The carnivorous theropod dinosaurs also survived the catastrophe at the end of the Triassic and further developed in the Jurassic. The Synanthosaurus discovered in Zimbabwe that lived 200 million years ago was a theropod carnivorous dinosaur that dominated the earth in the early Jurassic peri
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
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
1. Early ornithopod dinosaurs Compared with the numerous representatives of sauropod dinosaurs in the late Triassic, very few ornithischian dinosaurs were discovered at that time. They are really rare. Skull, mandible and teeth of Heterodontosaurus
Early paleontologists believed that dinosaurs were a class of reptiles of their own, so they were unified into the "order Dinosaurs". Later, as scientists learned more about these animals, they discovered that they actually included two different orders of reptiles, namelySaurischians (common
At 20 degrees east longitude on the south side of the Arctic Circle, there is a group of remote islands floating lonely in the east of the Greenland Sea, cowering in the biting cold wind. This is the Spitsbergen Islands that no one pays attention to on weekdays. On August
Since the earliest dinosaurs appeared in the Moon Valley in Argentina 228 million years ago, they have rapidly evolved, developed and spread to every corner of the earth because they were very adapted to the ecological environment at that time. In the early Jurassic Period, which lasted from
As a large animal family, dinosaurs have ruled the world for more than 100 million years. However, as far as the dinosaur family is concerned, not all different species co-existed. Some species only appeared in the Triassic, some only lived in the Jurassic, and some species only appeared in t
1. Fossils are the wealth of all mankindFossils are the remains, relics and relics of ancient life preserved in rocks after a long period of geological action. Paleontological fossils are precious records and wealth left to us by life in different periods of billions of years of Eart
Q1: In what era did pterosaurs live? A: Pterosaurs originated in the Late Triassic about 220 million years ago and became extinct at the end of the Cretaceous 65 million years ago. They successfully survived on Earth for 150 million years and flew into the sky about 70 million years ea
大约在距今2.3亿年前的三叠纪，恐龙首次出现在地球上。三叠纪末的大绝灭使恐龙逐渐成为生物界的主导。但这个主宰地球1.6亿年之久的庞大动物类群却在距今约6500万年前的白垩纪-第三纪交界时期突然覆灭了。为什么正处于极度繁盛状态的恐龙会在很短的时间里灭绝？好奇心促使中外学者做了大量的研究。科学家发现，在白垩
Through the research of archaeologists, we can know that dinosaurs lived in the Triassic, Jurassic and Cretaceous periods. These three periods added up to a total of about 160 million years, which means that dinosaurs once ruled the earth for 160 million years. Hundreds of millions of years a
The asteroid hit the earth and wiped out the dinosaurs and destroyed most species on the earth, but mammals survived this catastrophe. So how did these small and fragile creatures, including our mammalian ancestors, survive this apocalypse? This is the most tragic day in
A latest British natural science research found that the reason why modern snakes can successfully survive and reproduce around the world must be thanks to the meteorite, an alien object that hit the earth 66 million years ago and exterminated most species, including dinosaurs. Scientists say
