Fig. 1 in A review of gastrolith function with implications for fossil vertebrates and a revised classification

Fig. 1. Examples for gastroliths in extant animals. A. Bio−gastroliths of three different taxa of crustaceans. A1, Mexican dwarf orange crayfish (Cambarellus) (IPB R566); A2, blue crayfish (Procambarus) (IPB R567); A3, yabby (Cherax) (IPB R568). B. A patho−gastrolith from a prehensile−tailed porcupine (Coendou) (IPB R569), held in captivity in Wilhelma Zoo in Stuttgart/Germany. This patho−gastrolith shows the impression of the inner stomach wall. It did fill the complete stomach and presumably caused the death of the animal due to starving. C. Set of geo−gastroliths of a ptarmigan (Lagopus) (IPB R570). D. Set of geo−gastroliths of an ostrich (Struthio) (IPB R571). E. Set of geo−gastroliths of an alligator (Alligator) (IPB R572). F.

Fig. 4 in Revised classification of Acanthaceae and worldwide dichotomous keys

Fig. 4. Schematic molecular phylogeny of the Acanthaceae, which serves as the foundation for the present reclassification. Phylogeny represents current understanding of evolutionary relationships among major lineages of Acanthaceae based on numerous phylogenetic works, as cited throughout this study. Depicted are the 4 subfamilies (capital letters), 10 tribes (bold), and 19 subtribes (not in bold, not in caps) recognized in the present study. Key diagnostic morphological characters for the subfamilies and tribes are provided in Table 1 and Fig. 5. Asterisks and dashed lines indicate uncertain phylogenetic placement of Physacantheae, either within or sister to Ruellieae or Acantheae (see text).

In M. peruviana the jugal (jug) is not produced dorsal to the zygomatic process of the squamosal (zps) and the frontal process is absent or indistinct. By contrast, in M. emiliae a rounded frontal process of the jugal (fpj) extends dorsal to the zygomatic process of the squamosal, whereas in M. americana the frontal process of the jugal is well devel-oped and distinctly angular. Not to the same scale.
