CALIFORNIA – prehistoric sharks found for the extinct species that are the ancestors of these aquatic animals. Prehistoric sharks lived in the period of Devon when the Quartets began to dominate the evolutionary process.

The director of the Sharks Research Program in Florida, Gavin Naylor, shared wonderful video gray sharks or sharks with combs, which are scientifically known by the Latin name Hexanchus griseus

This is not the first time that scientists have come to know animals that they thought were extinct before they found turtles on the Galapagos Islands, believed to be extinct. Wonderful, because they found it again 110 years after losing it.

Without a doubt and undoubtedly, nature is one of the greatest secrets surrounding our world, and it is always a new secret every day waiting to be solved.

Previously, researchers suspected that the shark had a jaw-free jaw. However, a recent analysis showed that he had teeth.

Michael Coates, a professor at the Department of Organic Biology and Anatomy at the University of Chicago, the chief researcher of the study, said that the shark is not similar to other shark fossils that were discovered. This prehistoric shark was found with bones that are still in place.

Scientists examine the prehistoric shark, the only one found in the Devonian period to determine that sharks and human ancestors split off during the silhouette about 440 million years ago.

Fossil also revealed a lot of information about the evolutionary history of sharks. "Fossil has revealed new information about the diversity of previous sharks, to which we have not yet had access," Coates said.

However, this new information makes researchers difficult to understand shark breeds. Research shows that the development of sharks has more branches than previously known, some of which are united. This has led to the development of the characteristics of modern sharks, such as double gills and long throats.

The new findings of the research were published in the Book of Royal Society B. This was reported by the International Business Times.
