“…On the other hand, canid teeth are much more complex than felid teeth and thus have more homologous features for landmarks. Therefore, Asahara et al (2015) have applied morphological comparisons in combination with geometric morphometric analyses to canine teeth, which is an integrative method that has never been performed on felid teeth. This study, for the first time, demonstrates that an integration of morphological comparisons, linear measurements, and geometric morphometric studies allows species identification of the subfamily of Pantherinae based on teeth.…”

“…Besides, fossil remains of Panthera tigris have also been collected from the Penghu Channel, a N-S striking submarine valley off the west coast of Taiwan ( Fig. 1 ) ( Ho, Qi & Chang, 1997 ; Asahara et al, 2015 ). While both of these studies indicate a rich fossil record of felids in the Middle-Late Pleistocene of Taiwan, the modern Felidae in Taiwan are only featured by two species, including clouded leopard ( Neofelis nebulosa ) and leopard cat ( Prionailurus bengalensis ).…”

Longshia-dong Cave, a limestone cave located in the Kenting area within the Kenting National Park of southern Taiwan, yields numerous terrestrial mammalian fossils. Many of them were not reported in historical literature and are neither present in Taiwan. For instance, no historical literature mentioned leopards inhabited in Taiwan, and thus their existence remained unknown. This study describes three fossil leopard (Panthera pardus) teeth uncovered from Longshia-dong Cave. Two isolated lower premolars and one lower molar, respectively p3, p4 and m1, were discovered in a very small area (11 × 6 cm) and show a series of progressive increase in size. Thus, the three teeth should have been belonging to the same individual from the subfamily of Pantherinae. Traditional linear measurements and two-dimensional geometric morphometric analysis for the occlusal surface outlines were conducted on the fossil teeth and extant pantherines inhabited in Asia such as clouded leopards (Neofelis nebulosa), leopards (Panthera pardus), and tigers (Panthera tigiris). Results show that the fossil teeth are similar both in size and morphology to the teeth of extant leopards, suggesting the assignment of the fossil teeth to leopards. This study, for the first time, reported the presence of leopards in the Late Pleistocene of Taiwan. In addition, the smaller size of the fossil teeth in comparison with Chinese fossil leopards is putatively attributed to insular dwarfism or individual size variability, yet more studies are required.

“…Abundant vertebrate fossils have been dredged up by fishermen, but the stratigraphic data or its geological age remains uncertain. The sea bottom of the Taiwan Strait has yielded marine and terrestrial fossil vertebrates, reflecting the sea‐level change during the Pleistocene, indicating this area includes terrestrial and marine deposits (e.g., Gao, 1982 for Elaphurus ; Tseng & Chang, 2007 for Crocuta ; Shan et al, 2013 for Alligator ; Tsai et al, 2014 for Eschrichtius ; Asahara et al, 2015 for Nyctereutes ; Chang et al, 2015 for Homo ; Tsai & Chang, 2019 for Eubalaena ). The age control of fossils from the sea bottom of Taiwan Strait remains unresolved, and we here also follow Tsai and Chang (2019) that it should be broadly dated Middle to Late Pleistocene (0.78 to 0.01 million years ago).…”

Proper taxonomic identification is critical to our understanding of biodiversity and the underlying evolutionary history. Here we re-examine the cast of the holotype of Chinemys pani, a geoemydid turtle from the Pleistocene of Taiwan; the actual specimen was not curated appropriately after the original publication and was most likely lost. Our results provide substantial evidence to show that Chinemys pani should be identified as Mauremys reevesii. The replica, though not ideal, preserves various morphological features that allow reliable taxonomic identification of Mauremys reevesii, including the presence of three longitudinal keels on the carapace, the second to sixth neural bones anteriorly short-sided, and the lack of a movable plastral hinge. In addition, we also confirm that the original diagnostic features that established the new taxon: Chinemys paniare polymorphic characters of Mauremys reevesii. Our taxonomic revision of a Pleistocene geoemydid turtle from Taiwan confirms the existence of the Pleistocene Mauremys reevesii. More importantly, this study offers new insights into the origin of modern biodiversity in Taiwan and gives a straightforward example of how fossils can be applied to conservation policies.

Southern extension of raccoon dog Nyctereutes procyonoides (Mammalia: Carnivora: Canidae) range in Vietnam with comments on its conservation status in the country

Although the Raccoon dog (Nyctereutes procyonoides) has a wide global distribution, little is known about its population in Vietnam. The species is considered rare in Vietnam and few records have been published since 2004; though it is worth noting that all of these records were wildlife trade observations or anecdotal reports. Here we report Raccoon dogs recorded in the illegal wildlife trade via Facebook monitoring from January to December 2020, rescued animals documented in the same province caught by a hunter in August 2020, and camera trap records of the species detected in Pu Mat National Park in May and July 2021. Our camera trap records represent a southern extension of the known range of this species in Vietnam, and is the rst known instance of the Racoon dogs recorded in-situ by camera traps in the country.
