中文释义

英文释义

名词 n.
  1. Any organism of the clade Rangeomorpha, Precambrian (Ediacaran) sessile organisms resembling ferns, possibly descended from sponges and among the oldest known complex lifeforms.
    — Previous comparisons of rangeomorphs with cnidarians or ctenophores now seem unlikely. The fact that both sides of the rangeomorph structure are essentially identical, is not consistent with the rangeomorph frondlet "representing the bases of an array of open tubes that housed polyps or other filter feeding organisms."
