Partin Felis sp.1 Zong, 1997: 86 .

Material: PDYV2524.2, an isolated P4, from Locality 8801, Xiaohe.

Description

The isolate P4 PDYV2524.2 is smaller but more robust than that of Longchuansmilus xingyongi and PDYV2524.1. There is no distinct buccal concavity. The parastyle is small, with a tiny and indistinct preparastyle located slightly lingual to the parastyle. The protocone is located at the level between the parastyle and the paracone. It is only slightly reduced in size, larger than the corresponding one in Longchuansmilus xingyongi .

SUBFAMILY FELINAE FISCHER, 1817

FELINAE GEN. & SP. INDET.

( FIG. 3 ; TABLE 1)

Material: RV2006020 (PDYV929), an isolated upper canine, from Locality 9904, Leilao; RV2006021 (PDYV375), an isolated lower canine, from Locality 9904, Leilao; RV2006022 (PDYV936), an isolated p4, from Locality 9803, Xiaohe; no catalogue number, an isolated p4; PDYV2575, an isolated m1; PDYV2526, an isolated m1, from Locality 9001, Xiaohe.

Description

Both upper and lower canines are conical, and both have a distinct buccal groove, but no lingual groove. The two p4s were similar to those of aff. Yoshi sp. but considerably smaller. The dental crown is slightly higher and the tooth is more slender. The accessory cuspids are generally smaller. The posterior cingulid is distinctly lower and not cusplike. The m1 is stouter. The talonid is smaller and also not distinguished from the protoconid. The buccal border is smoothly convex.
