In 1942, a larger theropod dinosaur was discovered in the early Jurassic strata of Arizona, USA. Because it had a pair of thin V-shaped bony crests on the top of its head, scientists named it Dicrosaurus. . Dicrosaurus Dicrosaurus has a stout body, a
About 208 million years ago, a global catastrophe wiped out many species of animals. This marks the end of the Triassic Period and the beginning of the Jurassic Period. What caused this catastrophe? Scientists have proposed several explanations. Maybe, because a huge aste
Before the discovery of Eoraptor and Black Ruisaurus, Coelophysis had always played the role of the earliest theropod dinosaur. In northern New Mexico, scientists have discovered an unusually complete and perfectly preserved fossil skeleton of Coelophysis in the late Triassic strata. Their st
In the fern forest and evergreen trees beside the river and lake in the late Triassic, an Elascosaurus was strolling and eating leisurely. It did not expect that a potential disaster was already brewing nearby - two carnivorous animals. The Lili Enlong is approaching quietly.
In the late Triassic period about 230 million years ago, the first dinosaurs evolved from some reptiles. They were one of many new animal groups on land at that time. At the same time, other new forms of life conquered the skies and seas of that era. Earth in the late Tri
Triceratops is one of the world's most famous dinosaurs, known for its parrot-like beak, three facial horns and the large frill at the base of its skull. This dinosaur lived during the late Cretaceous period about 68-66 million years ago. It is the largest ceratopsian din
Shantungosaurus is a duck-billed dinosaur and the largest ornithopod ever discovered. These dinosaurs lived in the late Cretaceous period 78-74 million years ago, in what is now China. Their skulls are over 1.6 meters long. Some scientists believe Shantungosaurus was over
Giganotosaurus is another of the largest carnivorous dinosaurs. However, its exact size is difficult to calculate because we only have fragmentary remains of this predator. Some estimates suggest it was about the same size as Tyrannosaurus rex, another famous Cretaceous carnivore that lived m
In the list of the largest dinosaurs, plant-eating sauropods occupy all the top spots, but large carnivorous dinosaurs lived alongside them during the Mesozoic Era. Illustration of Spinosaurus compared to human size A reconstruction of Spinosaurus bas
Due to the large size of the fossil, scientists once thought that the Poseidon dragon bone they discovered was an ancient tree. Poseidonosaurus lived during the Early Cretaceous Period approximately 118-110 million years ago. When the first Poseidonosaurus fossils were discovered in the Unite
Puertasaurus has very few bones, as shown here, but it is one of the largest dinosaurs ever discovered. Puertasaurus had only four vertebrae, but even these fragmentary remains indicate that this dinosaur was one of the largest titanosaurs. The dorsal vertebrae found are
Visitors to Titanosaurus Patago at Britain's Natural History Museum will be able to see the dinosaur's skeleton, the first time it has been put on display in Europe. Weight: 57 tons Length: 37.5 meters Not only was the Patago tita
The largest dinosaur in the world is Titanosaurus. In fact, these prehistoric reptiles were the largest land animals that ever lived. Some dinosaurs could reach gigantic sizes. In fact, the largest are even larger than any land animal alive today! The largest dinosaurs ev
The Cretaceous is a geological period that began 145 million years ago and ended 66 million years ago. This is the last period of the Mesozoic Era. It occurred after the Jurassic and before the Paleogene—the first period of the Cenozoic Era, which is our current era. It
In the late Cretaceous period from 100 million to 65 million years ago, the dinosaur kingdom has entered its twilight period. But just as the end was approaching, many strange groups evolved in the dinosaur family. These new "actors" made the final scene of the dinosaur world extraordinarily
More than 70 years ago, in order to search for the fossils and cultural relics left by the earliest ancient humans, the American Museum of Natural History organized a large "Central Asia Expedition" to go deep into China's Inner Mongolia, Gansu and Xinjiang regions, as well as Mongolia. The l
The small tank-like dinosaur with hard armor on its body is called ankylosaurus. Various ankylosaurs combine to form a unique group in the dinosaur family, called ankylosaurs. Their taxonomic positions are Reptiles, Ornithischia, and Ankylosauria. Ankylosaurs are a relatively recent group in
Similar to the situation with sauropods, stegosaurs likely appeared in the early Jurassic. However, scientists' understanding of early stegosaurs actually began with Huayangosaurus unearthed from Dashanpu, Zigong, Sichuan, my country. Huayang Dragon 1
