Order Nautilida Agassiz 1847
Family Solenochilidae Hyatt 1883
Genus Solenochilus Meek and Worthen 1870
While Meek & Worthen named Solenochilus in 1870, D’Orbigny (1850) had previously referred to these cephalopods as Nautilus (Cryptoceras). Meek & Worthen proposed a name change because Cryptoceras was given to a different group of cephalopods by Dr. Barrande in 1846. The situation goes deeper because Latreille (1804) used Cryptoceras as a Hymenoptera (flying insect) genus. There is more, but to make a long story short, Nautilus (Solenochilus) became the name for this coiled, large, winged, and rapidly expanding cephalopod genus.
