    study, published in
    American Journal of Science and Technology, said the researchers were in a state of u.S. Cholesterol molecules were found in fossils of 5.8 billion-year-old organisms, confirming that the creature is one of the oldest known animals on Earth.
    , the oval, known as "Dickinsonia," is 1. 4 meters, the whole body has a rib-like structure, belonging to the Edikara biome, this kind of creature than 5. The large number of animals that appeared in the Camance outbreak 400 million years ago was nearly 20 million years ago.
    team at the Australian National University found the intact fossil on a remote cliff near the White Sea in northwest Russia, and analysis found that its tissues contained cholesterol molecules, one of the characteristics of animals.
    researchers say this proves that the animal population was large and abundant, earlier than previously estimated. Previous hypotheses suggest that arthropods are at 5. The Camance "suddenly" appeared 400 million years ago, but some researchers have speculated that arthropods should have begun to evolve slowly before the Camsoon, only because fossils from that period were difficult to preserve that no definitive evidence was found.
    The Dickinsonian fossil is a key to understanding how a bacterial-dominated world evolved into a large animal world after the Cambic outbreak, Said Boblowski.
    the Edikara biome was first discovered in the 1940s in the Edikara region of southern Australia. They are multicellular invertebrates living in the pre-Camphan oceans and are seen as a prelude to the Cammass outbreak that began with complex biodiversity. (Source: Xinhua News Agency Zhou Zhou)
