The New Mexico Museum of Natural History and Science in Albuquerque NM has in its fossil collection a number of large tarphycerids, an order containing the earliest coiled nautiloid cephalopods, from Newfoundland, Canada, originally belonging to the late Dr Rousseau Flower. Two, Loganites and Bennettoceras, were named by him but descriptions are lacking. Others presumed also to be from Newfoundlland are unidentified.
Loganites, upper left, Bennettoceras, middle left, and a large unnamed tarphycerid, bottom right. All are external views. Much of the matrix was artificially stripped away using Photoshop. Loganites is on the order of 7 in in diameter ( about 18 cm), Bennettoceras is somewhat smaller, about 5 in ( 12.5 cm). The straight portion of the unnamed specimen is about 7 in (18cm) as well. All are internal molds. All are Ordovician in age
