Carbon isotope geochemistry of the Frasnian–Famennian transition

Palaeogeography, Palaeoclimatology, Palaeoecology, 2002
Abstract Carbon isotope records for inorganic and total organic carbon (TOC) as well as for individual organic biomarkers show two positive excursions in the Late Frasnian with comparable shape and amplitude in δ13C. The positive shifts in δ13C can be correlated with the deposition of the Kellwasser horizons.

Effect of the Frasnian-Famennian extinction event on the stromatoporoids

Geology, 1987
Although Paleozoic stromatoporoids were drastically reduced in abundance and diversity by the Frasnian-Famennian (F/F) mass extinction event, at least 20 genera (mostly labechiids and clathrodictyids) are known from latest Devonian rocks. Some typical Frasnian genera survived the F/F crisis to die out in early Famennian time, and others took part in ...

Biostratigraphy of Famennian in Hainan Island, South China

Science in China Series D: Earth Sciences, 2001
On the basis of the faunas including conodonts Palmatolepis gracilis sigmoidalis, P. gracilis gracilis, Polygnathus germanus, which are found for the first time, and corals Cystophrentis kalaohoensis it is confirmed that the Changjiang Formation refers to the Famennian, and may correlate with the Shaodong Formation and Menggongao Formation of central ...

A new phyllocarid crustacean from the Famennian of Belgium

Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2009
A single carapace of an echinocaridid phyllocarid found in the uppermost part of the Evieux Formation at Arbre near Namur of late (latest ?) Famennian age lacks both the posterocentral and posterodorsal ridges, both characters considered to be derived ones. This makes it a member of the E. punctata group.

Discovery of Lower Famennian Stromatoporoidea in the Kuznetsk Basin

Paleontological Journal, 2008
Stromatoporoidea recorded for the first time from the Lower Famennian of the Kuznetsk Basin are described. The assemblage studied includes three new species, Actinostroma quasifenestratum sp. nov., Kyklopora tomiensis sp. nov., and Coenostroma rarum sp. nov., and three previously known species of different genera.

Chondrichthyan biofacies in the Late Famennian of Utah and Nevada

Journal of Vertebrate Paleontology, 2001
Late Famennian assemblages of chondrichthyan microremains, especially teeth, from Nevada and Utah representing two zones of different water depth are analysed and compared to formerly described pelagic chondrichthyan biofacies from the areas between S Euramerica and NW Gondwana.

Late and latest Famennian conodonts at the Malpasso section.

2017
Conodont biostratigraphic and taxonomic analysis of the Malpasso section were presented by Perri & Spalletta (1991, 1998). The abundant ammonoid fauna was studied by Korn & House (1997) and Korn (1998). In Spalletta & Perri (2001) the section was proposed as possible candidate for the subdivision of the Famennian.
