Fig. 9. Strict consensus of 16 equally parsimonious trees found in this cladistic analysis (length = 118 steps; consistency index (CI) = 0.475; retention index (RI) = 0.700; rescaled consistency index (RCI) = 0.332). Node A = Ankylosauria; node B = Nodosauridae; node G = Ankylosauridae. A list of the apomorphies at each lettered node is presented in appendix 3.

FIGURE 3. Facies map of the Western Interior Seaway during the deposition of the lower Turonian Scaphites whitfieldi Zone (simplified from McGookey, 1972). The localities are indicated by stars.

FIGURE 7 in Intraspecific variation through ontogeny in Late Cretaceous ammonites

FIGURE 7. Box and whiskers plot showing the intraspecific variation of each shell parameter at three ontogenetic stages. The thickness of the boxes represents the middle two quartiles and the whiskers extend to the maximum and minimum values.

FIGURE 6 in Intraspecific variation through ontogeny in Late Cretaceous ammonites

FIGURE 6. Ontogenetic trajectories of two specimens of Scaphites whitfieldi Cobban, 1951. The ratios are plotted against log diameter (dm). The specimen with the white dots (YPM 391004) shows the ontogenetic pattern typical of specimens from the siltstone and the specimen with black dots (AMNH 82703) shows the ontogenetic pattern typical of specimens from the shale.

Fig. 19 in A Complete Late Cretaceous Iguanian (Squamata, Reptilia) from the Gobi and Identification of a New Iguanian Clade

Fig. 19. Temporally calibrated cladogram showing the phylogenetic hypothesis generated by the current study. Note that many terminal taxa in this cladogram (Scincogekkonomorpha, Acrodonta, 'priscagamines', Hoplocercidae, Polychrotidae, and Tropiduridae) were subdivided for the actual cladistic analysis performed in this study (see appendix 1). Taxonomic intervals are approximate and derived primarily from Estes (1983), but supplemented by Norell and de Queiroz (1991), Evans (1994), and Conrad et al. (in press). Timescale adapted from Gradstein et al. (1999). Bremer supports for all displayed iguanian nodes is 1, except the polychrotid-corytophanid clade.

The suprascapula is show as
