Image: Chasmosaurine specimens from the Dinosaur Park Formation

Description: Stratigraphic positions of chasmosaurine specimens from the Dinosaur Park Formation. Specimens above the regional disconformity (0 m) separating the Dinosaur Park and Oldman formations (error bars ±5 m). Specimens are shown on right in ascending stratigraphic order, in dorsal and lateral views. CMN 41357 was collected either at the base of or within the Lethbridge Coal Zone (LCZ), and TMP 1998.102.0008 was collected somewhere within the LCZ, as indicated by the vertical dashed lines. DPFZ = Dinosaur Park Faunal Zone ([15, 16]). Plaster reconstruction = grey. [planned for page width].
