Crinoids are an ancient fossil group that first appeared in the seas of the Middle Cambrian, about 300 million years before dinosaurs.  The name comes from the Greek word krinon, ‘a lily’, and eidos, ‘form’. They live in both shallow water and in depths as great as 9,000 meters (30,000 ft). Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies.

ACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.

Description

This listing features a 100% genuine Crinoid Star Stem fossil from the Oxford Clay Formation, dating back to the Jurassic Period (~163 to 157 million years ago). It was discovered at Tidmoor Point, Dorset, UK, a renowned locality for Jurassic marine fossils.

Crinoids are marine animals belonging to the phylum Echinodermata, the same group as sea stars and sea urchins. They first appeared during the Middle Cambrian, over 500 million years ago, and many species still survive today. Crinoids that remain attached to the seafloor by a stalk are commonly referred to as “sea lilies”, though they are animals—not plants.

The “star stem” appearance comes from the uniquely shaped ossicles (segmental plates) that make up the crinoid stalk. These fossilised stems are often beautifully symmetrical, with star-shaped cross-sections that make them highly collectable and visually appealing.

Crinoids were filter feeders, extending their feathery arms into the ocean currents to trap plankton and other food particles. Their hard parts, especially the stalk, are commonly preserved in fossil form due to their high mineral content.

This specimen has been naturally preserved in fine marine sediment and displays the classic star-shaped segments typical of crinoid stems. Its geological origin in the Oxford Clay also places it in the same marine ecosystem that once included plesiosaurs, ichthyosaurs, and ammonites.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
