What was the ancestor of the crocodile and what was the crocodile called in ancient times

The ancestor of the crocodile. Measuring between meters and weighing about 40 kilograms, this animal has a robust body with a long beak that bears a striking resemblance to a large dog.

It seems that the study of the ancestors of crocodiles is not clear now.

However, it should be contemporaneous with the dinosaurs.

Brazilian paleontologists recently announced that they have discovered the fossils of a new predatory species, which is the ancestor of today's crocodiles. This discovery fills a gap in the evolutionary history of crocodiles.

Has mammalian characteristics.

The fossilized skeleton was discovered in 2004 and is so well preserved that paleontologists named it "Montealtosuchus arrudacamposi". This animal is between meters and meters long, weighs about 40 kilograms, lived between 100 million and 100 million years ago, in the late Cretaceous period, and lived mainly in the Paolo Otto region of present-day São Paulo, Brazil.

Although this new species is not genetically directly related to mammals, it has distinct mammalian characteristics. According to fossil speculation, it has a robust body with a long mouth that bears a striking resemblance to a large dog, matching the characteristics of a mammal.

Fills a gap in the evolutionary history of crocodiles.

Professor Philip, a paleontologist at the United University of Rio de Janeiro in Brazil, after studying fossils, believes that this creature is a creature that is between prehistoric crocodiles and modern crocodiles. The Ancient Crocodile is a very agile one.

The ancestor of the crocodile is the Prusch crocodile.

The ancestor of the crocodile was a giant crocodile called the Pruss crocodile.

Terrestrial primordial dragons.

Crocodile of Prus.

The ancestor of crocodiles is a reptile of the crocodile class. This crocodile reptile lived in the Triassic period, looks more like a lizard, has a body length of only 50 centimeters, and its hind limbs are extremely slender, mainly using bipedal walking, mostly feeding on insects, invertebrates, etc. Of course, crocodiles are not just the ancestors of crocodiles, they are older than the dinosaurs, and contain more evolutionary clades than the modern crocodile branches, such as the ground lizard crocodile, the jumping crocodile and the lion-nosed crocodile, which contain almost all species that are closely related to the modern crocodile.

Moreover, crocodiles are subdivided into protocrocodiles, mesocrocodiles, sea crocodiles, and true crocodiles, which also means that crocodiles begin to evolve towards a variety of environments.

Through human research on crocodile teeth, the evolution of the diverse diet of crocodile ancestors was summarized by measuring the structure and shape of the teeth. It is thought that the earliest crocodiles were probably herbivorous, but after the mass extinction of the Triassic period, the diet of the crocodile ancestors began to gradually evolve to carnivorous or omnivorous, and the herbivorous branch appeared only three times, and the length of the mouth became more flattened, wide and slender, and the teeth at the front of the jaw became longer and longer.

The ancestor of the crocodile was the crocodile. The crocodile is a carnivorous oviparous vertebrate reptile that is the oldest reptile of the same age as the dinosaurs more than 200 million years ago, and one of the most primitive animals that have survived to date. Crocodiles survive and thrive because of their strong vitality, becoming one of the oldest living "living fossils" on Earth.

The crocodile is an endangered wildlife and is internationally listed as an endangered wild animal and plant under Class I protection.

Protection levelChinese alligator, Central American alligator, South American alligator, narrownose alligator, barramundi, intermediate crocodile, Philippine crocodile, Petén crocodile, Nile crocodile, Ganges crocodile, bay crocodile, diamond crocodile, Siamese crocodile, alligator, Malayan crocodile, fish-eating crocodile, etc. are endangered species of wild animals and plants, which are internationally important protected species, and are listed in Appendix I by the CITES (International Convention on Endangered Species of Wild Fauna and Flora) of the Washington Convention, which is prohibited from being international.

In addition, all species of the reptilian crocodile are listed on the CITES Appendix II list, which is regulated internationally**.

The ancients called the crocodile, generally called the "dragon" pig dragon or earth dragon, which is what we call the crocodile.

The ancients depicted crocodiles:

According to the Naturalist Chronicles, "there is a crocodile in the South China Sea, which resembles a turtle (tuó)" Modern research believes that the animal of Qingxiao is the Yangtze crocodile, and it is also called the "pig dragon" by the ancients. It should be noted that the character "鼍" also exists in the oracle bone inscription, which is an animal with a shell on its back and four legs and two eyes. This further suggests that the crocodile shaped like a dragon is not a dragon.

According to the Ridge Table, the crocodile has four legs, a long tail, and is shaped like a ray, and its movements are agile. It has sharp teeth like saws in its mouth and often eats people. There are many deer in the mountains of Jiangnan, and they are most afraid of crocodiles.

If the deer walks on a cliff near the river, the crocodiles howl incessantly, and the fawn falls off the cliff in terror and will be eaten by crocodiles in the water.

It is recorded in the book that Li Deyu, the Taiwei of the Tang Dynasty, was demoted to Chaozhou, and his boat broke down when passing by Crocodile Beach, and the treasures, antiques, ancient books and paintings collected in his life fell into the water. He let Kunlun Nu, who accompanied the ship's reply, go into the water to fish, but found that there were so many crocodiles in the water that no one dared to go into the water, and it was rumored that this was where the crocodile's nest was.

According to the Chronicles of Foreign Objects on the Ridge Surface, Wang Juzhi, the governor of Chaozhou, once caught a crocodile, the size of a small boat. It resembles a ray, its mouth is about the length of its body, and its teeth are as terrifying as its serrations. There are two colors, yellow and green, as well as white.

The crocodile's tail has three hooks, which are very sharp, and when encountering deer, wild boar, etc., it is taken by attacking the hook with its tail.

According to the book, the local people are good at hunting crocodiles, usually tying dogs and pigs to bamboo rafts, covered with iron hooks, so that the bamboo rafts drift with the water, and after the crocodiles find out, they come to the raft to hunt pigs and dogs, and are injured by iron hooks, and then people take the opportunity to kill them and take them out of the water to cook. <>
