Lot 721
Museum Quality Giant Crinoid. The Crinoid, which is known as a "sea lily", is actually an echinoderm with five-fold symmetry related to the star fish. This museum quality 17½ x 16" gray stone slab contains a 23", 240-million-year-old Traomatocrinus crinoid from the Guizhou Province of China. This giant crinoid consists of a 16" wide and 8" long Calyx (cup or flower part) with a 7" long stem. The detail is excellent, with many of the fine feather-like pinnules visible. These sieve-like pinnules were used to capture small prey, which were transported to the mouth at the center of the Calyx. This striking crinoid, positively Giger-esque in its appearance, has no restoration and is a light gray color which contrasts nicely with the dark gray matrix. Estimate Value $2,000 - 2,500
