Miocene, mud and more: Miste 2013

Bram Langeveld (The Netherlands), Colin van Elderen (The Netherlands) and Stef Mermuys (The Netherlands) ‘Miste’… This word has an almost magical meaning for many fossil collectors in The Netherlands and neighbouring countries. That is because the extremely fossiliferous Miste Bed lies close to the surface around the municipality of Winterswijk-Miste, which, in turn, lies close to the Dutch-German border in the Eastern Netherlands (Fig. 1). The Miste Bed (Aalten Member, part of the Breda Formation) was deposited about 15Ma (during the Middle Miocene), in a shallow subtropical sea. The fossils preserved in the sandy sediments are extremely diverse: over 600 species of molluscs (Janssen, 1984; Parren, 2005) and dozens of species of sharks, rays (Bor et al, 2012) and bony fish (Hoedemakers and Van Hinsbergh, 2013) have been found, but also marine mammals (Schneider & Hessig, 2005), sea stars (Jagt, 1991), sea urchins, bryozoans and corals.

However, this fossil wealth is not easily accessible. To be able to assemble a decent collection, you need to dig a rather large exposure. Establishing a large hole reaching into the Miste Bed is a lot of work, because you need to excavate approximately 4m on private property. A number of digs have previously been organised at Miste, of which at least three were by the Dutch ‘Werkgroep voor Tertiaire en Kwartaire Geologie’ … Read More
