Fig. 1 in Comparative cranial osteology of subadult eucentrosauran ceratopsid dinosaurs from the Two Medicine Formation, Montana, indicates sequence of ornamentation development and complex supraorbital ontogenetic change
Fig. 1. Lateral views of articulated crania of subadult eucentrosaurans from the Campanian Two Medicine Formation, Montana, USA. A. Einiosaurus procurvicornis Sampson, 1995, MOR 456 8-8-87-1. B.

Face of MOR 591 mirrored, with parietosquamosal frill superimposed. The contact outlines between the postorbital, jugal, and squamosal in A2 are estimated due to lack of externally visible sutures and may appear different from MOR 591 due to some breaks and gaps. P4–P7, parietal processes.

Figure 3 in Cenozoic dinosaurs in South America - revisited
Figure 3. Size comparison of the two known snouts of Barinasuchus arveloi with skulls of another large sebecosuchian (Bretesuchus bonapartei), Crocodylus, and selected carnivorous mammals. The white portion of the image of Bretesuchus is intended to indicate the amount of the skull known, not the actual form of the missing portion of the skull. The skull of Crocodylus is scaled to the size of the largest known skull of Crocodylus porosus according to Greer (1974). (Barinasuchus from Paolillo and Linares, 2007, and Buffetaut and Hoffstetter, 1977; Bretesuchus modified from Gasparini et al., 1993; Crocodylus modified from Schumacher, 1973; Andrewsarchus from Osborn, 1924; U. arctos from Allen, 1902; P. spelaea from Gromova et al., 1964; Smilodon from Scheele, 1955.)
Figure 4 in Cenozoic dinosaurs in South America - revisited
Figure 4. Size comparison of Barinasuchus (here represented by the silhouette of Stratiotosuchus) with contemporaneous large South American mammals.These particular mammalian taxa are Patagonian, and may not have lived in the same region as the northern South AmericanBarinasuchus.
Figure 2 in Cenozoic dinosaurs in South America - revisited
Figure 2. Size comparison of Barinasuchus and Daspletosaurus (CMN 8506). The silhouette representing Barinasuchus is that of Stratiotosuchus appropriately enlarged, the actual size of Stratiotosuchus is indicated at lower right. (Daspletosaurus skeleton from Russell,1970;Stratiotosuchus skeleton modified from Riff et al., 2012.)
Figure 1 in Cenozoic dinosaurs in South America - revisited
Figure 1. Size comparison of the snout of Barinasuchus with the skull of Daspletosaurus: a, skull of Daspletosaurus torosus (CMN 8506); b, snout and left dentary of the largest known specimen of Barinasuchus arveloi (MAAT-0260) with measurements; c, snout of B. arveloi superimposed over the outline of the skull of Baurusuchus pachecoi (DGM 299-R), to estimate the length of the Barinasuchus skull. (a, modified from Russell, 1970; b, from Paolillo and Linares, 2007; B. pachecoi from Carvalho et al., 2005.)

FIGURE 3 in Forelimb motion and orientation in the ornithischian dinosaurs Styracosaurus and Thescelosaurus, and its implications for locomotion and other behavior
FIGURE 3. Stratigraphic distribution of ornithopod and basal ornithischian ichnogenera (after Lockley et al., 2003, 2009; Stanford et al., 2004; Díaz-Martínez et al., 2015; Salisbury et al., 2016), with time-calibrated phylogeny of Ornithopoda (after McDonald, 2012; Dieudonné et al., 2020; Kobayashi et al., 2021). Blue parts of the cladogram and blue manus and pes prints indicate taxa and ichnotaxa with manus enclosed in a mitten-like sheath of soft tissue. Striped blue and black on the cladogram indicates uncertainty: known fossils don't include enough of the manus to determine whether the fingers were enclosed in a mitten-like sheath of soft tissue. The unnamed tracks from Spain are those described by Pérez-Lorente et al. (1997).
