Fig. 5 in Morphology, Phylogenetic Taxonomy, And Systematics Of Ichthyornis And Apatornis (Avialae: Ornithurae)
Fig. 5. Distal humeral dimensions (in millimeters) of four uncrushed YPM Ichthyornis dispar specimens (YPM 1450, YPM 1464, YPM 1738, YPM 9685).
Fig. 6 in Morphology, Phylogenetic Taxonomy, And Systematics Of Ichthyornis And Apatornis (Avialae: Ornithurae)
Fig. 6. Size and stratigraphic position of individuals referred to Ichthyornis dispar interpreted as anagenetic change. Data points represent total humerus length of the indicated specimen(s) in millimeters. The relative size of specimens without data points, those lacking complete humeri, was estimated (i.e., YPM 1738, 1765, SMM 2139, USNM 22820, TMM 42522–1, and Cenomanian specimens, SMNH P2077.67, SMNH P2077.111, SMNH P2077.112, SMNH P2487.5). Shaded regions indicate size variation for each time period interpreted as anagenetic change in a single lineage.
FIG. 12 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 12. Maximum-likelihood reconstruction of geographic range evolution for the erethizontid crown clade. See table 1 (footnote) for range descriptors and table 8 for divergence-date estimates.
FIG. 10 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 10. Coendou prehensilis with erected cranial quills. The inflated nasofrontal sinuses of this species provide increased surface area for quill deployment, and their convex margins allow erected quills to point anteriorly and laterally to protect adjacent soft tissues. Photographed at the Frankfurt Zoo in 2008 (courtesy of Marek Polster).
FIG. 9 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 9. Maximum-likelihood reconstructions of ancestral phenotypes for three morphological characters of Recent erethizontids. Branch tips representing species of Coendou are labeled with corresponding epithets only. See text for character definitions and scoring criteria and table 8 for divergence-date estimates. Pie diagrams at internal nodes represent estimated probabilities of alternative states.
FIG. 8 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 8. Lateral cranial views: A, Coendou prehensilis (AMNH 134064); B, C. melanurus (AMNH 266565). The inflated nasofrontal sinuses of C. prehensilis (type species of the genus Coendou) result in a strongly convex dorsal profile by contrast with the flat dorsal profile of C. melanurus (referred to Sphiggurus by some authors; see text). Both skulls are life size (×1).
FIG. 7 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 7. Coendou rufescens (FMNH 88524), previously referred to Echinoprocta by many authors. This is a shorttailed species that (like C. prehensilis) appears completely spiny because the quills conceal its short, sparse fur.
FIG. 6 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 6. Coendou melanurus (AMNH 266565), referred to Sphiggurus by Husson (1978) and other authors. This is a long-tailed species in which the quills are concealed beneath long, dense fur.
FIG. 5 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 5. Coendou prehensilis (INPA 2875), the type species of Coendou. This is a long-tailed species that appears completely spiny because the quills conceal its short, sparse fur.
FIG. 4. Maximum-likelihood phylogeny for 45 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 4. Maximum-likelihood phylogeny for 45 ingroup (erethizontid) terminals; outgroup taxa are not shown. Labeling conventions and nodal support statistics are the same as in figure 3. Capital letters (A, B, C) indicate unnamed clades discussed in the text.
FIG. 3 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 3. Strict consensus of 14 equally most-parsimonious trees for 29 unique erethizontid cytochrome-b haplotypes (only ingroup relationships are shown). Sequenced specimens of Coendou are identified by country of origin, next-largest political unit (state, department, or province), collection locality number (mapped in fig. 1), and an alphanumeric identifier (tissue, voucher, or GenBank accession number; see tables 2 and 3). Nodal support values are bootstrap percentages.
FIG. 1 in Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography
FIG. 1. Collection localities of sequenced specimens of Neotropical erethizontids (Chaetomys and Coendou). See gazetteer (appendix 1) for geographic coordinates and other information.

Figure 10. A in The phylogeny and taxonomy of Hippopotamidae (Mammalia: Artiodactyla): a review based on morphology and cladistic analysis
Figure 10. A new phylogeny for the Hippopotamidae. Geographical distribution: anot Eastern African, but from Abu Dhabi, the Arab United Emirates, the Arabic Peninsula (see Gentry, 1999); bknown in Eastern Africa but also in Oubeidiyeh, Israel (see Faure, 1986) and maybe in Algeria (Geraads, 1980); cknown in Africa but also in continental Europe (see Mazza, 1995).
Figure 9 in The phylogeny and taxonomy of Hippopotamidae (Mammalia: Artiodactyla): a review based on morphology and cladistic analysis
Figure 9. Mandibular anatomy within the Hippopotamidae. This figure shows the new taxonomic divisions of the family Hippopotamidae and, for each discussed taxon, some of the mandibular characters that provided additional support to the clades identified in the parsimony analysis (boxes in this figure). These features include: the general shape of the mandible, with expansion of the canine processes and relative length of the symphysis (seen in the dorsal outlines); the shape of the symphysis sagittal cross section; the length of the premolar row relative to the length of the molar row. The figure shows the following features for the taxa listed under each genus name: Saotherium, very inclined symphysis with thin cross-section and poorly developed canine processes; Archaeopotamus, relatively long and shallow symphysis with poorly developed canine processes and longer premolar rows than in any other clade; Hexaprotodon, wide symphysis but with poorly differentiated canine processes, very robust symphysis in cross section; Choeropsis, very short symphysis globular in cross section and poorly developed canine processes; Hippopotamus and aff. Hippopotamus, short symphysis globular in crosssection (lacking a projected incisor alveolar process) and strong extension of the canine processes – the latter feature being not salient in the Afar species (aff. Hip. coryndoni, aff. Hip. afarensis) and aff. Hip. cf. protamphibius from Kanapoi.
