    Abstract

    A historical perspective on our understanding of the formation of ostracod valves and what they consist of is presented here, together with the history of investigations on the chemistry of ostracod valves. It is now clear that ostracod valves are made of 3 distinct layers consisting of calcite crystallites/rhombs that are held together by a significant network of organic fibrils which may also contribute to the trace elemental composition of ostracod valves when analysed by solution chemistry. The outer epicuticle of ostracod valves, when well preserved such as in modern material, contributes to an enrichment in magnesium, and this ought to be taken into account when interpreting the Mg/Ca of ostracod valves for use with water temperature reconstructions. Recommendations about the analytical techniques used for chemical analysis of ostracod valves are presented.
