A little known odontaspid shark from the Antwerp Sands Member (Miocene, Hemmoorian) and some stratigraphical remarks on the shark-teeth of the Berchem Formation (Miocene, Hemmoorian) at Antwerp (Belgium)

The Berchem Formation (Miocene, Hemmoorian) was studied in a temporary outcrop at Berchem (province of Antwerp, Belgium). Three shark associations were collected in the various deposits of this section, offering basic information for correlations with other Miocene deposits. Teeth of a quite common, but little known odontaspid shark were collected and are described in detail in this paper. The available section was measured in detail and a large number of shark-teeth could be collected in the various layers. This material contains many teeth of a little known odontaspid shark, which are described in this paper in detail. Furthermore it was the first time that the shark species Hemipristis serra Agassiz, 1843 was collected in situ in the Belgian Tertiary deposits. Three shark associations could be distinguished by comparison of the material from the various beds.
