| biocenosis | A group of organisms in a self-sufficient community naturally occupying a small area with a uniform environment throughout. In the field of paleontology, it is one of three types of fossil communities, which depends on the condition and completeness of the community when found. Biocenosis is the most complete type, able to offer the most information about what the community was like when it was alive. (09 Oct 1997) |
