Goecoma Solnhofen BrittlestarDescription: A rarely seen member of the Ophiuroidea, or Brittlestars, this is a fine example of Geocoma carinata. The genus is also known from the Cretaceous deposits of Lebanon where Geocoma libanotica is often seen. These Brittlestars are over 50 million years older, showing that the genus was quite long-lived. 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. It is well-positioned on its square lithographic limestone matrix, a suitable representative of this remarkable largerstatt that is sure to be a welcome addition to any collection of specimens from the region.
