Remains of Late Cretaceous toothed pterosaurs such as ornithocheirids and lonchodectids are almost unknown for post Cenomanian strata. Here we describe teeth referrable to ornithocheirid pterosaurs from the Upper Cretaceous (Santonian) Dmitrov Formation of Ryazan region, European Russia. The teeth are somewhat worn, but retain sufficient features to satisfactorily refer them to Ornithocheiroidea, including their slender curved shape, presence of faint reticulated ribbing and a curved margin of the enamel - dentine contact. Although occurring in a Santonian deposit, the teeth are most likely derived from the underlying Cenomanian Yakhroma Formation. Although ornithocheirid teeth have been reported previously from European Russia, these teeth are the first from this region and the first evidence for Pterosauria in the Dmitrov Formation, which is better known for its elasmobranch and marine reptile assemblage.

晚白垩世有齿翼龙的遗骸，例如鸟手龙科和长龙科龙科，在森诺曼阶后的地层中几乎是未知的。在这里，我们描述了与来自俄罗斯欧洲梁赞地区上白垩纪（桑顿阶）德米特洛夫组的鸟手龙类翼龙相关的牙齿。牙齿有些磨损，但保留了足够的特征，可以令人满意地将它们归类为鸟手足目，包括它们细长的弯曲形状、微弱的网状棱纹和牙釉质与牙本质接触的弯曲边缘。尽管发生在 Santonian 矿床中，但这些牙齿很可能来自下伏的 Cenomanian Yakhroma 地层。虽然之前曾在俄罗斯欧洲报道过鸟爪科动物的牙齿，但这些牙齿是该地区的第一颗牙齿，也是 Dmitrov 组中翼龙类的第一个证据，
