Sinosura kelheimense

Phylum Echinodermata; Class Ophiuroidea

Geological Time: Late Jurassic, Tithonian Stage

Size: Fossils are 17-41 mm across on a 240 mm by 145 mm matrix

Solnhofen Sinosura Brittlestar FossilsDescription: A rarely seen member of the Ophiuroidea, or Brittlestars, this is a fine example of a death assemblage of NINETEEN specimens of the genus Sinosura (17 positive and 2 negative). While starfish are more sturdily-built, the Briitlestars are more delicate, with the arms branching off from the central disc in such a way as to make the arms quite mobile (some are also termed “Serpent Stars” due to their sinuous movements). These 150 million year old deposits are famous for their exceptionally well-preserved organisms, the most famous of which are the handful of specimens of the ancient bird Archaeopteryx. They are well-positioned on this large lithographic limestone matrix, suitable representatives of this remarkable largerstatt that is sure to be a welcome addition to any collection of specimens from the region. See my other offerings for both a single specimen and another more affordable multiple assemblage.
