Geodiversification: The Evolution of Geodiversity Through Time

Abstract Geodiversity has gained significant attention in the last three decades due to various research endeavouring to bridge the gap between geo- and biodiversity. This paper points at yet another parallel between the two disciplines: just as biodiversity expansion (i.e. biodiversification) can be evaluated through time, geodiversity change can also be observed on a timescale and referred to as ‘geodiversification’. The paper firstly reviews the biodiversification definition and some of its major events including the Cambrian explosion and Great Ordovician Biodiversification Event (GOBE) and suggests that being palaeontological, these can also be regarded as geodiversification events. In relation to that, the paper defines geodiversification and provides examples of important geodiversification events in the Earth’s history and some local-scale examples. The results show that major biodiversification events can occur due to the evolution of geodiversity.
