How many dinosaurs are there in the world? 5, How many types of dinosaurs are there in the world?

The largest and smallest dinosaurs The longest known carnivorous dinosaur, Spinosaurus, was 16 to 19 meters long and had a mass of 16 tons. Excluding modern birds (e.g. hummingbirds), the smallest dinosaur was the size of a pigeon.

Both the theropod suborder Nearornithosaurus and the Fleuriosaurus were under 35 cm in length. The smallest known adult dinosaur specimen belonged to a nearbird and weighed an estimated 110 grams. Moreover, the smallest known herbivorous dinosaurs are Microceratosaurus and Wannansaurus, which are about 60 centimeters long.

The earliest dinosaurs The Archaeopteractosaurus found in the Valley of the Moon region of Argentina is the oldest dinosaur in history, having lived in the Late Triassic. The latest dinosaurs, ceratosaurs, were most abundant after 135 million years ago in the Cretaceous period. Largest dinosaur (terrestrial) Fragile dinosaur (58 to 62 meters long, weighing about 150 tons) Heavyest dinosaur (terrestrial) Megalosaurus (about 40 meters long, weighing about 178 tons) (Model) Qingdao dragon, the fossil was first unearthed in Qingdao.

The smallest adult dinosaur in size and weight Nearbird (body length 30 cm, weight 350 grams) Dinosaurus with the longest teeth Tyrannosaurus rex, with teeth over 30 cm. The earliest dinosaur with feathers The discovery of the world's earliest feathered dinosaur fossils in ---the Linglong Pagoda area of Jianchang County, Liaoning Province, which is about 100 million years old, is called Ornithosaurus, which is a new and international major breakthrough in the study of the origin of birds. The most expensive dinosaur fossil In 1996, the Field Museum of Natural History in Chicago, with the strong support of McDonald's and Disney, successfully won the bid for a sky-high price of $8.36 million to buy the fossil of the Tyrannosaurus rex, Sue.

The fattest dinosaur in China.

Ruyang Yellow River dragon fossil, this is currently the most "fat" dinosaur known in China. The Ruyang Yellow River Dragon is about 20 meters long, and the middle part of the hip bone is less than half a meter high, but it is as wide as a meter, and the 123-centimeter-long shoulder blade can reach 83 centimeters at its widest point.

In 1824, it was thought that there were 800 species of dinosaurs, which could be classified into 540 genera. Later, scientists only recognized 336 species of about 280 genera as true dinosaurs. There are 40 genera in the United States, 40 in Mongolia, 36 in China, 31 in Canada, 26 in the United States (minor), and 23 in Argentina.

The dinosaurs in the world are:

1. Tyrannosaurus Rex:

Tyrannosaurus rex, also known as Rex Tyrannosaurus, lived in the Maastricht period at the end of the Cretaceous period, about 68.5 million to 65 million years ago, and was one of the last non-avian dinosaur species before the Cretaceous-Tertiary extinction event.

2. Protodontosaur:

Protodontosaurus is a suspicious dinosaur of the theropod suborder that lived in Lower Cretaceous China and Mongolia. There are currently three known species, all of which are fragments with only teeth.

3. Construction of air dragons:

Jianshe Airosaurus is a small Jurassic carnivorous dinosaur with a body length of 4 meters and a weight of about 130-140 kilograms. Its main characteristics are a large and light head, dagger-shaped teeth with flat and sharp teeth, a short neck, a long tail, short and flexible forelimbs, strong and powerful hind limbs, sharp claws at the end of the toes, and good at running fast on both feet.

4. Petroleum Karamayron:

Oil Karamay is a species of theropoda, carnivorous suborder, Allosauridae, and Karamay. Carnivorous, about 13 meters long, lived in the early Cretaceous period.

5, Gan's Sichuan Dragon:

The Sichuan dragon is a dinosaur belonging to the family Sinoraptoridae. It lived in Asia during the late Jurassic period. It resembles a small Allosaurus in appearance, weighing about 100-150 kilograms and measuring about 8 meters in length.

Meet 12 different species of dinosaurs, Tyrannosaurus rex, Parasaurus, Carnotaurus, and Velociraptor.

The dinosaurs in the <> world include Aeolian Wing, Triceratops, Tyrannosaurus rex, Microraptor, Ornithosaurus, etc.

1. Aeolus pterosaur: Aeolus pterosaur is a pterosaur, also known as a pterodactyl, which lived in the Late Cretaceous period (Campan order to Maastricht order), about 84 million to 65 million years ago. With a wingspan of over 11 meters, it is the largest flying animal known to man.

The Pterodactylidae are advanced and toothless pterosaurs. The name ** is the Aztec civilization of the Queztec god of the Queztec Queztec.

2. Triceratops: Triceratops is a genus of herbivorous dinosaurs in the Ceratosauridae family, a giant four-legged herbivorous dinosaur. In full adulthood, the total length is about meters, the hip straightening height is about meters, and the general weight is 9-18 tons, and the heaviest is more than 20 tons.

The fossil was found in the Late Cretaceous Late Maastricht Terrace strata of North America, about 65 million years ago.

3. Tyrannosaurus rex: Tyrannosaurus rex is the Rex Tyrannosaurus rex, which is the largest one in the tyrannosaur family. The body length is about meters. The average hip height is about 4 meters. The highest hip height can reach about meters, and the highest head height is nearly 6 meters.

4. Microraptor: Microraptor means small thief, which is a small dinosaur found in the Jiufotang Formation of Liaoning Province, China, which lived in the early Cretaceous Balliem Order, that is, about 130 million to 125.5 million years ago, and nearly 10 complete fossils have been found.

5. Avian dragon: Avian dragon, which means the teeth of the iguana, belongs to the order of the sauromorph bird hip bird. Ornithosaurs were large ornithopod dinosaurs, about 9 to 10 meters long and 4 to 5 meters tall, with a pointed claw on the thumb of the forehand that probably used to resist predators.
