Where did dinosaurs live?

The best way to study what animals lived on Earth millions of years ago is through fossils. Fossils are the remains of plants and animals immured in rocks. These petrified remains can be shells, insects, leaves, bones, whole skeletons, or simply footprints left by prehistoric animals on the banks of swamps.

According to this evidence, scientists have concluded that dinosaurs inhabited the Earth about 180 years ago, and died out about 000 years ago.

Which of the fossils found led scientists to this conclusion? The most common are bones, teeth and claws. Based on these fragments, skeletons are reconstructed, making it possible to judge the structure of the body. Nests and giant bones of dinosaurs have been found in the Asian Gobi desert. Scientists managed to find a fossilized dinosaur egg, shaped like a potato, from which the dinosaur "chicken" almost hatched. Dinosaur fossils have been found on every continent.

From this we can conclude that dinosaurs inhabited all parts of the world millions of years ago. However, certain conditions were necessary for the existence of dinosaurs. Dinosaurs were reptiles, that is, their body temperature changed in accordance with the temperature of the surrounding air. Many of them lived in places where lush vegetation provided them with food.

But about 60 million years ago, the Earth's climate underwent a huge change. The swamps have dried up. The plains turned into mountains. The climate became colder and drier. So the dinosaurs not only lost their habitats - swamps and plains - but also became lethargic due to the cold snap. The cold also destroyed a significant part of the vegetation that served them as food.

Over time, dinosaurs, unable to adapt to new conditions, became extinct. In their place came warm-blooded animals with a larger brain, with the ability to adapt to new, changing conditions.

Random interesting fact from the Great Encyclopedia:

When was the first sculpture created?

Sculpture is probably the oldest art. People carved stone even before they started painting or even building houses. Only a small number of objects have survived, illustrating what sculpture was like thousands of years ago. But people living today at a primitive stage of development often carve objects from stone that can give an idea of \uXNUMXb\uXNUMXbprehistoric sculpture.

Prehistoric sculpture was not supposed to be beautiful. It has always been intended to be used in rituals. The figures of men, women and animals were made in honor of the forces of nature, which were worshiped as evil or good spirits. Early civilizations also used sculpture to express their beliefs.

The ancient Egyptians believed in life after death, and they carved life-size or larger statues of their rulers, nobility and gods out of stone. Statues were placed in graves, and the Egyptians believed that the spirit of the deceased person would return to it. One of the greatest periods in the history of sculpture came with the advent of the Greek civilization - around 600 BC. e.

For the Greeks, sculpture became one of the most important forms of expression. The Greeks made the image of the human figure the main object of their art. Greek sculpture was always looking for the best ways to depict the human figure.

During the first millennium of Christianity, very few sculptures were created. But over the next three centuries, some of the most impressive Christian churches were built, and a large number of sculptures were created to decorate these churches. Later, during the Renaissance, the human figure was exalted again, and the great sculptors created masterpieces that constitute the treasury of world culture.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

GPS alternative works even underground 26.06.2023

Researchers from Japan propose a new alternative to the global positioning system (GPS), which will significantly improve the accuracy and expand the ability to navigate even in conditions where being in open space is impossible. Their idea is to use muons - particles that occur when the sun's rays interact with the Earth's atmosphere. Muons are able to penetrate any solid surface, which means that navigational equipment will function without the need to communicate with satellites in open space.

The most surprising thing about this concept of Japanese scientists is that the muon-based wireless navigation system allows you to determine objects even underground and in water. The basic principle of MuWNS (from the English. Muon Wireless Navigation System) is to continuously track the "signals" from muons, which form a continuous "rain" of particles. Every square meter of the Earth's surface is exposed to approximately 10 muons every minute.

Using special sensors, scientists managed to achieve high accuracy even in houses with basements - from 2 to 25 meters, depending on the depth and speed of human movement.

Although the practical application of such technologies is still in the distant future, researchers are already working to remove some of the limitations. They plan to improve the accuracy of the system by using atomic clocks, although these are currently too expensive for widespread use.

Another problem is the inability to capture the movement of objects in real time, so scientists need to develop methods to display and record the movement of objects or people in real time.

However, scientists believe that in the future this technology will be able to significantly enhance the functionality of GPS in areas where it is currently limited.
