A stunning and rare example of a crinoid fossil of the species Pentacrinites fossilis from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 150 mm (5.9 inch) across and is around 32mm thick, making it large for this fossil type. The fossil is rare as it is incredibly well preserved on both sides, with a complete head with arms and pinnules preserved in three dimensions on one side, and lots of detailed stems preserved on the other side. It is preserved in limestone with a thin layer of golden-coloured pyrite. The golden colour on the stems is particularly impressive and give it an alien-like appearance. These crinoids are very sought after and not easy to find these days and this one is a fine example. It is a heavy piece, weighing 685 grams.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
