What are the names and characteristics of dinosaurs?

Tyrannosaurus Rex, also known as Tyrannosaurus Rex, belongs to the Tyrannosaurus Rex family, and its name means cruel lizard king. It is one of the largest carnivores in history and the most famous carnivorous dinosaur. It is one of the latest species of dinosaurs, with a body length of12 ~14m and a longest length of15m. The average hip height is 3.6 meters, and the highest is 4. 1 meter. The average height is 5. 1m, and the maximum height is 6m (from the ground to the head). The average weight is 9 tons, the maximum weight is 14.85 tons, and the head is 1.55 meters. The bite force ranks first among terrestrial creatures and carnivorous dinosaurs (the bite force can reach 20 tons), and it is also the strongest carnivorous dinosaur.

Shanglong

Shanglong is an extinct marine reptile, belonging to the family Shanglong, which lived in the late Jurassic. Shanglong is a large carnivore that feeds on fish, squid and other marine reptiles. Before it was officially named, Shanglong was called a "monster". They were advanced predators in the ocean during the Jurassic period about 2-65438+45 million years ago. Shanglong was first discovered in Polypodiaceae, mainly contributed by richard owen. He studied this animal in 184 1 and named it Shanglong.

Spinosaurus

Spinosaurus (Latin name: Spinosourus, meaning "lizard with thorns") is the largest known carnivorous dinosaur and theropod dinosaur, with a body length of 18~22 meters, a sail height of 2 meters and a hip height of about 5 meters. At present, the largest individuals IPHC 19 12-x and MSNM V 4047 are conservative in weight. Distribution areas include North Africa, Morocco, Algeria, Libya, Egypt, Tunisia, and possibly Western Sahara, Niger and Kenya. At present, there are two kinds of spinosaurus, the most famous one is the Egyptian spinosaurus found in Egypt, and the second one is the Moroccan spinosaurus found in Morocco. Moroccan spinosaurus was very small, while Egyptian spinosaurus was very big. Spinosaurus was discovered by German paleontologist Ernst Strom in Egypt and described in 19 15. The original specimen was destroyed in Germany during World War II, so its fossils are very precious.

diplodocus

Liang Long (scientific name: Liang Long) is a dinosaur belonging to Diplodocus, and its skeleton fossils were first discovered by samuel wendell williston. Liang Long lived in the western part of North America at the end of Jurassic, from1500,000 years ago to1470,000 years ago. The longest individual can exceed 30 meters and weigh about 10 ton. Noses are above the eyes. Their necks can't be lifted, and they should be used to expand the eating area in situ.

brontosaurus

Dipteraceae Puzzled Dragon, including Ajax Puzzled Dragon (A. ajax) and Lushi Puzzled Dragon (A. louisae). Weighing 30 tons, according to the newly discovered dinosaur thigh bone in Argentina, it is 20 to 30 meters high and about 35 meters long. This dinosaur weighs 15500 pounds (about 7 tons) than the largest creature ever discovered. But Lei Long is a moderate herbivore. The back half of its body is higher than its shoulders, but when it stands on its hind heel, it really seems to fly into the sky. It may live in plains and forests or walk in groups.

pterosaur

Pterosaur, also known as pterosaur, is an extinct reptile with nearly 100 species. [1] Although living in the same era as dinosaurs, pterosaurs are not dinosaurs, which means "winged lizards" in Greek, but an evolutionary branch of flying reptiles. It lived from the late Triassic to the late Cretaceous, about 228 million years ago to 65 million years ago. Pterosaur was the first vertebrate to fly. Pterosaur's wings came from the skin film between the side of the body and the four phalanges of the wings. Early species had long jaws and long tails that covered teeth; Later species greatly shortened their tails and lacked teeth. Pterosaur's body shape has changed greatly, from the forest pterosaur of birds to the largest flying creatures that have appeared on the earth, such as Fengshen pterosaur and Hazgo pterosaur, with a wingspan of more than 12 meters, teeth as long as 10 cm and a huge and sharp mouth.

Horned dragon

Sharodontosaurus (scientific name Carcharodontosaurus), also known as odontosaurus, means "lizard that eats human sharks", belonging to theropod sharks, which lived from the middle to the late Cretaceous1100,000 to 93 million years ago, and from the Albian period to the Toulon period of the Cretaceous. Squaodon is a huge carnivorous dinosaur, and it is also one of the largest theropods and carnivorous dinosaurs found so far. It is estimated that adults can reach 12.5 meters, and the largest even reaches 14.6 meters long and weighs 6 tons to 12 tons. Its size surpassed that of Oshara Dragon, Khyron Dragon and Sietzlong Dragon. The main features include: extremely sharp shark-like teeth, long teeth, pre-orbital foramen as big as cranial eyes, short forelimbs, huge and long skull, narrow nose and mouth, thin trunk and slightly short hind limbs.

Triceratops

Triceratops is a medium-sized quadruped dinosaur, with a total length of about 7.9 to 10 m, a hip height of 2.9 to 3 m and a general weight of 4 to 6 tons. They have a very big head shield and three horns, which reminds people of modern rhinos. Although no complete triceratops bones have been found, they are still famous for a large number of partial skeleton specimens found from 1887. For a long time, there has been a debate about the role of their three horns and head shields. Traditionally, these structures have been regarded as weapons against predators, but today's theory holds that these structures may be used for courtship and dominance, just like the horns of modern reindeer, goats and unicorns.

stegosaurus

Stegosaurus is a huge dinosaur, a herbivore, living in the late Jurassic and early Cretaceous. It has a row of huge bone plates on its back and a dangerous tail with four thorns to resist predators. It is about 12 meter long, 7 meters high and weighs 4 tons.

People think that they live on the plains and live together with other herbivores (such as Liang Long) in a nomadic way.

Dinosaur (English name: dinosaur) is a reptile that appeared in Mesozoic (Triassic, Jurassic and Cretaceous). Its vigorous limbs, long tail and huge body are the portrayal of most dinosaurs. They mainly inhabit woodland or open areas in lakeshore plains (or coastal plains).

184 1 year, British scientist richard owen [2]? When studying several fossils that look like lizard bones, I think they were left by some prehistoric animals and named them dinosaurs, which means "terrible lizard".

The sudden disappearance of dinosaurs at the end of Cretaceous 65 million years ago became a mystery in the evolutionary history of life on earth. This mystery has not been solved so far. In the past, all living things on the earth were recorded in fossils. Many dinosaur fossils have been found in Mesozoic strata. A large number of bones or various shapes can be seen in it. However, in the subsequent Cenozoic strata, there were no fossils of non-bird dinosaurs at all, thus inferring that non-bird dinosaurs died out together in Mesozoic, and now only birds are left. Most scientists agree that "birds belong to dinosaurs".

There are many kinds of dinosaurs, and their shapes and habits are very different. The largest fragile double-chambered dragon may be more than 50 meters, while the smallest hummingbird may be less than 10 cm. As far as eating habits are concerned, there are docile herbivores and fierce carnivores, as well as omnivorous dinosaurs who are both vegetarian and vegetarian. Ruled the earth for about 80 million years (654.38+44 million years ago-65 million years ago).
