Preserved in a large rectangular block of chalk is this stunning and rare example of this cretaceous chalk sponge. The sponge has been expertly prepared. Examples like this are very seldom seen for sale as most of them end up in museum collections. This is a particularly fine and extremely sought after specimen.
An absolute classic piece of "Beetroot stone" that has been sliced, ground and a gem polish applied to reveal the beautiful detailing of this Jurassic Stromatolite. The colour is exceptional as it is a deep, rich pink which is seldom seen. A high quality specimen.
This is a very aesthetic, architectural specimen that consists of many of these lovely large bivalves from this world famous location. The specimen is highly aesthetic and has a cut base for ease of display.
