Some notes on a variability of Bothriolepidids (Placodermi, Antiarchi): unusual specimen of Livnolepis Heckeri (Luksevics) from the famennian of Tver region, European Russia

Известия высших учебных заведений: Геология и разведка, 2019
The fragment of the skull cap of placoderm Livnolepis heckeri (Luksevics) from the Bilovo Formation (Famennian, Upper Devonian) near the Bilovo Village of Tver Region has been described.

Famennian (Upper Devonian) conodont zonation: revised global standard [PDF]

Bulletin of Geosciences, 2017
The revision of the Famennian part of the “Late Devonian Standard Conodont Zonation” is based on the inequivalence between biozones and time, and the rejection of the presumed single phyletic concept on which the previous zonation was based. It is also intended to simplify the zonation, eliminating the zonal groups named after only one taxon, and ...

Tabulate Corals after the Frasnian/Famennian Crisis: A Unique Fauna from the Holy Cross Mountains, Poland.

PLoS ONE, 2016
Famennian tabulate corals were very rare worldwide, and their biodiversity was relatively low. Here we report a unique tabulate fauna from the mid- and late Famennian of the western part of the Holy Cross Mountains (Kowala and Ostrówka), Poland.

Stratigraphic distribution and systematic composition of the Middle-Upper Devonian placoderms (anti-archs) from Central Kazakhstan

Известия высших учебных заведений: Геология и разведка, 2016
The stratigraphie distribution and systematic composition of the Middle-Upper Devonian remains of antiarchs from the sediments of Central Kazakhstan are analyzed. Central Kazakhstan ichthyofauna contains mainly endemic taxons of antiarchs.

Alpinites and other Posttornoceratidae (Goniatitida, Famennian) [PDF]

Fossil Record, 2002
The rediscovery of the supposedly lost type allows a revision of Alpinites Bogoslovskiy, 1971, the most advanced genus of the Posttornoceratidae. The type-species, Alp. kayseri Schindewolf, 1923, is so far only known from the Carnic Alps. Alp.

An exceptional diverse trilobite ichnofauna from the uppermost Devonian of Anti-Atlas, Morocco

Acta Palaeontologica Polonica
We present a highly diverse ichnoassemblage of latest Devonian (Famennian) age from the eastern Anti-Atlas of Morocco, dominated by trilobite and other arthropod trace fossils.

Parasitism as a Long-Lasting Interaction-First Evidence From Paleozoic Corals. [PDF]

Ecol Evol
The peak of reef development in the middle Paleozoic resulted in a dense network of interactions between corals and their symbionts. The long duration (longevity) of one of the most common relationships, parasitism, has remained unevidenced so far. Here we report on a tabulate coral infested by parasites, where, based on growth bands, the duration of ...

Enhanced continental weathering and its marine environmental effects in the late Devonian: Constraints from strontium isotopes of carbonate rocks in South China

地质科技通报, 2022
The Frasnian-Famennian extinction in the late Devonian was one of the largest mass extinction during Earth's history, which was believed to be caused by the plant landing-indued intensification of terrestrial chemical weathering and the consequent ...
