An unexplored ammonite “Ammonites Baeri Simonovich, Bacevich et Sorokin, 1876” from the Upper Cretaceous deposits of the Caucasian Mineral Waters region

Ammonites have been found in the upper Campanian deposits of the type locality of “Ammonites Baeri” Simonovich, Bacevich et Sorokin, 1876 in the city of Essentuki. This species is almost unknown in the literature due to the uncertainty of its features and the lack of type material. The study of the ammonites found allows us to classify “Ammonites Baeri” as belonging to the Coniacian-Maastrichtian subgenus Hauericeras (Gardeniceras).
