Fish traces are discovered

According to Reuters, scientists have found traces of Tiktaalik roseae fish, also known as 'walking fish' in northern Canada. They existed 375 million years ago, having unique characteristics in the skull.

This is the first time researchers have described the characteristics of the skull of a species that is considered to be an evolutionary period from fish to terrestrial amphibians.

Through research, scientists from the Philadelphia Institute of Natural Sciences (USA) said that underwater migration is a complex process that is not only the transition from fish fins to feet, but also their heads Also significantly transformed to be suitable for terrestrial habitats. They carry both fish and lungs.

However, most of the time they live in the water and are carnivores. They are about 2.5m long, sharp teeth and flat crocodile-like heads.
