In the Antwerp area, the Miocene is represented by the early Burdigalian to Serravallian Berchem Formation (Edegem, Kiel and Antwerpen Sand Members) (e.g. De Meuter & Laga, 1976; Laga et al., 2001; Louwye & Laga, 2007) and the Tortonian Diest Formation (Deurne Sand Member) (Louwye, 2002).

For over a century, temporary construction sites in and around the city of Antwerp gave the opportunity to study these Miocene deposits. While the Edegem Sands are very poorly known, selachian remains are relatively common in the Middle Miocene Antwerp Sands (Langhian - middle Serravalian), consisting of glauconitic black-green sand with several Glycymeris deposits.

Recently, also the Burdigalian Kiel Sands proved to contain a much diversified shark assemblage (Everaert et al., 2019; De Schutter & Everaert, 2020), fairly similar to the fauna of the overlying Antwerp Sands. To the contrary, the shark assemblage of the late Miocene Deurne Sands, only rarely exposed, is different with the (re) appearance of e.g. the genera Oxynotus, Mustelus, Lamna, Pristiophorus... in our region (Hoedemakers & Dufraing, 2015). We can also note the relative abundance of teeth of Isurus subserratus (I. escheri).
