摘要：
Three pachycephalosaurid frontoparietals from the Foremost Formation (Campanian) of South Alberta, Canada, are described and assigned to the genus Stegoceras Lambe 1902 on the basis of measurements. Measurements and indices suggest that all of the specimens originate from male animals. The specimens are the oldest fossil record of this genus. The possibility is discussed, that they represent a species that could be an ancestor of the North American Stegoceras validum and/or the Mongolian Prenocephale prenes. © 1997 E.
