Location Description:

The cliffs at the eastcoast are located in the Jutland region in Denmark. The cliffs consist of claylayers from the Paleocene and Eocene (part of the Paleogene period). You can find various fossils (like shark teeth) in the clay.

Warning: The cliff was in 2007 almost all overgrown, and there is almost no erosion taking place. The possibillities to collect fossils are very slim!!!

Between the pebbles on the beach you can find erratics which were transported here in the iceages. The fossils originate from the Ordovician , Silurian and Cretaceous periods.

Trelde Næs is only a small part of the exposed sediments along the Kleine Belt. The sediments continue from Trelde Næs to Kristinebjergskov. At Kristinebjergskov a small past of Oligocene must be present.

The sediments along the Kleine Belt are mostly from the Eocene and are part of the Rønæs (middle Ypresian) and Lillebælt (upper Ypresian to Lutetian) formations. These formations consist of yellowish claylayers and layers with concretions. These are not fossiliferous and contain not much chalk, because the sediments were formed in an environment low in oxygen.

Specific layers are more fossiliferous. Especially the concretionlayers are rich in tracefossils, and parts of crabs. These concretions are often found washed together on the beach. The grey/black layers contain much chalk and organic material, and montain macrofossils like sharkteeth, parts of bone fishes, crinoid stems, brachiopods, coccoliths etc.

Because of the organic content, much material is pyritized. Especially the stems of the crinoid Issielicrinus subbasaltiformes are pyritized and can be found in large numbers. Within the barite concretions on the beaches you can find parts of bone fishes, and pyritized wood.

Finally. The coastal cliffs are eroding fast. Every year large parts of the cliffs glide into the sea. Because of this it it impossible to give specific locations where you can find fossils. The ships beacon at Trelde Naes had to be rebuild thee times the last century because of the erosion.

Directions:

The cape is located in the Jutland region at the Danish eastcoast, north of Fredericia. East of the "Trelde Camping" is a parking site. From here you can go walking to collect fossils. Look carefully between the outwashed material on the beach.

Finds:

From the claylayers: shark teeth (up to 1 centimetre; more than 30 known species), fish remains, stems of crinoids (Iselicrinus subbasaltiformis), gastropods (i.e. Pinnae, Mytilus and Nucuua) and crabs. The gastropods and crabs can be found inside the brown manganese balls. You can also find tracks of crabs and other animals (i.e.Rhizocorallium and Zoophycos).

Erratics which were transported here in the iceages: corals, brachiopods, sponges, stems of crinoids from the Ordovician , Silurian and Cretaceous periods.
