摘要描述了一种新的长喙齿象Rhynchodercetis regio，sp. nov.，来自墨西哥东北部努埃沃州瓦列西约的上白垩纪（土仑期）沉积物，Rhynchodercetis regio与Rhynchodercetis的其他物种的不同之处在于独特的特征组合，包括头部与标准长度的比例，眶前区的长度，以及存在interocle和短下颌骨。这种鱼在墨西哥的出现扩大了Rhynchodercetis在晚白垩世期间在北美的已知分布，从内海的加拿大部分到墨西哥，在特提斯西部地区。
Abstract Description of Rhynchodercetis regio, sp. nov., from Upper Cretaceous (Turonian) sediments of Vallecillo, State of Nuevo León, northeastern Mexico is based on three specimens. Rhynchodercetis regio differs from the other species of Rhynchodercetis in the exclusive combination of characters that includes the proportions of the head with its standard length, the length of the preorbital area, and the presence of an interopercle and a short mandibule. The occurrence of this fish in Mexico expands the known distribution of Rhynchodercetis in North America during the Late Cretaceous, from the Canadian portion of the Interior Sea to Mexico, in the western Tethys area.
