Fossil lizards are scarce in Jinlin Province, with only two jaws of Middle Eocene Acrodonta. Here the authors report the first scincomorph lizard materials from the early Campanian Nenjiang Formation in Nong’an, Changchun, Jilin Province. Three tooth morphologies of scincomorph lizards represented by fragmentary dentaries are tentatively identified as Scincomorpha. The morphology of the crowns indicates probably the insectivorous and omnivorous diets of these small lizards. It is the first lizard fossils discovered in the Late Cretaceous of Northeast China, extends the known paleogeographic distribution of scincomorph lizards, and provides new information about the terrestrial vertebrate fauna of the Cretaceous Songliao Basin.

Abundant dinosaur remains have been discovered from the Heilongjiang/Amur area for over one hundred years. Among these discoveries, an isolated small theropod tooth recently found from the lower part of the Yuliangzi Formation of Jiayin displays highly distinctive morphological features. It can be identified as a Troodon-morphotype tooth based on mesiodistal constriction at the base of the crown and large, hook-like denticles extending the entire length of both carinae. Previously, Troodon remains were mainly found in North America. Some isolated Troodon teeth were also discovered in Blagoveschensk and Kundur localities on the left bank of the Heilongjiang river. This specimen represents the first occurrence of Troodon-morphotype tooth in Jiayin, Heilongjiang, Northeast China. The presence of this taxon in Jiayin, Blagoveschensk and Kundur localities in the Heilongjiang area provides new evidence for faunal exchange between North America and Asia through Cretaceous Beringia.
