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.

Description

This listing features a genuine Crinoid Star Stem fossil from the Lower Lias Formation of the Jurassic Period, discovered along the world-renowned Jurassic Coast at Seatown, Dorset, UK. These beautifully preserved remains provide a unique glimpse into ancient marine ecosystems that flourished over 190 million years ago.

Crinoids are a class of echinoderms, marine animals that include modern relatives such as sea stars, sea cucumbers, and brittle stars. The name “crinoid” is derived from the Greek words krinon (lily) and eidos (form), due to their flower-like appearance. Despite their nickname “sea lilies,” crinoids are not plants but filter-feeding animals that anchored themselves to the seafloor using long stalks.

Crinoid stems, like this specimen, are made up of stacked disc-like segments. This particular type features a star-shaped central pattern, making it a highly collectible and visually striking example. Crinoids first appeared in the Middle Cambrian and thrived throughout the Paleozoic and Mesozoic eras, often forming dense colonies in shallow marine environments.

The Lower Lias Formation is part of the Blue Lias Group, which is famed for its exceptional fossil preservation. Fossils from this formation provide critical insight into early Jurassic marine life and environmental conditions.

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.
