Les Desmoceratidae Du Menabe

The Manzanita Lab library contains some original manuscripts authored by the noted French paleontologist Maurice Collignon.  As time permits, Phil will be producing meticulously scanned and printed copies of these extremely rare works.  Here is an opportunity to own a true copy of a manuscript in which Collignon described dozens of ammonite species for the first time.
We begin with the 1961 Volume 31 of the Annales Géologiques De Madagascar.  "Ammonites Néocrétacées Du Menabe (Madagascar) VII. -- Les Desmoceratidae."

Description Of Species

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 on Madagascar ammonite identification.  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 on Madagascar ammonite identification, available for the first time anywhere.
