Extra details from original publication
Range. Forms which can be included within the present new genus include Praeglobotruncana loeblichae Douglas, 1969, Praeglobotruncana helvetica (Bolli) of Weidich (1984), and Praeglobotruncana praehelvetica (Trujillo) of Weidich (1984). P. loeblichae was recorded from the upper Turonian–lower Coniacian of California and Alaska (Douglas, 1969), whereas P. helvetica and P. praehelvetica of Weidich are recorded from the Turonian and the middle Cenomanian–Turonian of the Bavarian Alps, respectively (Weidich, 1984). Accordingly, the range of Badriella n. gen. is considered to be middle Cenomanian–early Coniacian.
