摘要最近在墨西哥东北部的上白垩纪进行的工作已经产生了脊椎动物遗骸的多样性。对于可归入有鳞目的标本，无论是新的还是旧的，这里都提供了一个注释目录，其中总结了每个标本的地质背景和形态特征。所有的标本似乎都是海洋有鳞类动物，包括一个类似翼龙的爬行动物，保留了外皮结构，几个可能代表沧龙类的椎骨，第一个从重要的颅骨材料中发现的墨西哥沧龙，一个孤立的沧龙下颌骨碎片，以及Amphekepubis johnsoni的正模标本（被认为属于沧龙）。这些发现是吉祥的，应该会加深我们对古生物地理和进化模式的理解
Abstract Recent work in the Upper Cretaceous of northeastern Mexico has produced a diversity of vertebrate remains. For specimens referable to Squamata, both old and new, an annotated catalogue is here provided, wherein are summarised the geological context and morphological features of each specimen. All specimens appear to represent marine squamates, including an aigialosaur-like reptile preserving integumentary structures, several vertebrae possibly representing mosasauroids, the first Mexican mosasaur known from significant cranial material, an isolated mosasaur mandibular fragment, and the holotype of Amphekepubis johnsoni (considered to belong to Mosasaurus). These discoveries are auspicious and should deepen our understanding of palaeobiogeographic and evolutionary patterns
