Every year scientists make important sensational discoveries that contradict everything they write in history textbooks and radically change the idea of the Earth.
We have collected 9 of the most incredible finds that will make you reconsider everything we knew before.
1. Prehistoric people lived with dinosaurs
In 2012, in Dawson County, Montana, paleontologist Otis Kline Jr. discovered the frontal horn of a herbivorous Triceratops during another excavation. During the study of the horn, scientists made an amazing discovery: the age of the dinosaur is about 33.5 thousand years. This statement disputes the opinion that reptiles became extinct more than 65 million years ago, and therefore it is possible that prehistoric people lived on Earth with dinosaurs.
2. Antarctica was a tropical continent

Today, 98% of Antarctica is covered with a layer of ice, but millions of years ago this continent was considered tropical.
Exploring the territory of Antarctica, scientists found the fossilized remains of thermophilic plants: African baobabs and ferns, as well as ichthyosaurs - ancient reptiles that previously lived in warm areas.
An amazing discovery led the researchers to conclude that more than 50 million years ago, palm trees grew on the coast of the coldest point on earth, and the water in the ocean was warm.
3. The Romans discovered North and South America
There are suggestions that the Romans visited mainland America much earlier than Columbus. This is evidenced by a ceramic head figurine discovered in 1933 under the floor of an ancient building in Mexico, which differs from the samples of local art, but resembles Roman sculptures that were created in the 2nd century. Moreover, in the waters of Guanabara Bay in Rio de Janeiro, researchers discovered artifacts belonging to Roman culture and dating back to the 3rd century. Therefore, one of the theories of scientists claims that the Romans were the discoverers of the continent.
4. Stone balls of Costa Rica
Another mystery that researchers are racking their brains over are stone balls found in Costa Rica. They are perfectly regular round in shape and are made from different rocks: limestone, sandstone and igneous rock. Their weight reaches 16 tons.
It is known that many stones formed various shapes: triangles, lines, and even astronomical configurations. But the direct purpose of the balls, which were left to us by ancient civilizations, still remains unknown.
5. The pyramids were built not only in Egypt?
We all know that the Egyptian pyramids are the most grandiose and unique structures on Earth. However, in 2005, an amateur archaeologist Semir Osmanagic made a sensational statement: in Bosnia, pyramids are much older and more Egyptian. World scientists took such news extremely skeptically and even provided information that Mount Visochitsa, which the researcher took for a pyramid, is a natural formation, not a man-made structure.
Osmanagich himself is categorically against such skepticism. Who knows, maybe someday the researcher will be able to find evidence of his case.
6. Precious bars from Atlantis
Historians are still actively debating the real existence of Atlantis. But recently a discovery was made that forced to reconsider the point of view of all skeptical scientists.
During another dive into the waters of the Sicilian Jela, amateur diver Franco Cassarino discovered an amazing find - 39 ingots of unknown origin, which had lain under the wreckage of a sunken ship for 2.5 thousand years. The examination showed that the metal from which the ingots were made is orichalcum - an alloy of several rocks. Archaeologists argue that the results of the analysis prove the existence of a once prosperous state, because even Plato in his texts mentions orichalcum as a metal popular in Atlantis.
7. The first to visit the territory of the current USA were the Chinese
In several states of North America, scientists have found thousands of rock carvings, some of which have been identified as ancient Chinese writing.
Researchers concluded that Asians entered the northern part of the current United States around 1300 BC - much earlier than both Columbus and the Romans.
8. Life on Mars
Around the question "Is there life on Mars?" there were always heated discussions. But not so long ago, a discovery was made that will help scientists come to a common answer.
Researchers have found that in the past, the Red Planet was covered by a huge ocean. The data they received from artificial satellites and rovers indicate that Mars was once much warmer than today, and part of its surface was covered with liquid water. This find makes it possible to safely assume that Mars was once a truly inhabited planet.
