Taxonomic list
• records from Simpson 1951 pertain to a list reproduced from Cope's diaries; most of Cope's collection is from the south fork of the arroyo, i.e., near AMNH Quarry 51
vicinity of multiple localities: see Lucas et al. 1981
Williamson and Lucas 1992a report Meniscotherium tapiacitum from NMMNH Loc. 241, which is on the divide between Almagre Arroyo and Arroyo Blanco
