5.8" Pyritized Crinoid (Taxocrinus) Fossil - Bundenbach, Germany
This is a rare, pyritized crinoid of the species Taxocrinus stuertzii, collected from the famous, Lower Devonian Hunsrück Slate of Bundenbach, Germany. It is preserved in great detail on a large piece of slate. Including the stem, the crinoid is about 5.8" long, and lays on a 9.4 x 7.6" slate slab.
It comes with an acrylic display stand. There are repaired cracks through the crown where the rock chipped away during collection.

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 and time-consuming preparation: fossils are hard to see lying under the surface of dark slate. But 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 yielding one of the most important assemblages of Paleozoic fossils, representing 260 animal species including mollusks, echinoderms and arthropods, of which the phacopid trilobite Chotecops is certainly the most abundant.
