Jean-Pierre Cuif is a Professor in the Department of Geology at the Université de Paris-Sud II, Orsay, France. Since 1980 his research team has developed a specialized approach to the mineralized units that built the calcareous skeletons of invertebrates through Earth history. In addition to basic research on distribution and composition of the organic compounds associated with the mineral phase, ...

Yannicke Dauphin is an Assistant Professor at Université de Paris VI (Pierre et Marie Curie), Paris, France. She worked in Jean-Pierre Cuif's biomineralization research team at the Université de Paris-Sud II. After focussing on cephalopod shells, she has extended her research on the structure and composition of modern and fossil molluscs, corals and vertebrate skeletons. James E. Sorauf taught sedimentology and paleontology at the State University of New York at Binghamton from 1962 until becoming emeritus in 2001. He has published approximately seventy papers in peer-reviewed journals on skeletal structures of modern corals and on systematics and paleobiology of fossil corals ranging in age from Cambrian to Pleistocene. He is a former co-editor of Fossil Cnidaria and Porifera. He was a Trustee of the Paleontological Research Institution in Ithaca, New York for many years, serving as President of their Board of Trustees from 1988 to 1990. Show Less
