Calcification on an Unstable Substrate: Marginal Growth in the Moilusk Pecten diegensis

George R. Clark II 1

1 Department of Geology, University of New Mexico, Albuquerque 87131

Observations of the growing margin of Pecten diegensis show that calcification can occur on an unstable substrate, although this initial shell material is quite disordered. Later growth on the inner surface of the disordered material soon becomes ordered, which suggests that the calcification process benefits from the stability of a mineralized substrate, but does not utilize the substrate as a physical or stereochemical template.
