FIGURE 13 in Comparison of Miocene to early Pleistocene-aged Castor californicus (Rodentia: Castoridae) to extant beavers and implications for the evolution of Castor in North America
FIGURE 13. Boxplots for (A) articular width of humeral distal end (HDAW), (B) femoral epicondylar breadth (FeEB), (C) anteroposterior diameter of tibia distal epiphysis (TDEAPD), (D) anteroposterior diameter of third metatarsal (MT3APD), and (E) mediolateral diameter of fourth metatarsal (MT4MLD) of Castor canadensis and C. californicus, which exhibit differences in mean values and no overlap in range values. See Table 17 for descriptive statistics, coefficients of variation, and ANOVA results.

FIGURE 14 in Fossil snakes of the Penny Creek Local Fauna from Webster County, Nebraska, USA, and the first record of snakes from the Early Clarendonian (12.5-12 Ma) of North America
FIGURE 14. Complete-linkage hierarchical cluster analysis showing the relative similarity of snake assemblages from 19 Barstovian-Blancan localities in Nebraska based on presence-absence..
