Where: Durham County, North Carolina (35.9° N, 78.9° W: paleocoordinates 7.6° N, 21.3° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Carnian to Carnian (237.0 - 208.5 Ma)
• Late Carnian or early Norian.
•All fossils found together in one bed within the "Lithofacies Association II". "Huber et al. (1993) regarded Lithofacies Association II as the stratigraphic equivalent of the lower Sanford Formation in the neighboring Sanford sub-basin. Based on the occurrence of the palaeonisciform fish Turseodus, Olsen et al. (1989) correlated Lithofacies Association II of the Deep River basin with the Lockatong Formation of the Newark basin and the 'upper member' of the Cow Branch Formation of the Dan River basin and thus regarded its age as late Carnian. Lucas et al. (1998) used the presence of the stagonolepidid Stegomus arcuatus (which they referred to Aetosaurus) to argue for an early to middle Norian age for what they termed the 'Neshanician land-vertebrate faunachron,' which includes the vertebrate assemblage from Lithofacies Association II...The biostratigraphic evidence cannot definitely resolve the question whether the tetrapod assemblage from Lithofacies Association II is late Carnian or early Norian in age."
