Phil has translated 22 of Maurice Collignon's original manuscripts on the ammonites of Madagascar from the original French and compiled the results into one volume. The descriptions span the 40 years of Collignon's research first for the French colonial government and later for the Malagache Republic Bureau of Mines. Beginning in 1931 and continuing through 1971, Collignon assembled a veritable treasure trove of thousands of specimens and distilled his observations into high quality French language paleontological manuscripts.
Phil's translation collates those descriptions of genera and species, bringing relationships between the families and genera into the modern context as understood in the "Treatise On Invertebrate Paleontology Part L - Mollusca 4 Revised 1996."
This 274 page volume covers 250 species of 54 genera that existed in Madagascar at least in part during the Cretaceous Period. Families included: Nautilidae, Phylloceratidae, Gaudryceratidae, Perisphinctidae, Desmoceratidae, Silesitidae, Cleoniceratidae, and Douvilleiceratidae.
This is our desk reference, available for the first time anywhere.
