Evolution of asteroarchaediscidae A. Miklukho-Maclay, 1957 in the Carboniferous

Аннотация

This paper discusses the evolution of the family Asteroarchaediscidae, occurring in Eurasia, North America, and North Africa and used in Viséan and Serpukhovian stratigraphy. In particular, the species composition of the euryfacial genus Neoarchaediscus is very important because species of this genus are used for biostratigraphy of the Viséan–Serpukhovian boundary beds and correlation of deep- and shallow-water facies. Members of the family Asteroarchaediscidae are present in the Verkhnyaya Kardailovka Section, a candidate for the global stratotype of the Serpukhovian Stage base.
