The first animal to fly on Earth was an ancient insect called Rhyniognatha hirsti 400 million years ago. The oldest insect fossil was discovered in the famous Rhynie Flint Formation (Scotland, Early Devonian Period of the Paleozoic Era, 396-407 million years ago): a wingless endognathous insect Rhyn
Humans are the new generation of "Earth Overlords" after the dinosaurs, but the two appeared 58 million years apart. This is a long process, and many stories must have happened during this period. After the dinosaurs became extinct, what happened to the earth again? What did you experience? H
The earliest hypothesis about dinosaur mating positions was proposed by a scholar named Halstead in 1975. However, due to his understanding at the time, he believed that dinosaurs, like birds, did not have penises and adopted cloacal kissing. He proposed that the male dinosaur would wrap its
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 word dinosaur (Dinosaur) comes from Greek, which means "terrible lizard" (in the mid-19th century, British scholars named it after the Greek dino (terrible) and saur (lizard)). Because of this, people are convinced that dinosaurs are huge and terrifying animals. When people first discover
Cockroaches, also known as cockroaches, sweet lady, slippery bugs... are all kinds of insects in various shapes and forms, and their official name is cockroaches. This is a global insect that is widely distributed in the five continents and four oceans of the world, and is especially prolifi
1. Why do hermit crabs live in other people's homes?Because hermit crabs do not have hard shells and their abdomens are soft and curled, they are extremely vulnerable to harm from other animals. Therefore, hermit crabs can only live in the empty shells left by some dead snails to protect their s
I'm sitting in Jakob Vinther's office, trying to find the right words to formulate the question I want to pose: Did Tyrannosaurus rex have a - and that's a shameful word - penis? "So I have to..." I stammered, getting more and more panicked. "...You have to mate," Professor Winsor responded l
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
The latest research claims that the dinosaurs became extinct after a meteorite hit the earth 65 million years ago in the late Cretaceous period entirely due to "bad luck." New research believes that if the meteorite impact on the earth in the late Cretaceous period had been earlier or delayed
About 66 million years ago, the dinosaurs, which once ruled the earth for 200 million years, suddenly became extinct; the current authoritative explanation is that an extraterrestrial asteroid hit the earth, causing dust to cover the sky and acid rain to cover the earth, cutting off the food
Research led by China's Capital Normal University found that the Mireosaurus, which lived 150 million years ago, had teeth when it hatched. Researchers said in a report published in the professional journal "Current Biology" that as the young dragons grew, they may have switched from carnivor
It can be said that humans are quite familiar with dinosaurs. Whether it is the dinosaur skeleton fossils at the Natural History Museum in London, the dinosaur world in Hollywood science fiction films, or the detailed introductions in school textbooks, from the age of dinosaurs to the extinct
Scientists say they now have clear support for the theory that an asteroid struck the Earth and wiped out the dinosaurs. The cause of the extinction of the dinosaurs and most of the animal species on Earth has long been debated in the scientific community. Some scientists believe that an aste
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
It was a disaster we could hardly imagine. 66 million years ago, an asteroid with a diameter of 15 kilometers hit the earth. Its power was equivalent to 10 billion Hiroshima nuclear bombs. The radioactive fireball reduced everything within hundreds of miles to scorched earth, and the impact c
For more than a century, people believed that dinosaurs were just brutal animals that didn't take care of their offspring. But starting in the 1970s and 1980s, archaeological discoveries revealed that dinosaurs also had more complex social behaviors. Maiasaura is a plant-eating dinosaur that
