Research

Research interest

Between 1969 and 1997 I used to be curator of Cainozoic Mollusca at the National Museum of Geology an Mineralogy (nowadays part of Naturalis, The Netherlands). Here I was, apart from editorial work for both Contributions to Tertiary and Quaternary Geology and Scripta Geologica, predominantly occupied with collecting and the study of benthic molluscs from the North Sea Basin and other European regions. During these years, the collection, already very significant for Indonesian fossil molluscs, was greatly enlarged, also with the help of many friends and colleagues.

Many papers on various subjects appeared from 1958 onwards (see below for a list starting 1969). From c. 1980 onwards I specialised more and more on fossil holoplanktonic Mollusca, the so-called Heteropoda and Pteropoda. What was started as a short-term project turned out to be a lifetime occupation. These planktonic snails have very interesting morphological, systematical, evolutionary, biogeographical and biostratigraphical aspects.

In 1997 I retired and moved, together with my wife Edith, to the Isle of Gozo (Malta). Ever since I have remained an active researcher, mostly dealing with holoplanktonic molluscs, but occasionally venturing back in the benthos as well. A number of grandkids made us return to Holland mid 2013, where we now live in Katwijk, comfortably close to the Naturalis museum.

Work on the holoplanktonics continues, but I also return every now and then to fossil benthic molluscs, especially so because of the increased interest among non-professional palaeontologists for the Miocene and Pliocene North Sea Basin assemblages, as e.g. demonstrated by the active Miste-Facebook page. Since 2012 I also returned as managing editor of the periodical Cainozoic Research, edited by the Tertiary Research Group and the Werkgroep voor Tertiaire en Kwartaite Geologie.

You can find many data on the beautiful planktonic snails, both fossil and Recent, as well as more details of my work on my own website that, however, is in need of a good update.

Collaborations

Peijnenburg (Naturalis), Dr Rebeca Gasca (Plymouth University), Dr Brent Wilson (University of the West Indies, St. Auguststine, Trinidad & Tobago), Dr James Goedert (Burke Museum, Washington), Dr Marco Taviani (CISMAR, University of Bologna), Dr Ronald Janssen, Senckenberg Museum, Frankfurt am Main), Dr Frank P. Wesselingh (Naturalis)

Collections

The Naturalis Fossil Mollusc Collection contains one of the larger accumulations of fossil holoplanktonic Mollusca of the world. This collection, different from the main mollusc collection, is arranged systematically and not according to age or locality. Over 11.000 samples are represented, among which many primary and secondary types. The most important material is from the North Sea Basin, SW France (Aquitaine Basin) and the Mediterranean area, inclusive of Malta.

Many Recent holoplanktonic molluscs are available in the Naturalis department of Recent Mollusca, predominantly from the Atlantic Ocean (CANCAP expeditions), but also from the Caribbean and from Indonesia.
