Taxonomic list
•Sr isotope date of 2.08 +/- 0.56 Ma: Jones et al. 1995
•contrary to MacFadden 1995, above evidence could place this not only in C1r.1r but also in C2r or C2r.1r; mammal biochronology is compatible with either of the former two
•date could be narrowed to C1r.1r, following MacFadden, by assuming that 1) Leisey 1A and 3A are in the same chron, and 2) the Sr dates are reliable despite the 0.75 Ma discrepancy between them; I find these assumptions to be mutually contradictory
•there are "over 15,000" vertebrate specimens, "the majority of which are from Leisey 1A" (Morgan and Hulbert 1995); 15.3% of specimens in a test square were mammalian (Pratt and Hulbert 1995), suggesting that about 2300 mammalian specimens come from this site
•from Leisey Shell Pit, exact locality unknown: Eremotherium eomigrans De Iulis and Cartelle 1999
•"Panthera cf. onca" is omitted by Berta 1995
•Nerodia sp. and cf. Coluber sp. are listed by Hulbert and Morgan, but are from other Leisey collections according to Meylan 1995
•only the most common molluscs are listed and genus names of other marine invertebrates are not given
