Dinosaurs have the 3 types and What are Dinosaurs?

Dinosaurs are a different gathering of reptiles[note 1] of the clade Dinosaurian. They first appeared during the Triassic period, between 243 and 233.23 million years ago (may), although the exact origin and timing of the evolution of dinosaurs is the focus of active research. The fossil record provides scant evidence about which of these groups were most closely related to dinosaurs as only traces of surviving dinosaur bodies, such as bones and teeth, have been found

.Dinosaurs Introduction

Dinosaurs are a gathering of reptiles that originally showed up around quite a while back. They became the dominant land animals after the mass extinction of the dinosaurs’ main competitors, the reptiles known as pterosaurs and large amphibians. The dinosaurs’ reign ended 65 million years ago, when a comet, asteroid, or meteor strike caused the sudden mass extinction of them and many other species of life on Earth.

Dinosaurs shapes and sizes

Dinosaurs are a varied bunch, with around 700 different species known to science. Some were as small as chickens, while others grew to be over 120 feet long from nose to tail. They come in all shapes and sizes, and scientists are still discovering new species all the time. While most people think of dinosaurs as giant lizards, they are actually more closely related to birds than they are to lizards. In fact, scientists believe that birds evolved from a group of small feathered dinosaurs known as theropods.

The Different Types of Dinosaur

s .There are many different types of dinosaurs, from small to large, herbivores to carnivores. Here is a rundown of a portion of the various kinds:-


these dinosaurs were bipedal and carnivorous. They include well-known dinosaurs such as Tyrannosaurus Rex and Velociraptor.-


these were the largest of all the dinosaurs, and are characterized by their long necks and tails. Diplodocus and Brachiosaurus are examples of sauropods.


these herbivorous dinosaurs had plates along their backs, as well as spikes on their tails. The best known stegosaurus is probably Stegosaurus itself!


These heavily armored dinosaurs were also herbivores. They are known for their clubbed tails, which they used as weapons against predators. Ankylosaurs is the most famous ankylosaur.

Dinosaur Creation

Dinosaurs first appeared on Earth during the Triassic period, around 230 million years ago. They were the dominant terrestrial vertebrates for 135 million years, from the start of the Jurassic (201 million years ago) until the end of the Cretaceous (66 million years ago), when they were succeeded by birds.

Dinosaurs are a changed gathering of creatures from ordered, morphological and natural points of view. Birds, at over 10,000 living species, are the most diverse group of vertebrates besides fish .Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. This division is mostly used for convenience; it does not reflect any fundamental difference between the two groups.

The most obvious differences between birds and other dinosaurs are that birds have feathers and wings, whereas other dinosaurs do not. Birds also have a beak instead of teeth, although some extinct species had teeth. Another major difference between birds and other dinosaurs is that birds have a keeled sternum ( breastbone), whereas other dinosaurs generally do not.

A 2015 study found that dinosaur groups share more features with each other than they do with modern reptiles, showing that they form a natural grouping, distinct from both reptiles and mammals.

Some paleontologists suggested that Dinosaurian should be split into two clades: Saurischian and Ornithischian; however this view is no longer widely accepted by researchers in
Dinosaur Extinction Theories
There are several theories about what caused the dinosaurs to go extinct. The most popular theory is that a meteor hit the earth, causing the extinction of the dinosaurs. Another theory is that dinosaurs went extinct because of a change in climate.
Theory 1: Meteor
It is believed that a large meteor hit the Earth, causing the extinction of dinosaurs. This theory is supported by the fact that there is an impact crater in Mexico that corresponds with the time when dinosaurs went extinct.

Theory 2: Climate Change Some : scientists believe that dinosaur went extinct due to a change in climate. It is thought that they were not able to adapt to the new conditions and died out as a result.

The End of Dinosaurs

Dinosaurs went extinct around 65.5 million years ago, at the end of the Cretaceous period. This was caused by a massive asteroid impact, which created the Chicxulub crater and threw so much debris into the atmosphere that it blocked out the sun and caused a global winter. Dinosaurs couldn’t survive in this cold, dark world, and they died out. Mammals, which were smaller and better able to adapt to changing conditions, took their place as the dominant land animals.

History of Dinosaurs

The History of Dinosaurs Dinosaurs initially showed up on Earth during the Triassic time frame, around quite a while back. They quickly became the dominant land animals, ruling the planet for more than 150 million years. But their time came to an end at the end of the Cretaceous period, around 65 million years ago, when a massive asteroid collision caused a mass extinction that wiped out all dinosaurs except for a few small species that gave rise to modern birds .

Dinosaurs were fascinating creatures, and we continue to learn more about them every year. Here’s a brief overview of what we know about their history. The first dinosaurs appeared during the Triassic period, which began around 250 million years ago Dinosaurs previously showed up on Earth during the Triassic time frame, around quite a while back.

This small, coyote-sized dinosaur was a meat-eater with sharp teeth and claws. The Triassic period was a time of great change on Earth. The climate was warm and dry, and there was very little plant life. This created a perfect environment for dinosaurs to thrive. They quickly became the dominant land animals, ruling the planet for more than 150 million years.

At the end of the Triassic period, Earth experienced its first mass extinction event. This was caused by a massive volcanic eruption that released huge amounts of toxic gas into the atmosphere, killing off many plants and animals. However, some dinosaurs survived and went on to thrive in the Jurassic period

Dinosaurs have the types and What are Dinosaurs?

Dinosaurs have long been a source of fascination for people of all ages. They are one of the most popular topics in children’s literature and movies, and continue to draw adults’ attention as well. Scientists have made great strides in learning about these creatures that once roamed our planet, and there is still much to learn.

One question that often comes up is: how long do dinosaurs live?

The response to this question isn’t so basic as it might appear. There are a number of factors that must be taken into account, including the type of dinosaur and its environment. Generally speaking, however, most dinosaurs lived for approximately 10-15 years. This is much shorter than the lifespan of many modern animals, such as elephants or dolphins, which can live for 50 years or more. There are a few potential explanations for why dinosaurs had such relatively short lifespans.

One possibility is that they simply grew very quickly and reached their full size at an early age. This would result in them wearing out their bodies more quickly and dying at a younger age. Another possibility is that they were more likely to be killed by predators or other factors such as disease or starvation. Whatever the reason, it is clear that dinosaurs did not enjoy the same longevity as some of today’s creatures.

What is the fattest dinosaur?

Dinosaurs are a type of reptile that lived on Earth during the Mesozoic Era. They come in many different shapes and sizes, but the fattest dinosaur is probably the supers urus. This dinosaur was so big and obese that it’s hard to believe it even existed!

The supers urus was an herbivore that could weigh up to 70 tons, which is about twice as much as the largest blue whale. Its huge size meant that it needed to eat a lot of food to maintain its weight, and it probably didn’t get much exercise since it would have been too difficult for it to move around. Even though the supers urus was the fattest dinosaur, it probably wasn’t the healthiest since its lifestyle would have been very sedentary.

Final Thoughts

There are still many unanswered questions about dinosaurs, but we continue to learn more about them every day. Scientists are constantly making new discoveries that help us understand these fascinating creatures better.

What we do know is that dinosaurs were some of the most successful animals to ever live on Earth. They ruled the planet for over 150 million years and came in an amazing variety of shapes and sizes. We can only imagine what else we might discover about these incredible creatures in the future.
