It is extremely rare to see a fabulous Wren's Nest crinoid for sale as most crinoids were collected over 100 years ago. This specimen is from a very old collection and has been re-prepared to reveal the wonderful root, stem and crown. The matrix has had repair but this is normal. The Wren's Nest reef outcrop is probably the most famous Silurian location in the world. An absolute classic and extremely rare and highly sought after.
