Episode description

Coccolithophores are tiny unicellular eukaryotic phytoplankton (algae). Each is covered with even smaller calcium carbonate plates called coccoliths and it is these that are commonly preserved in the fossil record. In fact, coccoliths are so small, and can be so common, that they have been able to be employed in areas other than academia.

Joining us is Dr Liam Gallagher, Director Network Stratigraphic Limited and a nannoplankton specialist. In this episode, he explains what coccolithophores are and we explore some case studies of how their coccoliths are being utilised.

This episode discusses details of recent and high-profile murder case. Whilst focus is placed on the scientific investigation, the latter part of this episode may not be suitable for all audiences.
