摘要

(1) 背景:尽管弗里施(Frisch,1775)狐属(Vulpes Frisch,1775)是现存犬科中种类最多的,但其化石记录却非常稀少,尤其是在亚洲上新世。这种记录的稀缺性使重建这些类群与现存物种的进化情景变得更加复杂。早更新世的情况似乎略有改变,当时记录了两个物种:欧洲的 Vulpes alopecoides(Del Campana,1913 年)和亚洲的 Vulpes chikushanensis(Young,1930 年)。与前者的广泛记录不同,中国的筑山狐(Vulpes chikushanensis)的遗存很零散,该分类群的有效性也受到质疑。(2)研究方法:将甘肃庆阳八家嘴早更新世遗址(1.8-1.2Ma)的标本与大量的Vulpes属动物标本进行对比研究,以确定Vulpes属动物在中国的分布情况。(3) 结果:从形态学和形态计量学上看,巴家嘴的标本与中国其他早更新世地点的狐狸标本相吻合,如甘肃陇丹和甘肃庆阳的狐狸标本;从形态学和形态计量学上看,巴家嘴的狐狸标本与中国其他早更新世地点的狐狸标本相吻合,如甘肃庆阳的狐狸标本、(4)结论:对亚洲狐化石记录的修订对于我们理解和重建早更新世晚期(1.8-0.8Ma)食肉动物的演化过程至关重要。巴家嘴的狐狸化石虽然残缺不全,但为我们了解筑山狐(V. chikushanensis)增添了宝贵的资料,筑山狐可能与现存的科萨克狐(Vulpes corsac)(林奈,1768 年)有密切的亲缘关系。

The Fox from Bajiazui (Qingyang, Central China) and an Update on Early Pleistocene Foxes from China
(1) Background: despite the fact that nowadays the genus Vulpes Frisch, 1775, is the most diverse among extant Canidae, its fossil record is utterly scarce, especially in the Asian Pliocene. The sparse nature of this record further complicates the reconstruction of the evolutionary scenario to fit these taxa with extant species. The situation seems to change slightly in the Early Pleistocene when two species are recorded: Vulpes alopecoides (Del Campana, 1913) in Europe and Vulpes chikushanensis, Young, 1930, in Asian localities. Unlike the former, which has an extensive record, the remains of the Chinese V. chikushanensis are sporadic and the validity of the taxon has also been questioned. (2) Methods: the study of the specimens from the Early Pleistocene site of Bajiazui (1.8–1.2 Ma, Qingyang, Gansu) in comparison to an extensive sample of Vulpes spp. The Pliocene–Early Pleistocene is relevant for the delimitation of fossil foxes variability; (3) Results: morphologically and morphometrically, the specimens of Bajiazui fit with the specimens of V. chikushanensis from other Chinese localities of the Early Pleistocene, e.g., Longdan (Gansu) and Huiyu (Fangshang), highlighting some difference with the latest Early Pleistocene forms of Jigushan fox; (4) Conclusions: the revision of the Asian fossil record of Vulpes is crucial in our attempt to understand and reconstruct the evolution of carnivoran guild during the late Early Pleistocene (1.8–0.8 Ma). The fox remains from Bajiazui, although fragmentary, add a valuable piece to our knowledge of V. chikushanensis, a species possibly strongly related to the extant Vulpes corsac (Linnaeus, 1768).
