Dinosaurs taxonomically belong to: Animalia,Vertebrate phylum, reptiles, sauropods (e.g., herbivorousBrontosaurus) and ornithischian (e.g., carnivorousLeaping Dragon
To facilitate research, dinosaurs can be divided into avian and non-avian dinosaurs. Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic.
and Cretaceous), all of which became extinct 65 million years ago. This entry mainly introduces non-avian dinosaurs.
The muscular limbs, long tails, and massive bodies are some of the non-avian dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).
Morphological characteristics:
Dinosaurs as a whole were huge. By the standards of dinosaurs, sauropods are large animals. In the long age of dinosaurs.
Even the smallest sauropods are larger than the rest of their habitat, while the largest sauropods are orders of magnitude larger than any animal that appears on the surface.
Most dinosaurs were much smaller than large sauropods. Available evidence suggests that the average size of dinosaurs varied during the Triassic, Early Jurassic, Late Jurassic, and Cretaceous periods.
Most theropod dinosaurs weighed between 100 and 1000 kilograms, while most Holocene predatory carnivores weighed between 10 and 100 kilograms. Most dinosaurs are estimated to weigh between 1 and 10 tons. A study by the National Museum of Natural History in London found that the average dinosaur weighed about 100 kilograms, while a new generation of mammals was born.
The average weight is between 2 kg and 5 kg.

Dinosaurs are taxonomically reptiles. Dinosaurs refer to the nearest common ancestor of Triceratops, modern birds, and Diplodocus and all of their descendants. The Jurassic and Cretaceous periods were the thriving periods of giant reptilian dinosaurs.
Not only are the individuals very large, but they are also very specialized in body shape and even diet, and they mainly inhabit woodlands or open areas on the lakeshore plains (or coastal plains).
The biggest difference between dinosaurs and other reptiles:Due to their standing posture and the way they walked, dinosaurs had a completely upright posture, with their limbs built directly below their bodies. This structure is more advantageous for walking and running than other types of reptiles, such as crocodiles, whose limbs are stretched outward.

Dinosaurs belong to the category of reptiles.
Dinosaurs are a general term for a class of reptiles that appeared during the Mesozoic era, and most dinosaurs are portrayed by their athletic limbs, long tails, and large bodies. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains). There are probably more than 1,000 species of dinosaurs living on Earth, but the age of dinosaurs.
They are so far away from us that they can only be understood through the fossils that have been discovered.
Breeds of dinosaurs.
1.Tyrannosaurus rex (non-avian dinosaur that survived to the last).
Tyrannosaurus rex, or Rex Tyrannosaurus, lived in the Cretaceous period.
At the end of the period, it was the Cretaceous and Tertiary extinctions.
One of the last non-avian dinosaur species before the event. Fossils are found in North America.
The United States and Canada were among the last dinosaurs to become extinct. Tyrannosaurus rex is the largest of the Tyrannosauridae family, with a body length of about one meter.
2.Fragile two-chambered dragon.
The largest known dinosaur).
The Fragile Dicolucisaurus was the longest and heaviest dinosaur in history, and even weighed more than a blue whale. It is up to 35 meters long, and Diplodocus.
There is a close relationship.
3.Ankylosaurus dinosaurus (dinosaur with armor).
The body length of the dorsal ankylosaurus could reach 10 meters, and the body was wide and the neck was short; stubby, strong limbs; The feet are short and wide, with 5 fingers on the front foot and 4 toes on the hind foot, and hoof-like claws at the end of the fingers (toes), which are suitable for land activities. Ankylosaurus is often considered the ancestor of armored dinosaurs. It is characterized by a carapace body and a large vertebral tail.

Dinosaurs are taxonomicly classified as chordates, sauriformes, bipore, ornithischians, sauropods, main dinosaurs, and dinosaurs. The history of human discovery of dinosaur fossils has a long history, dinosaur fossils have existed on the earth for tens of millions of years, and the term "dinosaur" was coined by British paleontologist Richard Owen.
Biologists divided dinosaurs into avian and non-avian dinosaurs for ease of study, and avian dinosaurs only lived in the Mesozoic Era, and all of them became extinct 65 million years ago. Bird dinosaurs, with sound limbs, long tails, and large bodies, mainly inhabit forests and open areas on the lakeshore plains.
The discovery of dinosaur fossils has a long history. Long before the Mantels discovered the avian dragon, Europeans knew that there were many gigantic skeleton fossils buried underground. However, at the time, people did not know their exact attribution, so they were always mistaken for "the remains of giants".
It wasn't until Mr. and Mrs. Mantel discovered the avian dragon and compared it to the iguana that the scientific community initially determined that it was a lizard-like and long-extinct reptile. As a result, new types of dinosaurs and other ancient reptiles were discovered with names related to lizards, such as "whale-like lizards", "forest lizards", and so on.
At the same time, because the fossils of these ancient animals that first attracted people's attention are often huge and strangely shaped, it is really terrifying.

Dinosaurs are sauriformes of the phylum Chordates. Dinosaurs are scaly descendants of reptiles, dinosaurs lay hard-shelled eggs, stand with legs sticking vertically from under their bodies, rather than from the sides like crocodiles, and, at least, some dinosaurs still have feathers. Today's birds and dinosaurs have many characteristics that are very similar, so we also believe that birds are descendants of dinosaurs, and birds are the dinosaurs of the past.
Distribution of dinosaursDinosaurs have ruled the earth for hundreds of millions of years, and dinosaurs have existed on almost every continent.
The distribution of dinosaurs on 7 continents: 269 species in Asia, 169 in North America, 126 in Europe, and South America.
101 species, 66 species in Africa, Oceania.
19 species, 4 species in Antarctica.
Already in China, the USA, Argentina, Mongolia.
United Kingdom, Canada, France, Australia, Portugal, Brazil, Germany, South Africa.
Niger, Spain, Morocco.
Romania, India, Madagascar, Thailand, Tanzania, Egypt, Pakistan, Russia, Uzbekistan, Austria.
Dinosaurs have been found in Belgium and other 52 countries or regions.
