Description
Offered for sale is a beautifully preserved fossil ammonite specimen of Graphoceras decorum, collected from the Concavum Zone of the Bajocian Stage (Middle Jurassic) at Bradford Abbas, Dorset, United Kingdom.
Graphoceras is a genus of extinct ammonites in the subclass Ammonoidea, known for their distinct ribbing, compressed whorls, and involute shell coiling. These cephalopods thrived during the Middle Jurassic around 170 million years ago, inhabiting shallow marine environments. They are key biostratigraphic markers for dating and correlating layers of Jurassic rock.
This exceptional fossil originates from the Concavum Zone, a stratigraphically significant unit within the Bajocian. The rocks here are part of the classic fossil-rich sequences of Southern England, offering insight into the rich biodiversity of ancient Jurassic seas.
This piece is part of the prestigious Alice Purnell Collection, known for its high-quality fossil specimens curated for both scientific value and aesthetic presentation. It has been meticulously prepared to highlight the intricate shell detail and is an outstanding example of this uncommon species.
