Stratigraphy
| Geological group: | Rancocas | Formation: | Hornerstown | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Hornerstown Marl of the Rancocas Gp.

AGE: Hornerstown Marl was Eocene, according to Miller (1947; Danian, according to more recent sources (e.g. Gallagher, 2002), but also includes the upper Maastrichtian at its base (particularly the basal shell bed). STRATIGRAPHIC POSITION: From unknown position within section. | |||||
