Description
This listing features a magnificent 8-inch Barremites dificilils fossil ammonite, originating from the Lower Barremian Stage of the Early Cretaceous Period, approximately 129 to 125 million years ago. This beautifully preserved specimen was found near Sisteron, France, a region famed for its marine Cretaceous fossil beds. It comes from the notable Alice Purnell Collection, ensuring documented provenance and top-tier fossil curation.
Barremites dificilils belongs to the family Desmoceratidae and is characterised by its moderately involute shell, gently curved ribs, and rounded venter. These traits indicate it was a free-swimming, nektonic marine cephalopod that thrived in the warm epicontinental seas of the Barremian.
This large specimen displays excellent preservation with defined ribbing and classic ammonite coiling, offering both scientific value and visual appeal. A premium piece for any serious collector or educational institution.
Geological Context: The Lower Barremian is part of the Lower Cretaceous, a time of significant marine transgressions and evolutionary diversification. The fossil-bearing beds around Sisteron, in southeastern France, are part of a sedimentary sequence of marls and limestones that offer a rich window into Cretaceous marine ecosystems. Ammonites from this formation serve as important biostratigraphic markers for correlating rock layers across Europe.
