Fusil Fishs put a new light on the evolution of extra dental to eat hunting

Experts have revealed the initial known example of a deep dental fish inside his mouth. It is a 310 -year -old Jovasim ray fund fish that has developed a unique way to eat hunting.

Platosomes had a unique way of food that had never been seen since then-from that time to “cutting tongue”, a special set of teeth on the floor and helps to crush it and chew hard foods like shells or insects.

Today, most fish uses their jaw to cut and chew, but some also have tongue cutting, which acts like other jaw sets. So far, the oldest fish with such dental management lived about 150 million years later.

To publish their results The letters of biologyThe International Research Team used high resolution CT scanning to rebuild Fusil’s internal anatomy, which was discovered in the form of carbonifers rocks in the UK County of Staffaire. Researchers discovered a sophisticated arrangement of toothpaste on the roof of the fish and the roof of the flower skeleton.

“Our discovery helps us understand how the fish was developed after the widespread extinction, which eliminated many species, which eliminated many species,” said Professor Sam Galis, a lead author from Birmingham University.

“Different fish groups have been developed several times – which includes modern trouts and bonefishs such as modern, showing that this is a useful tool that helps fish to eat different types of food and survives in different environments.”

The language cutting method involves opposing dental sets.

The studied platesomas are uniquely stored in 3D, which allows researchers to look inside their mouths and digitally separate its anatomy. This shows a multi -part lower tooth plate and tight upper plate, both have the same layer of nails.

Dr. Matthew Kolman, co -author of the University of Louis Will, commented, “Like a fish -like bobstrania group, there was more cutting of tongue cutting and they did not use their jaws at all, relied on their language cutting to crush their tongue.

This discovery supports a model of rapid innovation in the early -ray fish, after which after the massive dedication of the closing Dunnan, the ray has been tested with new strategies for fish -related fish.

Professor Matt Freedman, co -author of Michigan University, commented, “One of the many food feeding is that emerged during the time. This fish represents an important evolutionary move and helps us understand how the ancient environment works.”
