Fig. 5 in A new centrosaurine from the Late Cretaceous of Alberta, Canada, and the evolution of parietal ornamentation in horned dinosaurs
Fig. 5. Schematized parietals of centrosaurine ceratopsids in dorsal view, showing possible homologies for the first four epiparietal loci. A. Albertaceratops nesmoi Ryan, 2007. B. Spinops sternbergorum gen. et sp. nov. C. Centrosaurus apertus Lambe, 1902. D. Styracosaurus albertensis Lambe, 1913. E. Rubeosaurus ovatus Gilmore, 1930. F. Einiosaurus procurvicornus Sampson, 1995. Numbers indicate locus positions. For A and B, the numbers on the right side of the parietal indicate numbering under the "traditional" scheme; numbers on the left side indicate numbering under the revised scheme proposed here. Locus numbering is the same in both the traditional and revised schemes for C, D, E, and F, and are thus presented only on the left side of the parietal for those taxa. Not to scale.

Fig. 1 in A new centrosaurine from the Late Cretaceous of Alberta, Canada, and the evolution of parietal ornamentation in horned dinosaurs
Fig. 1. Map showing the presumed location of the Spinops sternbergorum gen. et sp. nov. type locality within the area informally called the "Steveville badlands," Dinosaur Provincial Park, Alberta Canada. Charles Sternberg (unpublished data in NHMUK archives) indicated that the bone bed was one mile below the mouth of Berry Creek, and the estimated area that this covers is indicated by the grey semi−circle. Intense prospecting on the east side of the river has failed to relocate the quarry, and badlands on the west side are outside of the Park boundary and currently inaccessible for prospecting. The indicated southeast Park boundary does not include the margins of two major coulees in this region that are also within the Park. Note that the quarry for the holotype of Styracosaurus albertensis Lambe, 1913 (CMN 344) is in the southeast part of the Park. The inset photograph, courtesy of David Eberth, shows a typical view of the contact between the Dinosaur Park Formation (DPF) and Oldman Formation (OF) near the Steveville badlands.

Fig. 3 in A new eutherian mammal from the Late Cretaceous of Kazakhstan
Fig. 3. Strict consensus of the two most parsimonious trees (CI = 0.25, RI = 0.55) based on the dataset of Wible et al. (2009), as modified by Archibald and Averianov (2012), and including Zhalmouzia Averianov and Archibald gen. nov. The tree has been pruned to focus on the relationships of Zhalmouzia Averianov and Archibald gen. nov. and closely related taxa Numbers above and below nodes represent characters and character states, respectively. Only unambiguous synapomorphies are shown. Note that all of the characters are homoplastic, i.e., parallelisms or reversals.
