Orthoceras monument on steel base handcrafted and expertly prepared, presenting the fossil orthicon specimens inner chambers creating this impressive Orthoceras sculpture, surmounted onto a stainless steel base. The Orthoceras has been polished to reveal the mineral sedimentations. This exhibits an array of small fossil shells of marine crustaceans. The surrounding limestone is etched to give an organic natural stone contrast to the polished sculpture.
The shape, reminiscent of the African Ashanti tribal shield creates a strikingly modern statement. Orthoceras is also referred to as the Orthoceratites and is of the Mollusca phylum, the class of Cephalopoda now found fossilised in the limestone's outcropping in the Western Sahara of North Africa. The Devonian fossilised limestone became a marble over time, dating back to the Palaeozoic era, Devonian period 390 to 380 million years ago.
