Where: Osage County, Oklahoma (37.0° N, 96.3° W: paleocoordinates 3.4° S, 29.1° W)
• coordinate estimated from map
When: Leavenworth Limestone Member (Oread Limestone Formation), Virgilian (303.7 - 298.9 Ma)
• Leavenworth Limestone Member of the Oread Limestone is the "middle-limestone" of the Oread Megacyclothem (Pennsylvanian, Virgilian); stratigraphic and faunal evidence suggests that the Salem School Member of northcentral Texas is time correlative with the Leavenworth Limestone
•stone
•Thickness 0.9 feet
Environment/lithology: platform or shelf-margin reef; limestone
•Leavenworth limestone is dark bluish-gray, fine-grained, dense, very hard, vertically jointed, moderately fossiliferous; in most localities is occurs as one prominent bed ranging in thickness from slightly under 1 foot to a max. of 3 feet; skeletal mud occurs at 27 (of 32) localities and is the dominent LL facies
•as the LL is traced further southward (in OK) the fusulinid-rich portion dominates more and more of the unit, until at Locality 2 the LL is practically a fusulinid coquina with a thin (2") mud base
Size classes: mesofossils, microfossils
• in addition to the algae: coarse borings (algal?)
•silicified sponge spicules are found at localities 16, 21, 23, 27, 28, 29; sponge spicules were observed across the outcrop belt though
•fecal pellets are found but not present at localities 1,2,4,16,17,19,22, 24A, 25, 26, 28, 29
