Rocks and the Rise of Ordovician Life

This is a collaborative project that aims to better understand the dynamics of biodiversification during the Early Palaeozoic (a time span ranging between -500 and -470 million years ago).

About the project

For the past 25 years, major evolutionary events such as the ‘Cambrian Explosion’ and the ‘Great Ordovician Biodiversification Event’ have been investigated through various research projects and regarded as distinct evolutionary events. However, the data used was strongly biased towards a limited number of geographic areas (Europe, North America). The present research aims, through a multidisciplinary approach and by bringing together an array of international specialists, to question this hypothesis by investigating and filling the numerous knowledge gaps related to the various aspects of the Ordovician biodiversification.

We also strive to encourage participation of ‘emerging’ countries through enhanced collaboration, field work, educational and outreach programmes together with workshops.

To date 192 scientists representing 42 countries are participating to our project.
