Fig. 10 in Earliest Cretaceous mammals from the western United States

Fig. 10. Simplified cladogram showing known North American distribution of mammalian taxa during the Jurassic and Cretaceous. Grey bar indicates temporal range of deposits of the Lakota Formation (Lower Cretaceous: upper Berriasian–lower Barremian). Closed circles indicate mammalian fossils described in this study (temporal distributions given as mid-ranges for respective estimates). Dashed lines indicate stratigraphic range extensions of groups otherwise restricted to the Late Jurassic (Morrison Formation) or unrecorded until the Aptian–Cenomanian (Antlers, Arundel, Cloverly, and Cedar Mountain formations), highlighting the transitional composition of the Lakota assemblage. Cladogram modified from Luo (2007), geologic time scale modified from Gradstein et al. (2012).

Fig. 12 in Diversity and evolution of Hunter-Schreger Band configuration in tooth enamel of perissodactyl mammals

Fig. 12. Cladogram summarizing relationships among major lineages of Perissodactyla and the evolution of various HSB configurations. Boxes on the right indicate HSB configurations in various perissodactyl taxa. Boxes on the tree itself indicate changes in HSB configuration, as inferred from the distribution of HSB configurations given this phylogeny. The phylogeny is a conservative estimate of perissodactyl relationships drawn from Hooker (1989, 1994), Froehlich (1999), and Holbrook (1999, 2009).
