    Xinhua News Agency, Nanjing, August 6 (Reporter Wang Wei ) reporter 6 from the
    Nanjing Institute of Geology and Paleontology was informed that a chinese, Estonian, American palaeontologists composed of a research team, the latest living in about 400 million years ago paleontology - butyres, confirmed the "identity."
    butyres are tiny creatures that lived in ancient oceans. They existed between 485 million and 359 million years ago and are typically between 50 microns and 2 mm long, mostly bottle-shaped, jug-shaped, cylinder-shaped, and look a lot like miniature versions of drifting bottles. Don't look at the small, long-extinct buttworm, but it is a "star species" in paleontical research. In ancient oceans, the number of butyres is numerous, widely distributed, and they evolve rapidly, different forms of butyres have their own corresponding age of existence, paleontologists often use this as a criterion to judge geological periods.
    , however, since it was officially discovered in 1931, it has been a mystery what a few butyflies are. It was once thought that it was a class of extinct native organisms. In recent years, a growing number of scholars have tended to believe that butocytosis is the egg or sac of a certain type of later animal.
    , the team systematically sorted through more than 370 400 million-year-old butythrough fossils to solve the mystery. The 370-species fossils cover all known genus cloths. Morphological analysis shows that even the fossils of the same species of butylains differ several times in morphological length, which is very different from the similar characteristics of the same species of animal eggs. A comparative study of 45 kinds of invertebrate eggs from modern aquatic 6-door 10-frame showed that the difference in size of the cartillas was significantly larger than that of modern aquatic invertebrate eggs. This suggests that butine is not the egg of an animal, but is more likely to be a separate protozoan.
    " makes it clear that the butytosis is an independent organism, meaning that it has its own unique development and evolution process. Especially for this iconic species, to understand its development, human understanding of the earth, understanding the origin and evolution of life are of great significance. Liang Yan, an associate
    nangu Institute in charge of the study, said.
    research was published recently in the authoritative journal Biology, the Proceedings of the Royal Society, Series B Biological Sciences.
