According to foreign media reports, the U.S. and French scientists opened a 3 million years ago the ancient mystery of animal brains, they re-show this has turned into an ancient animal fossils brain 3D images of soft tissue, which is the first in the scientific community times.

This ancient beasts are the modern relatives of sharks, is now extinct. With X-ray computer axial tomography (CAT), France and the United States has become the scientists obtained Shark fossils relatives 3D brain images, after which they use called “synchrotron” atomic particle accelerator to carry out micro – imaging. It is learned that the brain is known as a “Iniopterygian” fish found in the skull. Shark and another Iniopterygian are a modern species – silver shark relatives. This ancient beast once active in the world’s oceans, they live in shallow waters and mud of many waters, body length up to 20 inches (50 cm). The imaging report published in “The United States National Academy of Sciences.”

Iniopterygian imaging of the brain of great significance because: fossils of soft tissue is very difficult to be preserved, including the kidney, including muscle and organ is not. It is learned that, Iniopterygian fossils are in the United States, Kansas, one sedimentary shale found, because the skull was not crushed, the fossil is very special. At the time millions of years, the pressure on animal carcasses at the soil layer or increasing the weight of rock, fossil will inevitably be compacted.

Study author, said, Iniopterygian brain size is 0.06 inches × 0.27 inches (1.5 mm × 7 mm), in order to know the evolution of fish provides an important clue. Its brain has a larger length and visual-related leaf, but with the auditory input relevant regional has been made simpler.

Report of the Joint author, American Museum of Natural History paleontologist said: “Prior to this, we never have had such an exciting discovery. We now know that the brain may be similar to ancient fossils in preserved, we can look for other brain saved. “
