The dinosaur encyclopedia includes the duck-crowned dragon, the double-crowned dragon, the Allosaurus, the gap dragon, the Liang Long, the confused dragon, the ken dragon, the coelomosaurus, the claw dragon and the Allosaurus.

1. The duck-crested dragon

Like Tyrannosaurus rex, the duck-crested dragon appeared at the end of the dinosaur era. The most special thing about the duck-crested dragon is its head. Its flat and long jawbone looks like a duck's mouth, so it has the name of the duck-crested dragon.

2. Diplodocus

Diplodocus lived in dinosaurs in the early Jurassic. Diplodocus was 6 meters long and its head was about 2.4 meters high when standing. There are two large bone crowns on the top of the head, so it is named double-crowned dragon.

3. Allosaurus

Allosaurus, also known as Yuelong or Allosaurus, belongs to the suborder Carnivora of theropoda. It is 7-9 meters long, with a maximum of 9.7 meters, a weight of 1.5-2 tons and a maximum weight of 3.6 tons. It lived in the Late Jurassic, from 155 million years ago to 135 million years ago.

4. Cleopatra

Cleopatra was discovered in Alberta, Canada, in the 192s. Cleopatra was 9 meters long, with wrinkles on its neck and shoulders. It also had two long horns on its brow bone, a herbivore, and lived in the wetlands at the end of Cretaceous, which is now the western part of North America.

5. Liang Long

Liang Long is a dinosaur belonging to Dipteraceae. Its age can be traced back to 15 million to 147 million years ago. Its maximum length can exceed 3 meters and its weight is about 1 tons. Its nostrils are above the eyes and its neck can't be raised. Presumably, it is used to expand the original eating area.

6. Puzzled dragon

Puzzled dragon may weigh up to 26 tons, but its body length is about 21-23 meters, its neck is 6 meters long, which is actually longer than its body, its tail is about 9 meters long, and it stands about 4.5 meters high to its hips.

7. ken dragon

ken dragon lived 137 million years ago, with a total length of 4.5 meters and a height of 1.5 meters. A kind of stegosaurus, with a small head and a long body length, its hind legs are longer than its front legs. There are two rows of triangular bone plates in the front of its back and two rows of bone spikes in the back. If it is invaded by carnivorous dinosaurs, it will wave its tail and fight back with the spikes.

8. coelomonosaurus

coelomonosaurus, also known as virtual dragon, is a small, carnivorous and bipedal dinosaur in North America, one of the earliest known dinosaurs. It first appeared in the Norris in the late Triassic, about 2-3 meters long, with a hip higher than 1 meter. It is very slender and may be a good running animal.

9. Diptera

Compared with its body, Diptera's claws are really huge. It belongs to a carnivorous theropod dinosaur, named after its large claws on its forelimbs.

1. Allosaurus

Allosaurus, also known as Yuelong or Allosaurus, belongs to the suborder Carnivora of theropoda, with a length of 7-9 meters, a maximum of 9.7 meters, a weight of 1.5-2 tons and a maximum weight of 3.6 tons. It lived in the Late Jurassic, from 155 million years ago to 135 million years ago.

Brief introduction of dinosaurs

Triceratops, modern birds, and the nearest * * * ancestor of Liang Long and all their descendants. The vigorous limbs, long tail and huge body are the portrayal of some non-bird dinosaurs. They mainly inhabit forest land or open areas on the lakeshore plain.
