Norman (Permian of the United States)

Also known as Amos Moses estate

Where: Cleveland County, Oklahoma (35.2° N, 97.4° W: paleocoordinates 2.8° N, 26.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Fairmont Shale Member (Hennessey Formation), Kungurian (279.3 - 272.3 Ma)

• bed 5 of general section of Olson (1967, Oklahoma Geol. Surv. Circ. 74), about 70 feet above the base of Hennessey Fm. Haglund (1977 J. Paleont. 51(5)) additionally states that the locality is in the "Fairmont Shale" of the Hennessey Fm. Haglund (1977) also states, that these beds are equivalents of the Choza Fm. of the Clear Fork Group of Texas. The base and top of the Clear Fork Group are both within the Kungurian: see Wardlaw 2005 (Permophiles) for the base, and DiMichele et al. 2001 (J Paleont) for the top. Original chronostratigraphic entry >>Leonardian<< is replaced by >>Kungurian<< (TL).

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; red shale and sandy shale

• "[...] the quarry [...] lies in the upper part of a thick bed of red shale. Not far above the upper level of the bone producing layer are coarser sandy shales. These, of course, bear no relationship to the deposition of the sediments of the quarry. The sediment of the quarry basically is a red-shale. Structureless red clay-shale makes up at least 80 per cent of the total. Irregularly disposed patches of lighter colored, somewhat sandier shale occur and in places small patches of pebbles, 1 to 5 mm. in diameter, are present. The most distinctive sediment is a greenish-brown, brecciated, slightly sandy shale. It shows no regular disposition either vertically or horizontally."

Taxonomic list

• "individual bones, partial skeletons, skulls, jaws and occasional teeth of lungfish, scales of palaeoniscoids, small amphibians and reptiles"

•"To date the excavation has covered an area of about 350 square feet and approximately 1,500 cubic feet of sediment have been examined for fossils. Although the specimens are somewhat clumped in occurrence, it can be estimated fairly that they average about three per cubic foot. Thus the total number of specimens in the materials studied ranges in the neighborhood of 4,500. Of these, of course, only a small part, several hundred, has been collected. Much of the material is very fragmentary and with a few exceptions only articulated specimens, skulls, jaws and well preserved single bones were kept. Over one-half of all specimens found pertain to Lysorophus, usually consisting of vertebrae and ribs. In general, remains of this amphibian were collected only when preservation was exceptionally good, much of an individual was present, or skulls were found, either alone or associated with skeletons [!]."
