Palaeobiology meets geochemistry: concretions as tombs

All but one of the papers in this thematic set derive from papers presented to the 1998 Lyell Meeting convened by John Cope and Charles Curtis under the auspices of the Joint Committee for Palaeontology, held in the Society’s apartments in February of that year. We are pleased to acknowledge the financial contributions made to this meeting by the Geological Society and the Palaeontological Association.
