What were the dinosaurs of the Cretaceous period?

In the age of giant dinosaurs, there were monsters more terrifying than dinosaurs in the Cretaceous period.

9 Dinosaurs from the Cretaceous period.

1. Aeolian pterosaur.

Aeolian pterosaur is a pterosaur, also known as the Veloped Snake Pterodactyl, which lived in the Late Cretaceous period (Campan to Maastricht), about 84 million years ago to 65 million years ago, the Aeolian pterosaur has a wingspan of more than 11 meters long, and 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 feathered serpent.

2. Triceratops.

Triceratops is a genus of herbivorous dinosaurs of the ceratosauridae family, a giant four-legged herbivorous dinosaur, with a total length of about meters and a straightened hip height of about meters when fully adult, generally weighing 9-18 tons, and the heaviest weighing more than 20 tons. The fossil was found in the Late Cretaceous Late Maastricht Terrace strata of North America, about 65 million years ago.

Triceratops is one of the latest plant-eating dinosaurs, and it is also the most powerful plant-eating dinosaur, so it is regarded as a representative of Late Cretaceous dinosaurs. There are currently 2 valid species: Triceratops dreads, but there are other genera that have been named.

Triceratops is also a well-known dinosaur in popular culture.

3. Tyrannosaurus rex.

Tyrannosaurus rex, also known as Rex Tyrannosaurus, is the largest species of the Tyrannosaurus 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.

The average weight is about 9 tons, (the ecological average is about a ton), the heaviest tonnage, and the head length is about a meter. The bite force is generally 90,000 Newtons - 120,000 Newtons, and the end of the mouth can reach a maximum of about 200,000 Newtons, and it is also the thickest carnivorous dinosaur.

Some scientists believe that the Asian Warrior Tyrannosaurus was the first effective species of the Tyrannosaurus superfamily. Tyrannosaurus rex lived in the Maastricht order 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 extinction event of the Tertiary in the Cretaceous. The fossils are found in the United States and Canada in North America and are among the last Cretaceous dinosaurs to become extinct.

4. Microraptor.

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

Raptors were one of the smallest carnivorous dinosaurs in the world, living hundreds of millions of years ago in the Early Cretaceous. Microraptors were also one of the first dinosaurs to be found to have feathers and wings. It is common to have a body length of about 60 cm, but its body is the size of a pigeon, and it has sharp claws and limbs covered with feathers.

5. Avian dragon. Ornithosaurus, which means tooth of iguana, belongs to the order Ornithosaurus of the sauromorph ornithischia. 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.

They mainly lived in the early Cretaceous from the Van Lanjin to the Barem Order, about 140 million years ago to 120 million years ago; The age of survival is about the middle of the process from the first appearance of the agile Lardontosaurus to the most abundant duck-billed dinosaur in the order of Ornithischia. Ornithosaurus is the second officially named dinosaur in the world after Spotatosaurus.

9 Dinosaurs from the Cretaceous period.

Cretaceous dinosaurs include: Rex Rex, Brute Dragon, Maprosaurus, Australopinosaurus, and Salodontosaurus.

1. Tyrannosaurus rex.

Tyrannosaurus rex was not only the strongest predator at the end of the Cretaceous period, but also became the most ferocious species of all carnivorous dinosaurs with its huge size and strong bite force, with a maximum body length of meters and a strong bite force of 200,000 Newtons, making it a well-deserved king of dinosaurs.

2. Brute Dragon. Barbarian dinosaur is the largest carnivorous dinosaur in North America, born at the end of the Jurassic period, survived until the early Cretaceous period, the maximum body length can reach meters, and the bite force can reach as much as 15 tons, only inferior to the Tyrannosaurus rex, a single tooth can grow to a centimeter long.

3. Maprolong.

Maprosaurus is currently the fourth largest carnivorous dinosaur, the largest estimated body length reached meters, appeared at the end of the Cretaceous period, is considered to be able to rival the existence of Tyrannosaurus rex, although the teeth are small, but the sharp socks are sharp like blades, has a very strong hunting ability.

4. Southern Giant Dragon.

Australopithecus and Maprosaurus belong to the same family of sharkodontosaurs, and is one of the largest carnivorous dinosaurs found in South America, with a body length of up to 20 meters, teeth up to 20 centimeters long, like a dagger pointed and thin, able to easily cut and pierce the prey**, so it is called one of the ten strongest dinosaurs in the Cretaceous.

5. Sharkodontosaurus.

Sharkodontosaurus flourished mainly in the middle to late Cretaceous period, with the largest body length reaching 14 meters, and its weight remained at a ton, with sharp teeth similar to those of modern man-eating sharks, but with a small brain capacity and less intelligence.

Cretaceous. The largest dinosaur was Puertasaurus, which was 35-40 meters long.

Puertasaurus (Puertasaurus) is a genus of sauropods that lived in Patagonia during the Late Cretaceous period.

The type species Rui's Pultasaurus (P. Ritford'sReuili) is named in honor of Pablo Puerta and Santiago Reuil, who jointly discovered the fossil of Puerta in January 2001. The fossil of Pultasaurus has only part of the vertebrae.

The orthotyped specimen of Pultasaurus contains four cervical, dorsal, and caudal vertebrae.

And their dorsal vertebrae are meters in length and meters in width. This is the widest known sauropod vertebrae with filial piety. Paleontologist Fernando Novas deduced that Pultasaurus was 35 to 40 meters (115 to 131 feet) long and weighed 80 to 100 tons.

If this reasoning is correct, Pultasaurus would be one of the largest dinosaurs, alongside Argentinosaurus.

Fairly. The discovery of Pultasaurus also extended the survival period of giant sauropod dinosaurs; They lived in Patagonia at the end of the Cretaceous period, about 70 million years ago in the Early Maastricht Order. Pultasaurus belongs to the evolutionary clade of the Titanosaurus class.
