Large Group of Armored Crinoids.
Crinoids can resemble a plant but are actually an echinoderm related to star fish and sea urchins. These highly unusual animals filtered various small marine animals as they were attached to the sea bottom. Jimbacrinus bostocki was an extremely unusual crinoid that somewhat resembles an armored octopus with five arms instead of eight. Jimbacrinus would anchor itself to some object on the sea bottom and use its five arms like tentacles to catch small food items swimming by. This 12" x 10" stone matrix contains 16 nearly complet calyxes (heads) and several of the five arms that each one possessed. The tiniest detail is amazing with some of the arms having very small extensions analogous to the hooks attached to the tentacles of squid. The crinoids are 3-D and are visible on both sides of the matrix with 10 Calyxes on one side and 6 Calyzes on the back side. The entire specimen can stand upright on its own to display both sides. Jimbacrinus were 260 million years old and were found in the Northwest Territories of Australia. With even one single specimen bringing hundreds of dollars, such a large mass mortality group represents an excellent buying opportunity. Add $50 for domestic shipping.
