Excellent examples of bivalve fossil specimens which show the shells have been agatised, giving them an orange almost semi transparent colour and vitreous lustre, the morphology of the shells have been preserved very well as agate weather or deteriorates almost not at all as opposed to other minerals at the surface. The shells are between 20 to 40 mm in size and come from Morocco, unfortunately, for the time being, we do not have much more information regarding them such as specific species or age. But the unique agatisation of the samples makes them much more interesting to observe. Supplied in lots of 5 pieces, they come packaged in a polythene bag with information label.

Specimens of Puddingstone, collected from Hertfordshire, UK. Puddingstone is a variation of conglomerate, which is term used to describe a coarse grained sedimentary rock, featuring large, well rounded clasts in a finer grained matrix. It dates back to the Paleocene to Eocene period around 56 millions years ago. This particular rock is composed almost entirely of silica and has no porosity, likely contributing to its notorious hardness. This rare rock is only found in quantity at one locality in Hertfordshire. As such, it is becoming exceedingly difficult to obtain. This rock is available in multiple sizes and each piece comes supplied in a white card tray with information label.
