Dinosaurs Weren’t Fading Before the Asteroid—We Just Suck at Finding Their Fossils

Diversity is one of the greatest questions of paleontologists with dinosaurs. It was these ancient creatures, when the fateful asteroid crashed from the sky, while these ancient creatures decreased? One group of land believes that they are probably not.

Indeed, the fossils from the last dinosaur period are rare, compared to the previous visitors, this seems to be able to explain the whole story of the fossil record. The point can be seen in Moot: a road or another, the dead and the dead and 66 million years die die from this mass. But there is a matter of a little hot key among paleontologists.

For decades, scientists have been accelerating between both the king of the rates of generations between dinosaurs and argued against the idea. Those who believe in dinosaurs have decreased claim These new species appeared less soon compared to previous periods. Presented some shortcomings evidence It was partly responsible for the emergence of a variable climate, which is partially responsible for other herbivores, which proves better to compare food for food. But those on the other side believe Their colleagues do not seem hard enough for the signs that they remain before they are before them, as in the end of which they are before the end of dinosaurs.

The last shot in the ongoing battle comes from the cooperation of scientists in the United States, England and China. Their argument, these fifty In the magazine in the existing biology, While the number of fossils filled with the last 9 million years of the last 9 million years of the dinosaur age, it is more geology and a variable planet, the dinosaurs are actually a sign in landing.

According to them, land scientists, the dinosaur fossils from North America from the last 18 million years of dinosaur, 84 to 66 million years ago. In particular, the dinosaurs belonging to the families of Ankylosaurida, Ceratopsaee, Hastrosauridae and Tyrannosauridae. Especially in North American fossils, because 50% of all the fossils made since this period were found in the Western internal basin (WIB), which divided the continent in the continent half of the continent. In the evolution of dinosaur, “Represent an unprecedented database for examples”, wrote the team.

After creating a map of North America, then it was seen in the grill, as it seems that geology, geography and climate. Then they used a very common mathematical formulas to investigate modern biodiversity to calculate each of each of these families living in different grids. The results showed that the population will remain enough stable over time.

To find an explanation for the discrepancy between these findings and fossil records, the areas where dinosaurs will be discovered are dramatically changed. Today, how many of these days are in these areas, because these days are how many days are these days, and how often paleontologists have worried about a certain area.

According to their estimate, dinosaurs did not decrease, but they were likely to find evidence.

“The likelihood of finding dinosaur fossils is decreasing, the likelihood of dinosaurs lived in these areas,” said Paleontology researcher in the research college London London statement. “This shows that we cannot show that we cannot get the fossil record in the face value.

Although the study is attractive, it is probably not a smoker weapon. If nothing else is, the dinosaur may point to new areas to explore the full scale of the history. In this paleontological fist, it should be fun to see what the next punch is.
