The Zhanghetherium fossil, which dates back about 120 million years ago, is the world's first entheodont fossil with a relatively complete skeleton and the first mammal fossil discovered in the Jehol Biota. The morphological characteristics of its cranium base and mandible indicate that the d
Megaraptor Erlian, which dates back about 80 million years ago, belongs to the oviraptorosaurs, a close relative of birds. It represents a transitional type of oviraptorosaurs and is also the largest maniraptorosaur discovered in the world (a group including oviraptorosaurs). A group of bird-
The primitive Jeholornis, which dates back to about 120 million years ago, is the most primitive bird discovered so far in my country. Its primitiveness is second only to the Archaeopteryx discovered in Germany, and it represents the oldest known specialized bird. Seed-eating birds. Its disco
The world's first pterosaur egg and embryo fossil was discovered in the Early Cretaceous Jehol Biota in western Liaoning, my country, about 121 million years ago. It is also one of the three pterosaur eggs that have been discovered in the world. Since the discovery of pterosaur fossils 220 ye
Turtle is the general name for marine turtles. There are 5 species of marine turtles living in our country's oceans (there are only 7 species in the world), mainly distributed in the Xisha Islands and the port of Huidong County, Guangdong Province, followed by the coastal areas on the outskir
As the earliest vertebrate with active flight capabilities, the macroevolution of pterosaurs has received widespread attention in the academic community. The evolutionary history of pterosaurs can be roughly divided into two stages, namely a 115 million year period of prosperity and a 65 mill
There is an animal whose existence is very short. You will definitely ask what is the meaning of their life? In fact, their only purpose of living is to reproduce. Although their lifespan is short, their existence can be traced back to 200 million years ago, which fully proves their adaptabil
There is an animal that has existed in the world for more than 500 million years and is also a magical animal that is immortal. When they are threatened, sick, or old, it will revert its cells to the polyp or puberty stage and then form a new one. Polyp colonies. Arguably creating a younger v
Look at this strange animal, it looks like a scoop. Do you know what kind of animal it is? Let me tell you! It is the famous horseshoe crab!The horseshoe crab is an animal that once lived in the same era as the dinosaurs. However, the huge dinosaurs did not escape the catastrophe at the end of the C
Arthropods are the largest category of animals, accounting for approximately 85% of the more than 1 million species of animals currently known. The body of this phylum is divided into three parts: head, thorax and abdomen, and the appendages are segmented, hence the name arthropods. Currently
The evolution of living things is not like modern humans climbing stairs, from the top of one staircase to another. It is a transition from the ancestral form of this group to another group. Birds evolved from an early branch of reptiles. The earliest bird fossil is the world-famous Archaeopt
Between 270 and 135 million years ago, the main place of biological evolution shifted from water to land. The fern forests on land were gradually replaced by gymnosperms represented by cycads, ginkgo, and metasequoia. The vast land is full of dense virgin forests. But at that time, there was
Scientists recently believed that the ugly herbivorous reptile called "bunostegos" was discovered to have evolved from 260 million years ago, and its fossils have now proven that this creature appeared earlier than the dinosaurs. "Bunostegos" are cow-like in appearance, with bulbous growths o
1. Dinosaurs also wooed by wagging their tails. Scientists came to this conclusion after studying small flightless dinosaurs, modern birds and reptiles. Oviraptorosaurs had strong, soft tails with colorful feathers that they could show off. "Such a tail is perfect for showing off t
Different eras require animals to have different survival abilities. If you lived in ancient times, huge size and ferocious habits once became the most important characteristics of animals. Currently, 593 species of birds, more than 400 species of animals, 209 species of amphibians and reptil
The end of the Cretaceous period witnessed one of the most dramatic mass extinctions in Earth's history. Find out what caused the extinction of dinosaurs and many other animals. The fossil record shows that during the first 175 million years of their existence, dinosaurs took on a variety of
Although dinosaurs lived millions of years ago, we know they existed because some of them became fossils after they died. How were dinosaur fossils formed? Below we explore this process in more detail. Skull fossil of the dinosaur Hypsilophodon, found in the UK
Dinosaurs were a group of reptiles that dominated land for more than 140 million years (more than 160 million years in some parts of the world). They evolved in different shapes and sizes, from the terrifying giant Spinosaurus to the chicken-sized Microraptor, and were able to survive in a va
