Abstract Twelve new dinosaur teeth have recently been recovered from three localities in the Upper Cretaceous Nenjiang Formation of Songliao Basin. Although fragmentary, material offers enough evidence to identify following taxa: tyrannosaurids, dromaeosaurines, velociraptorines, hadrosauroids, and titanosaurs. In addition previously known dinosaurs basin, several ones identified, extending paleogeographic range related taxa. The discovery these fossil remains provides valuable insights into diversity sheds light on terrestrial ecosystem during Late
