Taxonomic list

• questionable records: type of "Blastomeryx" marshi collected by Marsh from within 25 miles (!) of Quarry F; type of Nothocyon latidens multicuspis not mentioned by Lull Parablastomeryx (Pseudoblastomeryx) marsa Frick 1937: type, "1 mile west of Aletomeryx Quarry" in Cherry County specimen of "Protohippus placidus or niobrarensis" was apparently mislabelled as from Quarry F
