PFOOLEY Posted March 26, 2018 Share Posted March 26, 2018 While on an adventure with @Pilobolus, exploring the Dakota Sandstone and underlying shales, I found something very exciting*... ...my first coiled Nautiloid! Coiled Nautiloid Upper Cretaceous (Cenomanian) Paguate Member of the Dakota Formation Sandoval County, New Mexico Now, after a bit of research, I write here to lean on this Forum for assistance with identification. I find that this specimen sits well in the genus Kummelonautilus...what say you? Many thanks for your help, -P. *Bryan can attest to my yelling and jumping around. @FossilDAWG 5 1 "I am glad I shall never be young without wild country to be young in.

Ludwigia Posted March 26, 2018 Share Posted March 26, 2018 It may also be a Cymatoceras. Are there any remnants of the shell on it? 3 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Al Dente Posted March 26, 2018 Share Posted March 26, 2018 I did a quick Google search and found an article that discusses two Nautiloids from the Cenomanian of New Mexico. The paper is titled "Cenomanian (Upper Cretaceous) Nautiloids from New Mexico". A quote from the abstract- "The only occurrences known are Pseudocenoceras largilliertianum (d'Orbigny, 1840) in the Acanthoceras amphibolum zone of Cerro de Cristo Rey in Dona Ana County, N. Mex., and Angulithes fleuriausianus (d'Orbigny, 1840) in the A. amphibolum zone in Valencia and McKinley Counties, N. Mex." 4 Link to comment Share on other sites More sharing options...

Heteromorph Posted March 26, 2018 Share Posted March 26, 2018 Beautiful specimen! I have found several nautiluses in my neck of the woods but never that complete and with the sutures so well defined. Nice find! Not sure if this helps, but here are a few links with Cenomanian nautiluses. The first link is the Grayson formation and the second and third links are the Del Rio Clay formation. The nautiluses pictured from the Grayson are not as well preserved as your’s and do not show the sutures nearly as well. They are all Cymatoceras sp. The nautiluses pictured in the second and third links are pyritized micromorphs from the Del Rio Clay so they show the sutures better. Almost all ammonites and nautiluses found in the Del Rio Clay are pyritized micromorphs. According to this the only species of nautilus in the Del Rio Clay is Cymatoceras hill. I must admit that since this paper is from 2000 some of the information therein is outdated so perhaps other nautilus species have since been discovered in the Del Rio Clay.
