Where: Holt County, Missouri (40.0° N, 95.1° W: paleocoordinates 1.4° S, 26.7° W)
• outcrop-level geographic resolution
When: Calhoun Member (Deer Creek Formation), Virgilian (303.4 - 298.9 Ma)
• converted feet to meters.
• bed-level stratigraphic resolution
Environment/lithology: shale and limestone
•The sandy interval, directly overlying the lower shale interval, ranges in lithology from sandy shale to silty sandstone. This interval is medium light gray with flaser or lenticular bedding, and is sparsely fossiliferous containing plant fragments (stems and pinnules), Lingula, and scattered bivalves. The sandy interval in two cores (KGS #3 Lyke, and KGS #1 Lyke) is fossiliferous in a thin bed which ranges in thickness from 0.5 ft. (0.15 m.) to 2.0 ft. (0.61 m.). This fossiliferous zone contains large bivalves, brachiopods, gastropods, and plant fragments. The sandy interval ranges in thickness from 14.0 ft. (4.27 m.) to 28.0 ft. (8.53 m.).
