DESCRIPTION: This is a gorgeous example of a Seirocrinus crinoid fossil derived from the world-famous shale of the Posidonienshiefer Formation, Holzmaden, Germany. 

This phenomenal specimen is situated upon a majestic slab of Holzmaden shale having dimensions of 172 cm x 81 cm (67.3 inches x 31.9 inches).  Four stems are affixed to a jet black log with circumscribing pyrite, with each of the stems gracefully flowing upwards in elegant, variably interwoven arcs to culminate in expansive, glowing pyritized crowns fanning upwards and outwards, having respective widths of 40 cm, 28 cm, 28 cm and 13 cm.  The glory and exquisite beauty of this specimen both in part and in its totality is truly beyond words.
