This specimen has been carefully prepared from a hard phosphatic nodule over many hours. This is a skull from a turtle which indeed is very rare and highly sought after amongst collectors. The lower jaw is not present, however the top pallet is, as well as the well defined eye sockets. Collectors will appreciate how rare the specimen is - one for the serious collector.
Although this is a partial starfish, starfish remains are fairly rare from this classic and much sought after location. The detail throughout the specimen is fine and would make a lovely drawer specimen.
