DescriptionSeirocrinus subangularis (fossil Crinoid).jpg |
Seirocrinus subangularis (Miller, 1821) - fossil crinoid from the Jurassic of Germany. (CM 34210, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA) Crinoids (sea lilies) are sessile, benthic, filter-feeding, stalked echinoderms that are relatively common in the marine fossil record. Crinoids are also a living group, but are relatively uncommon in modern oceans. A crinoid is essentially a starfish-on-a-stick. The stick, or stem, is composed of numerous stacked columnals, like small poker chips. Stems and individual columnals are the most commonly encountered crinoid fossils in the field. Classification: Animalia, Echinodermata, Crinoidea, Articulata, Isocrinida, Pentacrinitidae Stratigraphy: Holzmaden Lagerstätte, Posidonia Shale, Toarcian Stage, upper Lower Jurassic Locality: unrecorded/undisclosed site at or near the town of Holzmaden, southwestern Germany |
