Stovall's Pit 6, Kenton (OMNH V95) (Jurassic to of the United States)

Also known as OK-3, WPA

Where: Cimarron County, Oklahoma (36.9° N, 103.0° W: paleocoordinates 32.3° N, 50.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Kenton Member (Morrison Formation), Late/Upper Kimmeridgian to Late/Upper Kimmeridgian (155.7 - 145.0 Ma)

• in beds equivalent to Brushy Basin Mbr.; upper middle part of formation; 38 m above the J5 unconformity

• bed-level stratigraphic resolution

• poorly drained floodplain
• "the productive horizon at Quarry 6 is in an illitic mudstone between several thin sandstone beds. Underlying the quarry is a 50-cm-thick sandstone bed. Overlying the quarry mudstone is a 50-cm-thick sandstone bed followed by a green 40-cm-thick mudstone bed. Capping the 40-cm-thick mudstone bed is a second 60-cm- thick sandstone bed."
