Talk:Ophidioceras

Taxonomic Position
Sepkoski 2002 has both Ophidioceras and Ophioceras as separate genera in the Orthocerida, where Ophidiceras was previously placed. . This may be based on the apparent close relationship to Lituites, also misplaced in the Orthocerida. (ibid)

Those who have worked closely with the Tarphycerida, not limited to Rousseau Flower, W.M Furnish, and Brian Glenister, recognize the affinity of the Lituitids and Ophioceras  to that group, in which this genus is now included. J.H.McDonnell (talk) 22:01, 26 June 2011 (UTC)
