Abstract

Collenia is a name for calcareous structures in rocks of Upper Proterozoic (Algonkian) time and of world-wide distribution. It is described as the calcareous secretion of primitive microscopical algae, which themselves are never preserved. A number of similar forms are described under various names, and for brevity, they are all commonly referred to as "Cryptozoon" or "Stromatoliths", or even as "calcareous algae". [Previous studies, and recurrent opinions and interpretations of the subject are summarised and discussed. Conditions for the extensive development and thickness of the reefs are outlined. Recommendations for further study are given.]
