Report 2005 of the Lutetian-Bartonian Boundary Working Group The work of the Lutetian-Bartonian Boundary Working Group during 2004 and 2005 has focused on identifying stratigraphic events which could serve as guide horizons for the base of the Bartonian. The early focus of the working group was on identifying a biostratigraphic event that could serve as […]

Report 2006 of the Lutetian-Bartonian Boundary Working Group The work of the Lutetian-Bartonian Boundary Working Group during 2006 has continued its focus on the base of magnetic polarity chron 19N as a guide horizon for the base of the Bartonian. For the base of chron 19N to be a useful guide horizon for the base […]
Report 2007, 2008 and 2009 of the Lutetian/Bartonian Boundary Working Group: The work of the Lutetian-Bartonian Boundary Working Group during 2007, 2008 and has continued its focus on the base of magnetic polarity chron 19N as a guide horizon for the base of the Bartonian. For the base of chron 19N to be a useful […]
Report 2010 of the Lutetian/Bartonian Boundary Working Group Several scientists, coordinated by Coccioni (University of Urbino), re-investigated the Middle Eocene interval from the classical Contessa Highway section, near Gubbio, a possible candidate for the Bartonian GSSP. In search of a possible candidate section for the base Bartonian GSSP, the Middle Eocene sedimentary succession of the […]
Report 2011 of the Lutetian/Bartonian Boundary Working Group In search of a possible candidate section for the base Bartonian GSSP, the Middle Eocene sedimentary succession of the Contessa Highway section (CHS, near Gubbio, central Italy), was re-visited. Historically, this section has been the focus of important biostratigraphic studies on calcareous plankton (foraminifera and nannofossils) and […]
Annual Report 2008 of the Calcareous Nannofossils Working Group A short workshop of the Working group has been held during the 12 International Nannoplankton Association Conference (INA 12) in Lyon in September 2008. The main objectives of the working group should be: – to develop a taxonomic atlas and, in collaboration with the INA at […]
Annual Report 2009 of the Calcareous Nannofossils Working Group During this first year the Paleogene calcareous nannofossil working group has organized several meetings: -November 2008 at the University College of London under the banner of INA and the ISPS hosted by Paul Bown. During the meeting, attended by around 20 participants, we have agreed on […]
Annual Report 2010 of the Calcareous Nannofossils Working Group During this year the Paleogene calcareous nannofossil working group has continued its researches, investigating the major calcareous nannofossil turnover and distribution across the Danian-Selandian boundary, the PETM interval, the Ypresian/Lutetian and the Eocene/Oligocene boundary. Furthermore, in 2009-2010 a comprehensive Paleogene species list was uploaded to the […]
Annual Report 2011 of the Calcareous Nannofossils Working Group The Paleogene calcareous nannofossil working group has continued its work towards a major revision of the early Fasciculithus and the calcareous nannofossil turnover across the Danian-Selandian boundary. Furthermore, has been continued the discussion on reticulofenestrids, initiated in Yagamata (September 2010) during the International Nannoplankton Association, in […]
Annual Report 2012 of the Calcareous Nannofossils Working Group During 2012 the Paleogene Calcareous Nannofossils Working Group continued the work on taxonomy and evolution of the early fasciculiths during the Late Danian Event and the Danian –Selandian boundary. The WG keeps on also the debate and investigations on the reticulofenestrids, a dominant coccolithophore group for […]
