• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Greggs Landing Marl Member (Tuscahoma Formation), Thanetian (59.2 - 56.0 Ma)

• The Greggs Landing Marl Member, about 6 feet thick, exposed near the bottom of a high bluff, yields numerous well preserved mollusks and a colonial coral. The Bells Landing Marl Member is exposed near the top of the steep bluff 27 feet higher than the top of the Greggs Landing Marl Member and contains the characteristic large spheroidal concretions and large Ostrea sinuosa, Venericardia aposmithii and Turritella postmortoni and a few other characteristic fossils which fall down the bluff and are mixed with the Greggs Landing fossils.
