The Blisworth Limestone is variable both in thickness and in character. It is not oolitic and tends to weather grey such as the matrix you see below. The oyster Praeexogyra hebridica is abundant with some nice examples showing here.
When I found this particular tooth apart from the root missing it would appear to be complete.
Would anyone know what part of the Hybodonts dentition this tooth would be from.
