In Canada, found an alleged imprint of the most ancient multicellular one. Article Paleontologist Elizabeth Turner (Elizabeth Turner) with a description of the find is published in Nature magazine.
Turner studied the breed of the Nerterozoic era, formed a few hundred million years before the beginning of one of the first glacial periods in the history of the Earth. There, she noticed unusual branched imprints consisting of a plurality of tubular structures from a length of a millimeter to several centimeters. According to the paleontologist, the fossil is the remnants of ancient sponges with a protein skeleton.
The age of findings is about 890 million years. This suggests that a multicellular life appeared for 350 million years before the Cambrian explosion – the sudden appearance of various forms of complex living organisms of 550 million years ago. If data on the origin of prints is confirmed, this will be the first physical evidence that multicellular appeared long before an increase in oxygen concentration in ocean waters.
Previously, scientists of the University of Missouri in the United States found in the Nevada State Desert Petrified Digestive Tract 550 Million Years.
