An exquisite crinoid, or sea lily, that has been expertly prepared in the rich black matrix of the famed fossil locality of Holzmaden, Germany. Also present is the beautiful golden-toned pyrite for which the finest examples from the locality are prized. The sea lily used its stem to attache itself onto a wood or other organic material in order to float in the Jurassic seas filter-feeding on small marine organisms.
