metadata.name: dc.description.abstract
metadata.value: The article considers sclerobionts on the shells of the Frasnian bivalves and brachiopods of
  the east of the Main Devonian field, as well as common traces of bioerosion of biogenic and
  abiogenic substrate. In contrast to the averaged data on the Frasnian brachiopod sclerobionts,
  which demonstrate a clear dominance of auloporids, craniform brachiopods, bryozoas and
  microconchids, microconchids predominate among Frasnian bivalves sclerobionts and brachiopods
  of the Main Devonian field and among the eroding sclerobionts — the ichnogenus
  Arachnostega Bertling. Next in the degree of frequency of occurrence are cornulitids, then auloporids and eroding sclerobionts of the ichnogenus Trypanites Mägdefrau. The ichnogenus
  Arachnostega Bertling was first identified in the Frasnian rocks of this region. Some Frasnian
  sclerobionts of the east of the Main Devonian field were inhabitants of a fairly wide range of
  conditions. For example, microconchida Palaeoconchus omphalodes (Goldf.) are found both
  on shells burrowing bivalves of inhabitants of soft muddy bottom, and on shells of various
  representatives of epifauna that lived in conditions of both firmground and hardground. Representatives
  of three different ethological groups have been identified in cornulitids — fully
  cemented to the substrate; with a raised anterior part and free-living, attached only at the
  juvenile stage. The maximum morphological and ethological diversity of cornulitids was recorded
  on the bivalves of the Main Devonian field from the Dubnik beds corresponding to
  the maximum of the Frasnian regression. The active development of cornulitids in the Dubnik
  time was probably favored by the lack of competition with other groups of organisms of
  similar ethology. A fairly wide range of morphological types of cornulitids isolated within one
  stratigraphic level indirectly confirms O. Vinn’s hypothesis about cornulitids as a group of biological
  opportunists. The author proved for the first time the presence of two morphologically
  similar ichnogenera Trypanites Mägdefrau and Palaeosabella Clarke in the Frasnian rocks of
  the Main Devonian field.
