Pentacrinites is an extinct genus of Crinoid, also commonly known as Sea Lily which lived from the Middle Triassic to the Eocene Period of Asia, Europe, North America and New Zealand

Their stems are pentagonal to star-shaped in cross-section and are the most commonly preserved parts. Pentacrinites are commonly found in the Pentacrinites Bed of the Early Jurassic of Lyme Regis in Dorset, England.

Pentacrinites can be recognized by the extensions (or cirri) all around the stem, which are long, unbranching, and of increasing length further down, the very small cup and 5 long freely branching arms.
