Each bid is for ONE sample of Devonian microconcentrate rich in conodont remains.

The material is from the Grassy Creek Shale and is upper Devonian in age. We have looked at a typical sample and have counted over 100 conodonts in the sample. Housed in a small gel capsule similar in size to a vitamin tablet but it is rich in fossils.

This is rarely seen but wonderful material suitable for any collector with a microscope.
