Parent H., Myczyński R., Scherzinger A., Schweigert G. (2010) Cieneguiticeras, a new genus of Tithonian oppeliids (Ammonoidea, Late Jurassic) // Geobios. Vol.43, Iss.4, P.453-463.

The new genus Cieneguiticeras, assigned to the family Oppeliidae,is described on the basis of Andean lower-middle Tithonian ammonites from Arroyo Cieneguita, west-central part of the Neuquén-Mendoza Basin, Argentina. The macroconchs are closely homoeomorphic with Neochetoceras Spath and the microconchs have a ‘glochiceratid’-type morphology. The stratigraphic range of Cieneguiticeras nov.gen. includes the lower and middle Tithonian by means of a succession of two or three species which are interpreted as members of a phyletic lineage. Ammonites from the Tithonian of Cuba, Mexico and France are more or less confidently included in this new genus. In addition to these records, very close microconchs (determined as Lingulaticeras blachkei) are also known from the Tithonian of the Western Carpathians, Northern Caucasus and, possibly, Volgian of the European Russia.
