The Echinoid Directory

The Echinoid Directory

A comprehensive site covering fossil and recent sea urchin diversity. To quote the site, "The primary purpose of the site is to provide a taxonomic resource for the scientific community in which the genera and higher taxa of echinoid can be simply and rapidly identified. There are currently over 350 pages of detailed information about echinoid taxa. Here no holds are barred and technical terms abound. A reasonable grasp of echinoid morphology is assumed and these pages will be of most use to professional scientists and advanced researchers. For each genus information is given about the type species, the key diagnostic characters, its stratigraphical and geographical distribution, species currently assigned with confidence (not by any means exhaustive), and remarks about recent scientific publications dealing with this taxon. Wherever possible high-quality images are provided of specimens in oral, aboral and lateral views."
