Where: Limestone County, Texas (31.7° N, 96.5° W: paleocoordinates 36.3° N, 77.2° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Mexia Clay Member (Wills Point Formation), Danian to Danian (66.0 - 59.2 Ma)
• The very compact, gray, fossiliferous clays carrying numerous small corals lies within the Mexia clay member of the Wills Point formation and about 35 feet above the top ledge of the Tehuacana limestone. A few yards north and west of this outcrop along the creek, lignitic Wilcox strata are faulted down against these lower strata of the Wills Point formation.
•Mexia Clay Member is Early-Middle Paleocene = Danian-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, gray claystone
Size class: microfossils
• fossiliferous clays carrying numerous small corals
•This is the type locality for Cytherella tumidosa n. sp., C. excavata n. sp., C. symmetrica n. sp., Argilloecia faba n. sp., Paracypris perapiculata n. sp., Bairdia suborbiculata n. sp., Brachycythere formosa n. sp., Cythereis sculptilis n. sp., C. lemnicata n. sp., and Eucythere midwayensis n. sp. Plesiotypes of Cythereis spiniferrima Jones and Sherborn and C. prestwichiana Jones and Sherborn have been figured from these clays.
