| 摘 要： | Microtubular metazoan fossils with multibranches are found at least 4 times from the Sinian （Ediacarian） Doushantuo Formation at Weng＇an, Guizhou, China. Their living mode should be the benthonic colony with higher ability of asexual reproduction. The inner of the tube with cross-walls and chamber shows that these fossils are basal or stemgroup cnidarians, similar to extinct tabulates. The multi-branching microtubular fossils are real metazoan found from Weng＇an biota, which is very important for studying the origin and evolvement of metazoan.

| Abstract: | Microtubular metazoan fossils with multibranches are found at least 4 times from the Sinian (Ediacarian) Doushantuo Formation
at Weng’an, Guizhou, China. Their living mode should be the benthonic colony with higher ability of asexual reproduction.
The inner of the tube with cross-walls and chamber shows that these fossils are basal or stemgroup cnidarians, similar to
extinct tabulates. The multi-branching microtubular fossils are real metazoan found from Weng’an biota, which is very important
for studying the origin and evolvement of metazoan. |
