摘要

最近在松辽盆地上白垩统嫩江组的三个地点发现了12颗新的恐龙牙齿。虽然碎片化，但这些材料提供了足够的证据来确定以下分类：暴龙、驰龙、迅猛龙、鸭嘴龙和泰坦龙。除了先前已知的来自盆地的恐龙外，还发现了一些新的恐龙，扩大了相关分类群的古地理范围。这些新的化石遗骸的发现为恐龙多样性提供了有价值的见解，并揭示了松辽盆地晚白垩世的陆地生态系统。

New Dinosaur Teeth from the Upper Cretaceous Nenjiang Formation in Songliao Basin, Northeast China

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