Scientists were wrong about the appearance of one of the first animals on Earth

From the moment when scientists discovered the fossils of one of the most ancient animals on Earth, has already passed more than half a century. Creatures whose fossilized footprints were found, was called dickinsonia and dwelt at water depths of about 558 million years ago. What species of animal they are, scientists are still unknown: perhaps they are the ancestors of jellyfish, worms, or even mushrooms. All this time scientists were sure that the ribbed prints — this is the traces of their bodies, but researchers from the Australian national University believe that their bodies had a more complex structure.

According to a team of scientists under the leadership of biogeochemical Ilya Bobrovsky, the famous casts of ancient animals can be simply copies of their skeleton, or hard tissue of the inner part of the body or back. This assumption opens the scientists more questions and features, such as ancient sea creatures could have mouth, stomach, and other organs that are inherent in sovremennitsy.

Based on this, scientists suggest that even if in dickinsonia species was not of the skeleton, different density tissue precisely was the place to be. Perhaps this is what the prints of ancient animals so well preserved, researchers have long been unable to find this explanation.

That dickinsonia are the most ancient animals in the world, the researchers guessed a few years ago. Then Bobrovsky and his team were studying the molecules inside the fossilized remains and found they cholesterol. This fat is a direct proof that dickinsonia — the earliest ancestors of modern animals.
