描述了白垩纪晚期鸭嘴龙恐龙的一个新种——Lambeosaurus laticaudus。 ？ Lambeosaurus laticaudus 的前上颌骨有一个开放的鼻管，类似于兰贝龙的鼻管，但尾椎上的神经和血液棘大大延长，类似于高棘亚龙。后一个特征说明了两个属之间的形态平行性。沉积学、埋藏学和形态学数据表明？ L. laticaudus 主要是水生动物，在坎帕尼亚时期生活在下加利福尼亚州太平洋边缘的近岸河口。
A new species of Late Cretaceous hadrosaurian dinosaur, ?Lambeosaurus laticaudus, is described. ? Lambeosaurus laticaudus has an open narial canal on the premaxilla like that of Lam- beosaurus lambei, but greatly elongate neural and haemal spines on the caudal vertebrae similar to those of Hypacrosaurus altispinus. This latter characteristic illustrates morphological parallelism between the two genera. Sedimentologic, taphonomic and morphologic data indicate that ? L. laticaudus was dominantly aquatic and lived in near shore estuaries along the Pacific margin of Baja California during the Campanian.
