| Summary: | Origin and growth pattern of some of the elements of the oldest Ediacaran assemblage of Mistaken Point, most crucial to deciding their biological affinity, have been discussed. The fauna of Newfoundland marks the beginning from small globular bodies like strings of beads. The bead-like globular bodies had a tendency to align themselves as chains, double chains and radiating forms producing spindle-shaped organisms. The globular bodies thus represent a link between pre-Ediacaran and Ediacaran life forms. Some of the globular bodies formed concentric aggregates or developed tendency to split in to several parts to initiate the development of lobate structures (Ivesia or Ivesheadia). Isolated beads or globules germinated to stalk that evolved to frond-like forms. |
