A large example of a crinoid fossil of the species Pentacrinites fossilis from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 265 mm (10 1/2 inches) by 240 mm (9 1/2 inches) which is large for this fossil type and it is mounted on a handmade frame that measures 330 mm (13 inches) by 325 mm (12 7/8 inches). The fossil consists of a stem section with long and detailed attachment cirri (that look like tentacles coming out of the stem: used by the animals to hold onto things) and some partial heads with long arms and pinnules. This one is unusual because it also has a completely exposed mouth section (the top of the calyx). This can be seen in the close-up images. This mouth is usually hidden inside the arms of the head and is rarely exposed like this. This would make it a great study piece or unique display piece. It is preserved in limestone with a layer of dark pyrite on the surface giving it a shine. The bespoke frame is lightweight, with the whole piece weighing just 1300 grams, making it easy to hang for display. The back of the frame has a raised margin to allow it to be hung on a nail or hook. These crinoids are very sought after and not easy to find these days and mounted examples are very hard to come by.
Around 196 million years old, this fossil would make a wonderful addition to any collection
