Bolca is a site of exceptional preservation of fossils (termed a konservat lagerstätte) located close to Verona, Italy. This 50 million year old limestone was deposited in the Eocene Epoch and contains over 500 species of plants, arthropods terrestrial vertebrates and most notably a lot of fish! The preservation at Bolca is so detailed that even the external colouration of the skin and internal anatomy of many of these fossils can be seen. Exploring the taphonomy (the processes that occur to a body between death and discovery) and palaeoecology (how fossil organisms lived and interacted with other organisms and their surroundings) of some of the fish from Bolca is Dr Valentina Rossi from University College Cork, Ireland. In this episode, we look at how colour patterns are preserved in a fossil moonfish and look at what that can tell us about how the species lived.
