Classification

Restoration of the head

Laiyangosaurus is a member of the saurolophine tribe Edmontosaurini. A number of specimens referred to Laiyangosaurus (IVPP V23405.1, V23403.1, V23402.1, V23404, V23402.7) apparently belong to kritosaurin and lambeosaurine hadrosaurids.^[1]

The Wangshi Series of Shandong Province has yielded a considerable amount of fossil material, including the remains of insects, plants and other vertebrates, including dinosaurs and dinosaur eggs.^[2]
