Material: PDYV 2522.2, a fragmented upper canine, from Locality 8603, Zhupeng; YMV335, a broken upper canine, from Locality 8603, Zhupeng; PDYV2524.1, an isolated P4; RV2006023, an isolated p4; RV2006047 (PDYV328), an isolated p4, from Locality 9803, Xiaohe; PDYV2522.3, an isolated p4, from Locality 8704, Xiaohe; RV2006049, an isolated m1 (PDYV316), from Locality9803, Xiaohe; PDYV2525, one complete and one broken m1, from Locality 8801, Xiaohe.

Description

The fragmented upper canine PDYV2522.2 has a clear ridge on its anterior and posterior sides, but no serration is present. The broken canine YMV335 is similar. Even though partially reconstructed, it seems that the crown of the canine is high. The P4 PDYV2524.1 is elongated and slender. There is no preparastyle. The protocone is more anteriorly located, behind the level of the parastyle/paracone notch.

The three p4s have similar morphology. There is no buccal or lingual concavity. The anterior and posterior accessory cuspids are similar in size, and the posterior cingulid is only slightly cusp-like. The two m1s are elongated, with a talonid not distinguished from the protoconid. The teeth are trapezium-shaped, with a nearly straight buccal border. The lingual border is concave between the paraconid and protoconid. The widest part of the tooth lies at the level between the paraconid and the protoconid. The broken m1 seems to be wider, and has a smoother buccal border, but no further information can be discussed.
