Station 19, Foggyhead Creek, Navarro Co., TX (Paleocene of the United States)

Where: Navarro County, Texas (32.1° N, 96.2° W: paleocoordinates 36.3° N, 78.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Kerens Member (Wills Point Formation), Selandian (61.6 - 59.2 Ma)

• The outcrops 12 to 18 occur either as too isolated or in such badly faulted areas, that it is impossible to arrange them stratigraphically with any degree of certainty, but it is certain that they lie within the Mexia clay member and probably in its lower part.

•Kerens Member is Middle Paleocene = Selandian according to: Armstrong, A., Nyborg, T., Bishop, G.A., Morales, À.O. and Vega, F.J., 2009. Decapod crustaceans from the Paleocene of Central Texas, USA. Revista Mexicana de Ciencias Geológicas, 26(3), pp.745-763.

Environment/lithology: marginal marine; unlithified, micaceous, silty claystone

• These somewhat fossiliferous, silty and micaceous clays carry the foraminiferal fauna typical of the uppermost strata of the Wills Point formation...

Size class: microfossils

• These somewhat fossiliferous, silty and micaceous clays carry the foraminiferal fauna typical of the uppermost strata of the Wills Point formation, characterized especially by Ammobaculites midwayensis Plummer and A. expansus Plummer. Ostracodes are frequent, and the holotype of Monoceratina rossae n. sp. has been taken from this material
