The pages on biogeography of the Vendian were written by Ben Waggoner to accompany an article submitted to the journal Terra Nova. The most recent update to these pages was made on June 18, 1997. Updates after this date will be made as appended Web pages, not alterations to the existing pages (except in the case of typographical errors); this is to promote stability of these Web documents and increase their usefulness as resources.

There seems to be no consensus at this writing on how to cite WWW documents in the scientific literature. If it is deemed desirable to cite these WWW pages specifically in a scientific paper, apart from the manuscript to which they are connected, a possible citation style might be:

Waggoner, B. M. 1996. Biogeography of the Late Precambrian "Ediacara biota." https://ucmp.berkeley.edu/vendian/biogeo.html. Last updated November 2, 1996.

However, since the status of Web publishing is still not resolved, it may be more acceptable to cite these pages simply as "Waggoner, unpublished results" or "unpublished data."
