A section of jaw fragment with teeth from the Phcnodonidae Gyrodus.
The Gyrodus was a very deep-bodied fish and with a circular outline. Its dorsal and anal fins were symmetrically placed with a deeply notched tail fin. The Gyrodus, known as boney fish, had deep, rectangular scales which covered the body surface and densely packed, rounded teeth, suggesting it may have had a diet of coral or other hard- bodied prey.

Nice preserved piece.
