“…Its phylogenetic position within the Canidae is relatively controversial but may be relatively basal (Bardeleben et al 2005;Wang and Tedford 2008). Several extinct species of the genus have been described, including N. donnezani (Europe), N. tingi (China; thought to have existed from the Miocene to Pliocene), N. megamastoides (Europe), N. terblanchei (Africa; although its taxonomic validity is questioned by Reynolds 2012), N. vulpinus (Europe) from the Pliocene and N. sinensis (China) from the Pliocene to the early Pleistocene (Kauhala and Saeki 2004;Monguillon et al 2004;Wang and Tedford 2008). However, N. procyonoides is the only living species (Saeki 2009).…”

Asahara, M. and Takai, M. 2017. Estimation of diet in extinct raccoon dog species by the molar ratio method. -Acta Zoologica (Stockholm) 98: 292-299.Estimation of the dietary habits of extinct species using morphological traits has been attempted in numerous studies; however, previous methods have encountered several difficulties, such as requiring specialized equipment. In this study, we describe an easy quantitative method for estimating the dietary habits, and apply it to extinct raccoon dogs (Nyctereutes) species (Carnivora, Mammalia). The method is based on the lower molar ratios (M 2 /M 1 size) that reflect the species diet (carnivorous and omnivorous tendencies) in Canidae. Among the species statistically compared, Nyctereutes sinensis showed a lower M 2 /M 1 score similar to that of Nyctereutes procyonoides albus (Hokkaido, Japan), whereas Nyctereutes tingi had a higher M 2 /M 1 score similar to that of Nyctereutes procyonoides viverrinus (Honshu and Kyushu, Japan). These scores suggest that the diets of N. sinensis and N. tingi were similar to those of N. p. albus (relatively carnivorous) and N. p. viverrinus (relatively omnivorous), respectively. Other extinct raccoon dogs also showed varied M 2 /M 1 score, suggesting dietary difference. These results suggest that raccoon dogs underwent dietary transitions or exhibited dietary plasticity during evolution, while their range of diets might have remained the same as those of different populations of extant species Nyctereutes procyonoides.

“…The extant N. procyonoides appears in the Middle Pleistocene deposits of Zhoukoudian (localities 1 and 13). Even though the phylogenetic relationships of late Pliocene Eurasian species of Nyctereutes are still a matter of debate (see Tedford and Qiu, 1991;Monguillon et al, 2004), we deem a closer relation plausible between the extant N. procyonoides and N. sinensis. The occurrence in the Kvabebi sample of Nyctereutes megamastoides, as identified by Vekua (1972), testifies to the wide geographic range expansion of this western European taxon.…”

Abstract.-Unlike the Asian and North American Pliocene record, fossil occurrences of Canidae in Europe (and Africa) are uncommon and fragmentary. The revision of canid material from the late Pliocene site of Kvabebi (eastern Georgia) revealed the contemporaneous occurrence of three different taxa: (1) Nyctereutes megamastoides (a derived species of the Eurasian Pliocene raccoon dog-like canids); (2) Vulpes cf. V. alopecoides (representing the first occurrence of a member of the vulpine taxon V. alopecoides, a species that was the most widespread fox in the early Pleistocene in western Europe); and (3) Eucyon sp. The latter occurrence at Kvabebi completes our knowledge of the late Pliocene evolutionary history of the latest representatives of the genus in Western Europe and Central Asia. Our revision of Kvabebi canids registers a previously undocumented case of established niche partitioning among early Pliocene sympatric Canidae.

“Measure my teeth and you'll know what I ate”: The molar ratio method and an updated interpretation of the diet of Nyctereutes sinensis (Carnivora, Canidae)

The molar ratio method presented by Acta Zoologica (98, 2016, 292) is a valid way to estimate the dietary differences between extant subspecies of the raccoon dog genus, Nyctereutes. Particularly, higher values of the molar ratio implies more omnivous diet than lower ones. With the same technique is possible to infer variations in the diet of extinct species. For the two Plio-Pleistocene fossil species Nyctereutes sinensis and Nyctereutes megamastoides, the authors estimate a more carnivorous diet for the latter in comparison to the former that has much higher values. This fact contrast with the morphological features of these two highly comparable species, often considered as morphotypes of the same species. Thanks to the revision of a large sample of N. sinensis from Chinese localities of the Yushe Basin (Shanxi Province), new scores for this species have been calculated. The results presented here confirms a strong adaptation to an omnivorous diet, as emerged from morphofunctional evidence in recent literature.
