Where: Oklahoma (34.0° N, 97.0° W: paleocoordinates 22.5° S, 73.8° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Pooleville Member (Bromide Formation), Blackriveran (457.3 - 449.6 Ma)

• Pooleville Echinoderm Zone from the upper half of the Pooleville Member.

Environment/lithology: deep subtidal ramp; limestone and gray, calcareous shale

• Medium to deep. below wave base. Environments from J. Sprinkle and M. W. Longman. 1982. Echinoderm paleoecology.

• "[M[ainly biomicrite and microspar limestone, interbedded with greenish-gray calcareous shale along the axis of the aulacogen. The type section in the southwestern Arbuckles is 71 m thick, with much greenish-gray calcareous shale, and probably represents an area close to the Pooleville depocenter. In most of the Arbuckle Mountains, the upper 5 m of Pooleville is a massive burrowed micrite or calcilutite of the intertidal facies. In the Criner Hills, the Pooleville is about 40 m thick and is mainly a thin-bedded to medium-bedded mudstone or microspar limestone, deposited along the southern margin of the aulacogen. In the northeastern adn northern Arbuckles, the Pooleville is less than 21 m thick, with some birdseye micrite in the upper part." Lithology from R, O. Fay and A. A. Graffman. 1982.
