"Cephalopods of Subclass Ammonoidea and especially the Mesozoic forms known in the vernacular as 'ammonites' are amongst the most abundant and well known of all fossils."1 Ammonites were a subclass of cephalopods (squid, octopus) with coiled shells, complex sutures (lines of fusion), and septa (a partition or wall between two cavities). Fossilized remains of ammonites may be found in virtually. Key words: ammonites; Cretaceous; Coahuila, Mexico. ***** In the middle s, the mining engineer for the properties then owned by ASARCO at Sierra Mojada, Coahuila, was Frank Wingfield. In , W. S. Adkins received from Frank Wingfield a small collection of ammonites of the genus Hysteroceras.
To get the Cretaceous ammonites you need "Treatise on Invertebrate Paleontology L(Mollusca 4 Revised)". I have no financial interest in the university press and can very highly recommend the books. There is supposed to be a revised volume on the Triassic/Jurassic ammonites "coming out real soon now". Fossil material. The first set of ammonite samples consists of the outer shell wall as well as jaw elements of Baculites sp. (smooth) from the Upper Cretaceous (lower Campanian) Gammon Ferruginous Member of the Pierre Shale, Butte County, South Dakota (Fig. 2) (see for locality information). This locality was selected based on the abundance of extremely well preserved specimens of Baculites.
