The mandible has two mental foramina, a large one positioned below the posterior root of p2 and the anterior root of p3 and a small one positioned below the roots of p4. It contains the alveoli for three anteriorly projecting incisors. The alveolus for i3 is followed by a large alveolus for the canine and by two small alveoli. No small uniradicular teeth fitting these alveoli were found and the position and size of these alveoli seems to indicate that p1 is absent and p2 is double−rooted and moderately smaller than p3. The absence of p1 would be unique among nyctitheriids; lacking further confirmation, we prefer to handle this feature with a certain care but at least it is clear that

has an anteriorly projecting paraconid that is crestiform and fused with the paracristid. The protoconid is slightly larger and higher than the metaconid. The anterolabial cingulum is well−developed and can continue along the base of the protoconid. The hypoconulid is slightly closer to the entoconid than to the hypoconid and is the smallest talonid cusp, while the hypoconid and entoconid are subequal in height. The ridge between hypoconid and hypoconulid often exhibits considerable wear and in worn specimens the hypoconid may be the lowest of the talonid cusps. The oblique crest joins the trigonid low on the trigonid wall.

The ectocingulum bears a small parastyle; the metastylar crest and ectoflexus are moderately developed, but stylar cusps are absent. The trigon is transversely elongated, with two subequal conules, well−developed conule crests, and pre− and postprotocrista. The precingulum is small but always present; the postcingulum is relatively small with a hypocone and a remarkably straight posterior border.
