Great Ordovician Biodiversification Event (IGCP Project 410)

One of several recent and ongoing IGCP (International Geological Correlation Programme) projects concerned with biological diversity issues over geological time.

The overall aim of this globally based project is to appraise all known records of preserved biotas in Ordovician rocks, as a basis for a comprehensive evaluation of the manner in which the greatest diversification of marine life on Earth took place (about 450 million years ago). As part of the data collection process, a web-based relational database has been established for the input of biotal data (species level and above) as well as related geographical, stratigraphical and environmental information.
