[Gardner & DeMar: Appendix 7] 1
Appendix 7. Sources for taxonomic identifications of latest Maastrichtian (Lancian NALMA) and/or earliest Palaeocene (Puercan NALMA) lissamphibians listed in Table 7 for the Bug Creek Anthills locality, Hell Creek Formation, McCone County, northeastern Montana, USA. This locality is plotted as “BCA” on the Lancian locality map (Fig. 6). This is not a comprehensive listing of all reported specimens; for example, it does not include the MCZ bulk numbered lots listed by Estes et al. (1969) for salamanders from Bug Creek Anthills.
Allocaudata / Albanerpetontidae / Albanerpeton nexuosum: Dentary (UALVP 40035) reported by Gardner (2000a).
Allocaudata / Albanerpetontidae indet.: Dentaries (UALVP 43841–43843) reported by Gardner (2000a).
Urodela / Scapherpetontidae / Scapherpeton tectum: Atlantes (UALVP 40092–40104: Gardner 2000b, fig. 11-8A–R) and trunk vertebrae (UALVP 40109: Gardner 2000b, fig. 11-8RR–TT) described and figured by Gardner (2000b). Gardner (2000b, fig. 11-8M–R) described and figured a nearly complete atlas (UALVP 40104) missing only the right postzygapophysis. A second nearly complete atlas (MOR 6101) recently identified by DeMar and Wilson (unpubl. obs.) is distinctly different in its neural arch, crest, and spine morphologies from UALVP 40104. Pending further study of that pair of atlantes, both are retained here in Scapherpeton tectum.

Additional atlas (MCZ 3637) and trunk vertebrae (MCZ 3629–3632, 3634, 3636) reported by Estes (1969c). Atlantes (UALVP 43813–43816: Gardner 2003b, fig. 4D–N), trunk vertebrae (UALVP 43818, 43830, 43831, 43839, 43835; MCZ 3929: Gardner 2003b, fig. 5C–L and Q–U), and caudal vertebra (UALVP 43840: Gardner 2003b, fig. 5V–X) described and figured by Gardner (2003b).

Note that MCZ 3627, 3628, 3633, and 3635 originally reported by Estes (1969c) as vertebrae of Proamphiuma cretacea are from other caudates (Gardner 2003b).

Anura / Palaeobatrachidae / Palaeobatrachus? occidentalis: Fused atlas + first trunk vertebra (UALVP 40163) described and figured by Gardner (2008, fig. 13.1E–H). This identification has been questioned (Roček this volume; Wuttke et al. 2012), but pending further study and comparison of the relevant specimen it is provisionally retained here.

Unfigured ilium (MCZ 3624) listed by Estes (1969b).
Anura / Family incertae sedis / cf. Eopelobates sp.: Right frontoparietal (UALVP 40164) described and figured by Gardner (2008, fig. 13.3F, G). Other specimens listed by Estes et al. (1969, pp. 14–15) include fragmentary maxillae, a squamosal, and three ilia.
Anura indet.: Distal ends of humeri (MCZ 3654a, 3654b: Estes et al. 1969, fig. 3a–c and 3d–f, respectively). Other indeterminate anuran specimens (no catalogue number given) reported by Estes et al. (1969, pp. 15–16) as “other frog remains” include two maxillary fragments lacking external ornamentation, humeri, a procoelous vertebra, an ilium, postdentary jaw fragments, two fragmentary radioulna, and a tibiofibula.

(1969, p. 14), referred to Palaeobatrachus occidentalis by Estes and Sanchíz (1982), and excluded from the latter species by Gardner (2008, p. 222).
