Anacacho (collective) (Cretaceous of the United States)

Where: Texas (29.2° N, 100.3° W: paleocoordinates 35.0° N, 73.7° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Bostrychoceras polyplocum ammonoid zone, Anacacho Limestone Formation, Middle Campanian (83.5 - 70.6 Ma)

• AGE: Late Campanian, on the basis of ammonoid biostratigraphy; Bostrychoceras polyplocum zone; was originally entered as Middle Campanian. Comment by J. Sessa: Swezey and Sullivan (2004) correlate this bed to the Baculites maclearni zone, which is middle Campanian in Gradstein et al., 2004. Also, Bostrychoceras polyplocum zone spans almost the entire middle Campanian and part of the upper Campanian, thus I have changed the interval back to middle Campanian.

Environment/lithology: marine; carbonate

Size class: mesofossils
