Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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 ...

Aramazdospirifer orbelianus (Abich, 1858) n. comb., a new cyrtospiriferid brachiopod genus and a biostratigraphically important species from the lower Famennian (Upper Devonian) of Armenia [PDF]
Comptes rendus. Palevol, 2022 The new genus Aramazdospirifer n. gen. (Cyrtospiriferidae) is erected to include Spirifer orbelianus Abich, 1858 from the lower Famennian of Central Armenia as its type species and to refute long-standing claims related to the affinities of the latter ...

GSA Bulletin, 2020 The Devonian Period experienced significant fluctuations of atmospheric oxygen (O2) levels (∼25–13%), for which the extent and timing are debated. Also characteristic of the Devonian Period, at the Frasnian–Famennian (F–F) boundary, is one of the “big ...

Extreme abundance of ammonoids in mass accumulations from the Late Devonian of the Moroccan Anti-Atlas [PDF]
Acta Palaeontologica Polonica, 2022 The eastern Anti-Atlas is renowned for its highly fossiliferous outcrops of Devonian rocks. Ammonoids occur in rock-forming numbers at many localities in the Tafilalt and Maïder.

On two cyrtospiriferid brachiopod species from the lower famennian of central Armenia
Proceedings of NAS RA. Earth Sciences, 2022 In an effort to describe the brachiopod diversity of the lower Famennian Aramazdospirifer orbelianus brachiopod Zone of Central Armenia (coeval to the Palmatolepis crepida conodont Zone), our attention is here focused on the description and illustration ...

Devonian (Emsian-Famennian) Palynomorphs [PDF]
Journal of Micropalaeontology, 1985 Abstract. EMSIANMiospore assemblages which can be positively assigned to the Early Devonian have, to date, only been recorded from core material from Well A1-33. Assemblages of Emsian age were recorded from the interval 8079 to 8091 ft. whilst assemblages from 8055 to 8076 ft.
