Description: There are 3 specimens of the species Olenus truncatus on this slab of Upper Cambrian orsten limestone from Sweden. One of them is preserved as a ventral. These limestones occur as concretions in the alum shale and were sorted out during the mining of the shale. This piece comes from an old collection from the 1980s. Fortunately, the piece was not prepared at that time, so that it could be prepared with modern preparation techniques recently.

The trilobites were carefully fine prepared and present themselves harmoniously on natural matrix.

As with all my fossils, this specimen comes with a signed certificate of authenticity confirming the fossil’s authenticity.
