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 Lambeosaurus 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.
