751E87FBFFC89710F62387EA32C2F8AE.taxon	materials_examined	Material: RV 2006048 (PDYV 1222), an isolated p 4, from Locality 9903, Leilao. Description: This p 4 has a large size. The tooth is slightly widened posteriorly. The anterior accessory cuspid is distinctly larger than the posterior one. There is a tiny additional cuspid before the anterior accessory cuspid. The posterior cingulid is cusp-like.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.

751E87FBFFC89710F6EF813B32C3FAB5.taxon	description	Remarks: Most recent authors use Homotheriini to refer to the scimitar-toothed cat, including, e. g. Amphimachairodus, Homotherium, Lokotunjailurus Werdelin, 2003 Xenosmilus Martin et al., 2000, and sometimes Machairodus Kaup, 1833 (Turner & Antón, 1997; Werdelin et al., 2010). When Machairodus is included in this tribe, which is adopted here, the correct tribe name should then be Machairodontini Gill, 1872. In addition to the abovementioned genera, and the new genus described below, some smaller-sized species, e. g. derived species of Paramachaerodus like P. maximiliani McKenna & Bell, 1997, have a potential affinity to this tribe.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.

751E87FBFFC99715F5A187C9358EFE1A.taxon	diagnosis	Diagnosis: Medium-sized machairodontine of large jaguar size. Forehead not distinctly wider than rostrum, but frontal sinus well developed. Incisor moderate in size, not procumbent; canine narrow, with clear serration; no P 2; P 3 reduced in size, with distinct anterior accessory cusp; P 4 with distinct preparastyle and moderately reduced protocone. Differential diagnosis: Differs from Machairodus by its smaller size, I 2 with V-shaped posterior accessory cusp, more reduced P 3 and P 4 protocones; differs from Amphimachairodus by its distinctly smaller size, smaller and less procumbent incisor, more reduced P 3; differs from Lokotunjailurus by smaller size, absence of P 2, slightly larger P 3, less elongated P 4 with larger protocone; differs from Homotherium / Xenosmilus by its smaller size, distinctly smaller and much less procumbent incisor, larger P 3 and P 4 protocones, stronger P 4 parastyle; differs from Paramachaerodus and Metailurus by its larger size, presence of distinct canine serration, smaller P 3 and distinctly stronger P 4 preparastyle and smaller protocone.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.

751E87FBFFC99715F5A187C9358EFE1A.taxon	description	Description The cranium is nearly complete, but unfortunately laterally crushed and somewhat deformed. The zygomatic arch is missing and poorly reconstructed by plaster. The posterior part of the sagittal crest is broken (so the total length of the skull cannot be established) and the basicranial part is poorly preserved. The cranium seems to have an angle in its dorsal profile, at the level of the anterior part of the braincase. In dorsal view, it can be seen that the rostrum has no postcanine constriction. No information on nasal shape and its boundary can be extracted due to poor preservation. The postorbital process of the frontal is small but distinct. The forehead is not widened, only slightly wider than the rostrum. It can be seen that the frontal sinus is well developed, expanding the postorbital constriction. The temporal ridges from both sides unite with the sagittal crest at the level between the postorbital constriction and the braincase. The sagittal crest is well developed. In lateral view, the mastoid process is largely broken, but judging from the remaining part, the mastoid process is significantly enlarged. There is nearly no trait that can be seen in the ventral view due to breakage. The bony choana extends significantly posterior to the tooth row. The glenoid fossa does not seem to elevate above the basicranial region. The incisor row is only slightly procumbent. The medial incisor is slightly enlarged. Judging from the facet, the posterior accessory cusps are V-shaped and ridge-like. The I 3 is slightly enlarged, without an accessory cusp. The canine is narrow, with clear serration seen in the posterior side. (The situation in the anterior side is invisible) There is no P 2. The P 3 is reduced in size. It has a distinct anterior accessory cusp, located slightly medial to the main cusp. The lingual part of the tooth cannot be clearly seen due to poor preservation. The buccal border is concave between the main cusp and the posterior cingulum. The P 4 has a narrow blade. The parastyle part is clearly elongated. Even though the tooth is heavily worn, it can be seen that the preparastyle is large and seems to be in line with the parastyle. The metacone is also elongated. The protocone is reduced in size. It is located at the level between the parastyle and paracone. There were two isolated canine fragments and one P 3 that most likely belongs to this species. Both canine fragments have clear serrations on their edges. The P 3 is in good preservation; it is nearly the same size as that of YMV 87001 and has a similar tooth outline. The anterior accessory cusp is more lingually located than in the case of YMV 87001. The postero-lingual convexity is distinct. The posterior cingulum has a distinct cusp. A single premolar RV 2006046, which seems to be a p 3, has a unique morphology. Weak serration can be seen in the tooth, a typical trait of Machairodontini, and seems to be too small for Amphimachairodus, which we tentatively assign to Longchuansmilus.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.

751E87FBFFCD9715F69E806332B7FC47.taxon	description	Remarks: Our concept of Metailurini is largely similar to that used by Turner & Antón (1997) and Werdelin et al. (2010), only that we found most species of Paramachaerodus similar to Metailurus, and these two genera are likely to be closely related. Paramachaerodus does not show a closer affinity to Smilodontini than Metailurus does. The two derived species of Paramachaerodus have serrated canines and V-shaped incisors, and are unlikely to be ancestral to Smilodontini. Their positions are in need of further investigation.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.

751E87FBFFC2971AF5D680C83342F89C.taxon	materials_examined	Material: PDYV 2524.2, an isolated P 4, from Locality 8801, Xiaohe. Description The isolate P 4 PDYV 2524.2 is smaller but more robust than that of Longchuansmilus xingyongi and PDYV 2524.1. 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.

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 m 1 is stouter. The talonid is smaller and also not distinguished from the protoconid. The buccal border is smoothly convex.	en	Jiangzuo, Qigao, Li, Shijie, Fu, Jiao, Duan, Shiqi Wang Xueping Ji Mei, Che, Decai (2022): Fossil Felidae (Carnivora: Mammalia) from the Yuanmou hominid site, southern China (Late Miocene) and its significance in the living environment of the fossil ape.
