The remains of previously unknown species of sharks

Millions of years ago on our planet did not liveonly huge dinosaurs, but also many other animals. Among them were even sharks, the skeletons of which now and then are in the most different corners of the Earth. More recently, the bones of a megalodon, which is considered the most terrible shark in history, were found in Mexico. This was a pretty interesting find, but in 2010, researchers from the Illinois state were able to unearth shark bones that were about 91 million years old. After a dozen years, the bones of the ancient predator were able to be put together and it turned out that this species of sharks was completely unknown to science. Why is the new species of sharks so interesting for scientists?

According to NewsWise, ancient shark boneswere discovered in one of the agricultural areas of Tipton, located in the US state of Kansas. Researchers Kensh Simada and Michael Everhart managed to unearth 134 teeth, 64 vertebrae and 23 scales of the ancient inhabitant of the seas and oceans. Researchers initially suggested that they came across shark bones of the species Cretodus crassidens, but none of the teeth found matched those of this shark species. It was then that scientists realized that they were dealing with a completely new shark for science.

In the United States discovered a new species of sharks

A new species of sharks called Cretodushoughtonorum in honor of Keith and Deborah Houghton, who are the owners of the land on which the remains were discovered. They voluntarily donated the find to the science museum.

We believe that further cooperation betweenpaleontologists and landowners are important to improve our understanding of the geological history of Kansas and the Earth as a whole, the scientists shared.

Despite the absence of many other bones,scientists were able to learn a lot of interesting things about the ancient predator. For example, that the length of his body was an impressive 6.8 meters, and he was quite large already at birth - even then the length could be about 1.2 meters. It is also known that the shark was very slow. After studying the remains, scientists decided to include it in the Lamniformes group, which also includes modern white and tiger sharks.

Researchers are very interested in the fact thatalong with the bones of a previously unknown predator, the teeth of an ancient squalicorax shark were also found. They also managed to detect fragments of the fins of ancient gibonton-like fish that looked very similar to predators. According to scientists, the shark they found was mainly fed by small gibodonts and died after an attack by a large squalicorax.

According to scientists, the study of ancient species of sharksable to tell a lot about both the past and the future of our planet. In particular, researchers will be able to carefully examine what role they played in the past. Also, importantly, they can figure out what will happen to our planet if the sharks suddenly disappear.

To find out, scientists have to spenda lot of research. But they already know how our life will change with the complete disappearance of bees. You can read about how the absence of honey insects will cause the collapse of the coffee industry and the meat industry in our special material.
