Up for sale is a RARE skull +neck vertebrae of prehistoric wolf Canis teilhardi (carnivorous mammal) from early Pleistocene of Linxia basin, Gansu, China! Canis teilhardi is an early Pleistocene canid first described from the rich fossil assemblages of the Longdan locality in Gansu Province, northwestern China. Morphologically, it represents a medium-sized, early member of the genus Canis, displaying a combination of primitive and derived traits characteristic of transitional wolves emerging during the early Pleistocene. Its cranio-dental anatomy—including a relatively slender snout, moderate robusticity of the mandible, and dentition adapted for a generalized carnivorous diet—positions C. teilhardi among the evolving “wolf-like” canids that were diversifying across Eurasia during the Gelasian. The species is significant for understanding the early radiation of Canis in eastern Asia, a region increasingly recognized as a major center of canid diversification during the late Neogene.
