But recently, paleontologists have had to change this view and push the herbivorous history of dinosaurs to the early Cretaceous period, 125 million years ago, grasses began to appear. This was discovered during the study of fossils of the dinosaur Equijubus found in China. Mount Mazong is located at the northern end of the Hexi Corridor, in present-day Gansu Province, China. The mountain is named because it looks like a horse’s mane blowing in the wind. Mazong Mountain is a desolate place, but beneath that gravel are the remains of creatures that died hundreds of millions of years ago. In 2000, paleontologists from China and the United States formed a joint expedition to unearth paleontological fossils in the Mazong mountain area. During this excavation, paleontologists discovered a large number of fossils. Chinese paleontologist You – Hailu studied the fossils of a new dinosaur species and he named this dinosaur Equijubus. The genus name is derived from the Latin words “equus” meaning “horse” and “juba” meaning “mane”, the genus name meaning “horse mane” because the fossil was found in Mount Mazong. The new species was given the full name Equijubus normani, with “Normani” being named in honor of the famous British paleontologist David B. Norman. Illustration. Equijubus can be considered an intermediate dinosaur between Iguanodon and Hasrosauridae. Equijubus has a fairly large body when compared to a “basic” Hasrosauridae, but they can still run on two legs after being chased by predators. Fossil specimens of this dinosaur include skulls, lower jaw bones, cervical vertebrae, dorsal vertebrae and other parts. Through fossil analysis, it can be seen that Equijubus belongs to the primitive Hadrosauridae, it already possesses some features of Hadrosauridae, but its skull also has obvious features of Iguanodon. Paleontologists surmise that the dinosaur Equijubus could be up to 7 m long, 2 m high and weigh 2.5 tons, almost the size of a small truck. Equijubus would have had a long head, a horn beak on the front of its mouth and flat teeth on the inside of its cheeks, allowing it to chew on hard plants. Equijubus also have a robust body, they often walk on all fours and run on two legs when fleeing predators. Although there are not many fossils of this species, the discovery of Equijubus has great significance for paleontology. As a very primitive Hadrosauridae, Equijubus has shown that the Hasrosauridae may have originated in Asia and that they evolved directly from Iguanodon. 14 years after the Equijubus species was named, paleontologists are once again studying their fossils using the latest technology. They found evidence of herbivorous dinosaurs actually eating grass in fossils! On December 21, 2017, You Hailu and other paleontologists published a research paper titled “Dinosaur-related cuticles and crystals from the Chinese Gramineae family of the Cretaceous Period” on National Science Journal of China. The paper mentioned that the microstructure of primitive herbaceous plants (herbs, rice) was silicified between the teeth of the dinosaur Equijubus. This suggests that herbaceous plants were originally the food of this dinosaur. In fact, to answer the question of whether or not herbivorous dinosaurs ate grass, we need to know that the grass family is a large family of plants with more than 650 genera. Rice, wheat, corn, millet, sorghum, etc… the plants that we cannot live without are all grasses, and many other plants that we can eat are also grasses. People have always doubted the existence of the grass family, and the time period of its appearance is also quite unclear. And in the past, scientists always thought that they appeared after dinosaurs. But through the discovery of secrets from the fossils of the dinosaur Equijubus, we have learned that grass appeared on Earth 125 million years ago. This means that on Earth, dinosaurs of that time also had herbivorous habits (literally eating grass). The earliest known seed-bearing plants can be traced back to the Middle Jurassic or earlier, 164 million years ago. It was discovered during the Boda Jurassic period in Inner Mongolia. Although this plant is only a few centimeters tall, it already has roots, stems, leaves, and fruits.

People then talked about strategizing against rats, setting extremely sophisticated traps, or fortifying houses against small but annoying enemies. Six months have passed, the number of rats has once again increased sharply, despite thousands of tons of rat poison used, not to mention a terrible flood that swept across the east coast of the country. Rats are no longer an enemy to be eradicated, they seem to have become annoying black fluffy clouds that move everywhere where people have to learn to live together, according to the report. Guardian . Nightmare The nightmare that Australia is experiencing is known as the “rat epidemic”, caused by huge populations of house mice. The house mouse was brought to Australia by Europeans in 1788. Since then, rat epidemics have occurred several times in Australia when conditions are favorable, with increasing frequency. This year, the situation became so serious that the New South Wales state government had to announce an emergency relief package of 50 million USD for people to fight the rat epidemic, including money for rat poison research, drug support. mouse and rat traps up to $1,000 per small business and $500 per household.

But for many people, the support is nothing compared to the damage the rats cause. “We were away for four weeks and had relatives check the house every day. There was a period of about four days when no one came to look, and in those four days, they were all over the house,” said Louise McCabe, resident in the town of Tallimba, said. When relatives were asked to open the door by McCabe, thousands of rats were inside. “They chewed up the new carpet, they ate the wooden floor. The oven they broke. They ate the insulation inside the dishwasher,” McCabe said. McCabe later discovered rats nesting inside pillows on lounge chairs, crawling into kitchen cabinets, destroying electrical circuits. Damages totaled up to $30,000. The climax was when the woman put the clothes soaked in rat urine into the washing machine. When she returned, she discovered a dead rat had swollen inside the glass. Meanwhile, a farmer named Ben Storer living in Walgett, said that 800 hectares of his sorghum has been destroyed by the herd, causing damage up to 200,000 USD. Rats attack every part of Storer’s farm, from the grain barn and the mill to the swimming pool’s filter pipe. At the height of the rat epidemic, thousands of dead rats were found every time Mr. Storer used a grinder to grind the grain he harvested. Baiting is the only measure that can be deployed on a large scale to control rat populations. As a result, in the worst-affected towns, the smell of urine and dead rats was overwhelming. Local residents described the smell of rotting rats as “unbearable”. “With poison, we can kill 100,000 rats a night. But the next morning, another 200,000 will come back,” Mr. Storer said. “No one understands the rat epidemic until they’ve experienced it. No one understands the extreme stench, vandalized furniture. Rats eat all the insulation in the air conditioning system, eat the wires on the roof, corrode parts of the circuit board,” said John Southon, principal of Trundle Central High School. Winter hope While local residents seem to have given up on the fight against rats, New South Wales authorities have stepped in. Experts say they have successfully developed a rat poison that can turn the tide of the current war. A new rat poison using a super toxic chemical called bromadiolone is being approved for emergency use by the New South Wales government. However, scientists warn the drug can be dangerous for native animals that eat the dead rat. Steven Henery, broaching expert with the Australian Agency for Science and Industrial Research, said the coming winter would be an opportunity for humans to put an end to the current rat epidemic. “My hope is that winter will slow down the birth rate of mice, and that only a very small number of mice will survive,” said Henery. One of the real concerns, Mr. Henery warned, is that the rat population has a high winter survival rate, and if the weather conditions are favorable the following spring, they will start to thrive again. Farmers burn fields after harvesting to destroy the rat’s food source. Photo: Guardian. “In August, farmers need to go out to their fields, look for signs of infestation. If they find any, then they will have to kill them before the breeding season. property arrives,” Mr. Henry said. Any human rat eradication strategy will only be able to reduce the rat population to a certain extent. Experts say that to be able to overcome the rat epidemic, humans will have to wait for the help of natural phenomena that are really terrible for mice. “The very large number of individuals interacting with each other increases the risk of disease transmission. When this phenomenon occurs at the same time they run out of food, they will fall ill and start eating each other, eating the animals. young. That’s when their whole growth system collapses,” said Mr. Henery. But until that day comes, people will have to keep setting traps, laying baits, and praying the weather will turn bitter cold. “I can only pray for freezing cold. That’s all I can do right now,” McCabe said.

An ancient tomb was found in an ordinary village, the contents have astounded archaeologists: A banquet table is still intact! In 1993, a resident in Zhangjiakou, Hebei accidentally discovered that there was water seepage on the ground, so he called the concerned person to investigate. Thanks to that, an ancient tomb was discovered. According to experts, these graves belong to a family of Zhang built in the Lieu dynasty, more than a thousand years ago. The entire passage of the tomb is more than 6 meters long, going down the path is the arched tower gate, on this tower gate there are many carved decorations, lifelike patterns. There are two doors underneath the gate, like the houses we see today. The expert opened the door to see two statues on either side, similar to the guard. If you continue forward, there will be another wooden door, which can be opened to enter the back room, where a lot of precious burial items are placed. What surprised the experts, however, was not how luxurious the funeral items were, but a dining table. Photos of the dining table found (Photo: Sohu) In the back room, there is a large round table with eating utensils and fruit and dishes. Although most foods have gone rancid after thousands of years, they can still be distinguished: There are grapes, chestnuts and other common dishes on the table. Because the owner of the tomb believes in Buddhism, the meal is vegetarian, without meat. Next to the table and chairs, seems to want to invite the owner to dine at any time. In addition, there is also a small granary for storing sorghum and grains. There was also a green bottle of water on the table, in which there was a little liquid and an orange-red color, when approaching one could smell a strong aroma, it was deduced that it must be the wine thousands of years ago. . Based on the grapes and wine found, it can be inferred that in the Lieu period, people already had grapes and could use it for wine making. According to the epitaph found in the tomb, it can be speculated that the owner is a Lieu family and has done a lot of good deeds throughout his life, so it is loved by everyone around him. His epitaph also states that by entering the tomb, everyone can sit down and drink a glass of wine, which shows that this person is open and friendly. Rarely, an ancient tomb thousands of years ago can still be kept as intact, it is of great significance for later research. According to Sohu
