The Royal Ontario Museum (ROM) in Toronto has announced the discovery of fossils belonging to a strange 3-eyed predator whose brain has been preserved inside fossils for 506 million years.
Biologists have found fossils in the Bridge Shale, a formation in the Canadian Rockies of British Columbia, located within the Yoho and Coutinho National Parks.
The study’s results were published on Saturday, July 9, 2022, in Current Biology by Josef Moseyuk, the lead author of this study, which has become a real trail discovery in the fossil results.
Strange 3-eyed predator discovered by researchers
The researchers found a marine predator named Stanlicaris hirpex, a 20 cm long animal. This creature had teeth, claws, a split body with floating flaps around it, and bulging eyes. This creature, which must have been a nightmare for tiny creatures on the ocean floor, belonged to an extinct group of arthropods.
Stanley Kars’ brain survived 500 million years later.
Researchers in Canada have discovered that fossils are so well-preserved that the predator’s brain and nerves were visible.
The study’s lead author described the fossils as a “remarkable find”, adding: “What makes this discovery so remarkable is that we have brain remains and other elements of the nervous system. There are dozens of templates that show, And they’re incredibly well-protected and show really great detail.
“The details are really crisp and beautiful,” concluded Musuk, who is pursuing a PhD in environmental and evolutionary biology at the University of Toronto, Canada.
In fact, 84 fossils show what Stanley Kars’ brain and nerves were like. It can be seen from the microscope that the brain is made up of two parts.
The modern arthropod brain consists of three parts, which explain how organisms evolved over 506 million years. The brain structure of the ancient creature was also associated with different parts of its body, which in fact has proved to be different from this research.
