This is a rare PHRAGMACONE - TORCYBELUS fossil from the Lower Sinemurian stage of the Early Jurassic period, discovered in Hornsea near Cowden, United Kingdom. Belemnites were extinct marine cephalopods related to modern squid and cuttlefish. Unlike ammonites, they had an internal shell structure known as a phragmocone, which functioned as a buoyancy chamber. These fossils are far less common than the solid belemnite guards, making them particularly desirable for collectors and researchers.
