Prionocyclus germari (Reuss, 1845), a Late Turonian marker fossil from the Bagh Beds of central India

A specimen of the Late Turonian marker ammonite Prionocyclus germari (Reuss, 1845) is recorded from the upper Nodular Limestone of the Bagh Beds sequence of the Hatni River section near Kukshi, Madhya Pradesh Province, India. A reappraisal of previous ammonite and inoceramid records from the sequence shows that these are all compatible with a Late Turonian date for the upper Nodular Limestone. The higher parts of the Bagh Beds are thus securely dated as Late Turonian to Coniacian on ammonite and inoceramid evidence.
