    Seirocrinus subangularis
    Lower Jurassic
    Posidonienschiefer Formation, Holzmaden, Baden-Württemburg, Germany

    The Crinoid, known also as the Sea Lily or Feather Star, is one of the world's so-called "living fossils", with species still to be found in today's oceans from Indonesia to the Caribbean. Their fossils are also found all over the world, but the most beautiful and desirable are those from the Posidonia shale beds of Holzmaden, in southern Germany. This Lower Jurassic formation is renowned for its beautifully preserved fossils from the Tethys Ocean, which existed between the continents of Gondwana and Laurasia for much of the Mesozoic Era. The name of the formation was taken from the abundant Posidonia bronni, small clams, found in the shale, but it is host to a wealth of other flora and fauna. These include some of the most spectacular Ichthyosaur fossils to be found anywhere in the world, and of course the giant Crinoids. The strong, dark color of the shale serves as a beautiful background to the delicate, curvaceous neck of the fossil, preserved in stunning detail. Artfully prepared, the whole piece stands out with remarkable three-dimensionality, highlighted by the subtle shimmer of pyritization from crown to root. It remains attached to a piece of ancient petrified wood, surrounded by what appear to be a number of small mollusks. Crinoids often attach themselves to the ocean floor, but are known also to anchor themselves to pieces of free-floating driftwood, and it was discovered, through footage shot in 2005, that some Crinoids can even "uproot" themselves and use their arms to scurry across the sea bed at a surprising speed if danger threatens. A large, beautiful, and extremely impressive plaque, representing one of the finest fossil formations in the world, it measures a dramatic 84⅜ x 44¼ inches.

    It would indeed have been much simpler to work with a local auction house, and we had local options. But we never once regretted going with Heritage.
