A lovely example of this burrowing shipworm which is approximately 50 million years old. The specimen exhibits a thin slice which is packed both sides, ground gem smooth and finally polished to reveal excellent detail. Very nice study fossil for the collector.
Preserved in a squared block of dark limestone is this beautiful carboniferous bivalve. The detail throughout the specimen is very fine and thiswould make a lovely addition to any collection. One for the drawers.
