pforams@mikrotax - Introduction

This site is intended to grow into a major reference source for the taxonomy of planktonic foraminifera. These beautiful microfossils are a key tool in modern geological research widely used in biostratigraphy, palaeoceanography and study of evolutionary pattern and process. Consequently they are used by a diverse set of students, academic researchers and industrial geologists all of whom need data on their taxonomy, identification, and geological ranges. The site is not aimed at any particular set of users but to act as a central reference source accesible to anyone interested in the group.

The site has essentially been created by combining data from previous databases and syntheses - especially the Chronos database - and migrating it into a database system - mikrotax - initially created for the Nannotax website. The project to do this has been funded by a UK Natural Environment Research council grant to Profs. Bridget Wade and Paul Bown of University College London.

A few features of the site

Coverage to date and plans

noegene pf images Extant and Neogene (200 taxa, 380 images)
  • Basic coverage of the Neogene and extant taxa, excluding taxa which originated in the Oligocene. This part is a work in progress with most content compiled from standard references, especially Kennett & Srinivasan (1983). We would greatly value any input.
paleogene pf images Paleogene (300 taxa, 1150 images)
  • Oligocene - no coverage yet but an Atlas of Oligocene Planktonic Foraminifera has been produced by the Paleogene Planktonic Foraminiferal Working Group (lead by Prof. Bridget Wade). This volume has been submitted as a Cushman Foundation special publication, and the content will appear here after publication.
  • Eocene - rather comprehensive and up to date coverage, using content from the Atlas of Eocene Planktonic Foraminifera (Pearson et al. 2006), as prepared between 1997 and 2006 by members of the Eocene Working Group
  • Paleocene - rather comprehensive and up to date coverage, using content from the Atlas of Paleocene Planktonic Foraminifera (Olsson et al. 1999), as prepared between 1987 and 1996 by members of the Paleocene Planktonic Foraminiferal Working Group
mesozoic pf images Mesozoic (500 taxa, 1130 images)
  • Extensive content derived from the Chronos online database developed by the Mesozoic Planktonic Foraminiferal Working Group. Work on this part of the database is under active development by the working group, lead by Brian Huber and Maria Rose Petrizzo. Please contact them if you would like to assist.
catalog pf images Catalog (2200 taxa, 2800 images)
  • This is a separate database of original descriptions and type-specimen illustrations. Much content has been transfered from the Chronos database (including many new images of type-specimens and translations of original descriptions) and additional content is being added.
