Reefs of Time: What Fossils Reveal About Coral Survival

23 February 2026

Reefs of Time is a joy to read, crafting together scientific methodology and tales of fieldwork in exotic locations to highlight the importance of the theory of uniformitarianism. Focussing on endangered ecosystems, it gives a salutary lesson on the need to understand geological and life processes in the past to help us appreciate the impact that we are having on modern reef environments.   

As one reads through the book, initial unsettling thoughts about the future of these magnificent natural structures is dispelled through the carefully crafted detective novel-like story that has been woven together by Lisa Gardiner. Through learning how we are gaining a better understanding of the complexity of these structures and how conservation methods are being utilised, it gives us hope that despite the deep peril facing reefs in the modern day, there can be an optimistic future for them. Knowing why we need to study these regions and how to apply the lessons learned is an important undercurrent threaded throughout the book. 

Gardiner has created a simple yet scientifically robust narrative that can be understood by the public, yet gives enough information for those that wish to develop a deeper understanding. Reefs of Time is a much-needed book on an important area of geology and should be read by everyone interested in conservation, or who wishes to understand the importance of learning from the past. One hopes that it will act as a template for similar books in the future, as we endeavour to mitigate the impacts of human interference in our natural systems.
