 Beskrivelse:   af  Gilles Cuny 
DK 730 consists of 1 shark tooth from the Lillebælt Clay found in Trelde Næs, near Kirstinebjerg by Sten Lennart Jakobsen, which belongs to the species Isistius trituratus.

This kind of tooth is extremely rare in the Danish Eocene record. However, the main interest to declare this material Danekræ is its association with DK728, 729 and 731, which allows to keep in our collection a full record of the shark diversity of the Lillebælt Clay, diversity that was recently studied in details by Agnete Weinreich Carlsen in her Master Thesis entitled "A study of the sharks and rays from the Lillebælt Clay (Eocene) of Denmark, and their palaeoecology".

Although the sharks in the lillebælt are quite common, almost nothing has been published on them, and it is very important we keep a record of their diversity via the Danekræ collection. For this to be efficient, all of DK728-731 has to be declared Danekræ.
