Lot 1726
Book-end Sized Block of Crinoids and Stems From Morocco. Crinoids are called sea lillies because they resemble a plant but are actually related to starfish with their five-fold symmetry. This large 8 x 7 inch block has crinoid crowns and stems on one side and stems on the other. Somethimes a group of crinoids were buried together as a result of a 410-million-year-old disaster such as a mud slide. That is the case with this remarkable specimen which has one side filled with partial crinoid crowns of the species Scyphocrinites with their delicate feeding arms with pinnules, comb-like filtering nets to capture micro organisms. the other side of the block is filled with spring-like crinoid stems. This well-prepared fossil has been expertly prepared to stand upright and could be used as a book-end or just as an impressive display piece. For domestic shipping, add $20.
Estimated Value $350 - 600.
