From editor or global species database
Fossil range Lapshina (1958) classified the deposits into the Kaezian part of the Ostrog Subgroup (Bashkirian according to Amler & Silantiev 2022), but Betekthina (1966) treated all the Lapshina species she listed as of Mazurovian (latest Bashkirian to Moscovian) age. Exact age uncertain. [details]
