Atlas of Maastrichtian Foraminifera

The Atlas of Boreal Maastrichtian Foraminifera is building up.
350+ images are added
They are accessible through the Atlas of Boreal Maastrichtian Foraminifera



The first goal will be to add about 600 images. In May 2013 the working group "Atlas of Boreal Maastrichtian Foraminifera" will meet and discuss how to move on. It is not clear, whether we have the capacity to add pages on single species with further explanations. There are several samples waiting to be processed. Lets see, which path we follow.

Maastrichtian Foraminifera Working Group


Bolivinoides draco draco
The Foraminifera.eu Working Group "Maastrichtian Foraminifera" has started to operate.

A Maastrichtian sample from a core-drill from Hemmoor, Northern Germany has been processed. Stefan Raveling who provided the sample did also the washing, sieving and optical imaging. SEM-imaging was done by Dr. Rosenfeldt and Michael Hesemann.

First 60 images are online at www.foraminifera.eu/hemmoor.php The material is corroded but still shows important details and ornamentation to identify single specimens.

The Working Group "Maastrichtian Foraminifera" will continue to work on this sample, samples from the Laegerdorf Quarry, also Northern Germany and from a drill-core from the Baltic Sea. Other Maastrichtian material is welcome and the group is open for more members. In case of interest you may contact us via email: michael [at] foraminifera.eu

It is planned to meet in November 2012 on a Saturday in Hamburg, Germany to discuss the project and single species. The results will be used for the related "Index Foraminifera Cretaceous" Project.

Pleistocene Sample indicating 450m lift

A sample from the Peloritani mountains in the northeastern part of Sicily, Italy indicates that the terrain has been lifted by 450m or more within only 1,8 Mio. years since the early Pleistocene.

The material is taken from the Salice Outcrop lying today at 340m above sealevel. It contains several Globorotalia inflata, which first appeared in the latest Pliocene/Early Pleistocene. Geological studies place the Salice outcrop into the Early Pleistocene spanning from 1,8-0,8 million years BC.

The sample contains about 40% planktonic foraminiferal tests, which indicate water-depth of at least 100m at the time of deposition. Studies carried out in different parts of recent oceans proof a strong correlation between water-depth and share of planktonic foraminiferal tests in the sediment.
