Navesink may still be considered Cretaceous (not certain), but I am pretty certain Hornerstown was found to be Early Paleocene (Danian).

Dale Russell, in _A Check List of North American Marine Cretaceous

age for the Navesink and latest Maastrichtian for the Hornerstown. Both have
dinosaurs and mosasaurs. DV
