Working Group Upper Cretaceous Foraminifera Catalog of Maastrichtian Foraminifera
Mission and path

Mission:

we want to build a comprehensive catalog of Upper Cretaceous foraminifera. It shall be freely accessible thru the foraminifera.eu webpage.

Path:

We sample and process Upper Cretaceous rocks as a hobby out of fun. We extract the forams, photograph and identify them based on a comprehensive set of literature.

We integrate images provided by professionals. The share of images by professionals shall be about two-thirds.
Who we are

  • Hesemann, Michael: concept, sampling, processing, photographing and identification, web and database, contact to professional contributors
  • Ketelsen, Dieter: preparing fieldtrips, sampling, processing, photographing and identification
  • Raveling, Stefan: providing core-samples and from construction sites, processing, photographing and identification

  • Contributors
  • Baubkus, Werner: sampling and photographing
  • Elicki, Olaf: 239 images
  • Frenzel, Peter: 600+ images and samples
  • Friedman, Virginia: Cenomanian specimens of the Eagle Ford Formation,Texas.

    Achievements

    integration of 2689 datasets, of which
    2082 are contributed and identified by scientists.
    Each consists of an image and accompanying 24 data.

    accessibilty of images and data through the
    well structured database and query

    includes 335 genera and 842 species

    key to species for benthics

    talks on Upper Cretaceous foraminifera were given in Berlin, Hamburg, Hannover and near Schwerin

    A publication was made: Hesemann, M., Dieter Ketelsen, 2017: Index Foraminifera in chalk marl smaers at the Brodtener Ufer (Coast of the Western Baltic Sea), Geschiebekunde aktuell 33 (4): 111-117
    Actual work and plans for 2020

  • field trip to the quarry of Lägerdorf (Campanian).
  • working on Campanian material from Lägerdorf.
  • photographing of Santonian specimens provided by Stefan Raveling.
  • K-PG boundary
  • processing of samples from the field-trip to Denmark in 2017 (image)
  • photographing of forams from a well-site in the Foula Subbasin, provided by Micropress Europe
  • integrating of contributed images by Olaf Elicki
