis carnivores and initial Sauropodomorph herbivorous dinosaurs.

In the late Triassic period, gymnosperm crops, especially conifers, a promising food source, were introduced. Because early Sauropodomorphs lacked sophisticated mechanisms for digesting their food in their mouth, they must have relied on other methods of the breakdown of food further along with the digestive system.

Rainfall increased during the Jurassic period so sea levels started rising between land areas. Crops like ferns as well as horsetails were able to spread across large areas as a result of these variations. Some of this greenery was converted into the coal and oil that we use nowadays.

There were also woodlands of towering conifer trees like sequoias and monkey puzzles. The breakup of Pangaea kept going, and the early Atlantic Ocean and the Gulf of Mexico emerged as shallow continental seas.

Warm tropical greenhouse conditions occurred all over the world. Giant plant-eating dinosaurs walked the Earth, pursued by relatively small dinosaurs but violent carnivores.

This simply means that the distinctions between animal life

Different Types Of Dinosaur In Dinosaur Periods

The range of estimates varies, but approximately 300 legitimate taxonomic classification and 700 valid species of extinct non-avian dinosaurs and avian dinosaurs have been unearthed and identified. All dinosaurs were wiped out in a mass extinction.

However, because dinosaurs' fossil records are inadequate, in the context that scientists have still yet to explore fossils of other types of dinosaurs which no doubt did exist, these figures do not accurately represent the true uniqueness of prehistoric dinosaurs.

One reason for the fossil record being incomplete is that rocks from certain geomorphic periods of time are not typically found on the planet's surface. The shape and size of non-avian dinosaurs, which are now extinct dinosaurs, varied greatly.

Here are some dinosaurs that lived during the middle Triassic period. The Coelophysis Bauri was an 8-10 ft (2.4-3 m) long, light, nimble dinosaur. The Plateosaurus Engelhardt wasn't really as large as its leviathan subsequent family members, such as the Apatosaurus and the Barosaurus, but it was quite large for an early representative of the dinosaurian bloodline, with a body measuring about 25 ft (7.6 m) long. Duck-billed dinosaurs had a mouth in the shape of a beak.

Allosaurus fragilis were fearsome carnivorous dinosaurs and one of the late Jurassic's apex predators. Barosaurus dinosaurs were plant-eaters and extremely long-necked members of the sauropod dinosaur gang, which typically stayed on four, durable, column-shaped legs and feet. They were one of the largest dinosaurs.

The Mamenchisaurus was a medium-sized Sauropod dinosaur with an adult length of 60 ft (18.3 m) and a shoulder height of 11 ft (3.4 m). Even though the late Jurassic period is known best for its dinosaurian goliaths such as the Apatosaurus, the Stegosaurus, and the Allosaurus, relatively small varieties such as the pint-sized Ornitholestes scurried under them unnoticed.

Some Cretaceous period dinosaurs included the Albertosaurus. It was a close, slightly smaller cousin of the Tyrannosaurus rex and was a powerful and intimidating carnivore in its own right. The Ankylosaurus was an early Cretaceous period armored reptilian tank that resembled mammal-like reptiles and their relatives, Glyptodonts.

Avian dinosaurs and birds that we see today have a common ancestor and are considered living dinosaurs.

How big was the tsunami that killed dinosaurs?

New research revealed that the meteor that was believed to have killed dinosaurs actually created a huge wave that was at least 52 ft (15.8 m) in height.

Dinosaurs were drowned under this huge wave. The tsunami was said to be caused by a huge meteor that fell from the sky to the Earth. The meteor is said to have been the size of Manhattan and even its residue was large enough to create huge waves that could easily drown even the biggest of dinosaurs.

The impact created a huge gap in the sea which caused these waves to occur. There have been countless theories about how dinosaurs were actually wiped out from the Earth, but recent studies show that it was mostly because of a huge tsunami that was caused by the meteor.

Did dinosaurs live on Pangaea?

Dinosaurs have been on all continents. Thus, it is safe to say that during the Triassic period, there were dinosaurs living on Pangaea.
