Two Devonian Pyritized Brittle Stars (Furcaster) - Bundenbach, Germany

This is a pair of Devonian-aged, pyritized brittle stars from the Hunsrück Slate of Germany. All of the organinc material has been replaced by pyrite. They're both likely of the genus Furcaster, however it's difficult to tell with the folded specimen. The larger brittle star is 2.6" wide (longest measurement) and the smaller is 2.1" wide (longest measurement).

Comes with an acrylic display stand.

Most of the Bundenbach quarries have been closed for some time, so a very limited amount of material is coming to market from this area.

The lower Devonian (lower Emsian) slates from Bundenback have been quarried for roofing material for centuries. Quarrying continued until the 1960s, when the competition from cheaper synthetic or imported slate resulted in production decline. The last pit closed in 2000. Mining of Hunsrück slate was important for the discovery of Paleozoic fossils. Although not rare, fossils can only be found through extensive mining of slate and time consuming preparation. Fossils are hard to see lying under the surface of dark slate. In 1970, Wilhelm Stürmer, a chemical physicist and radiologist developed a new method to examine the Hunsrück slate fossils using medium energy X-rays. The Bundenbach “Hunsruck Slate" is famous for yeilding one of the most important assemblages of Paleozoic fossils, with 260 animal species including mollusks, echinoderms and arthropods - of which the phacopid trilobite Chotecops is certainly the most abundant.
