An wonderful display of Holzmaden Harpoceras & Dactylioceras ammonoid fossil plate measuring 4 feet. The Posidonia shale encapsulates these varieties of inclusions that have absorbed surrounding mineral deposits to form pyrite within these palaeontological shells. A process which has taken over 180,000,000 years.

Now excavated and prepared revealing detailed preservation with the conservation of the fossilised Jurassic layers in the ground. The Posidonia shales of the Jurassic formed part of the ancient Ocean referred to as the Tethys creating a wonderful contrast of gold pyrite against jet black Holzmaden shale to curate a dynamic interior-styled wall feature.

These Holzmaden shale deposits are world renowned for the unique formations they wield and continue to do so, however, with only a few locations with an environment that has allowed such fine preservation exist today. Posidonia shale specimens can be found at the Museum Hauff, Holzmaden, as well as many other museums around the world.
