Arkadiev V.V. (2011) New Data on Ammonoids of the Genus Paraulacosphinctes from the Upper Tithonian of the Mountainous Crimea // Stratigraphy and Geological Correlation. Vol. 19, No. 2, pp. 238242.

The Late Tithonian ammonites Paraulacosphinctes cf. transitorius (Oppel) and P. cf. senoides Tavera from the Feodosiya section boundary Tithonian_Berriasian beds of the Crimea. These species allow the correlation of the beds recognized in the Crimea with P. cf. transitorius with the Upper Tithonian Substage of the Western European scale. Based on magnetostratigraphic data, these beds supposedly correlate with the Durangites Zone.
