Collection methods and comments
| Collection excludes: | some genera |
| Taxonomic list comments: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 possibly relevant record: Diacodon alticuspis Novacek 1982: "Ojo Almagre Quarry" "Bathmodon sulcidens" Simpson 1951: species not mentioned by Uhen and Gingerich 1995 | |
