Comparison of the measured parameters of the mandibles in females (gray boxes) and males (white boxes) of Xya pfaendleri and X. variegata (Tridactylidae). a, d: length of the mandible (distance between the mandibular junction and the peak of the first incisor); b, e: surface of the molar ridge; c, f: number of molar slats. The box plots show the median (50th percentile) and 25th and 75th quartiles; error bars show the 10th and 90th percentiles. Filled symbols indicate outliers.

Figure 5. The food niche breadths in males (M) and females (F) of (a) Xya pfaendleri and (b) X. variegata (Orthoptera: Tridactylidae). The food niche breadth was cumulatively evaluated based on the Gini-Simpson index.

F, three schematic lateral views of the vertical ramus (from bottom to top: in Hip. amphibius, in Hex. sivalensis, in Anthracokeryx ulnifer).

Data from: A new Pliosaurus species (Sauropterygia, Plesiosauria) from the Upper Jurassic of Patagonia: new insights on the Tithonian morphological disparity of mandibular symphyseal morphology
Abstract.—Most species of the genus Pliosaurus come from the Northern Hemisphere, however a growing number of new specimens are now available from the Southern Hemisphere. Here a new species of Pliosaurus is described, the second for the genus from the Southern Hemisphere, collected from the upper Tithonian (Jurassic) levels of the Vaca Muerta Formation, Neuquén Province. Pliosaurus almanzai n. sp. is characterized by two autapomophies: angular participating in the mandibular symphysis and occipital condyle without a notochordal pit or several, irregularly-arranged grooves. Additionally P. almanzai can be differentiated from other Pliosaurus species by the following characters: trihedral teeth; nine or more symphyseal alveoli; 15-17 post symphyseal alveoli; and parasphenoid without ventral keel. Pliosaurus almanzai n. sp. shows that Pliosaurus species with nine or more 9 symphyseal alveoli persisted until the late Tithonian, contrary to previous assumptions that only species with six symphyseal alveoli were present.
Fig. 1 in Changes in Mandibular Musculature and Morphology in Response to Stemmatal Enlargement in Larvae ofThermonectus basillaris(Harris) andAcilius mediatus(Say) (Coleoptera: Dytiscidae: Dytiscinae)
Fig. 1. Anteroventral wall removed to reveal cranial interior of (A) Agabus punctatus and (B) Thermonectus basillaris. Ab 5 abductor muscle, Ad 5 adductor muscle, Ap 5 apodeme, AL 5 apodemal angle, Md 5 mandible, Sr 5 stemmatal region. Line ab determined using a basal line (ab) drawn through the center of the ball component of the ventral articulation of the right and left mandibles.
Figs. 2–4. 2 in Changes in Mandibular Musculature and Morphology in Response to Stemmatal Enlargement in Larvae ofThermonectus basillaris(Harris) andAcilius mediatus(Say) (Coleoptera: Dytiscidae: Dytiscinae)
Figs. 2–4. 2) Lateral view of Agabus punctatus showing distribution and relative size of corneal lenses of the stemmata. Each stemma is identified with an Arabic number (Schöne 1951, 1962). 3) Lateral view of Thermonectus basillaris, showing distribution and relative size of corneal lenses of the stemmata along with the cellular sacs (cs) of stemmata one and three. 4) The mandibular abductor muscle (Ab) of Thermonectus basillaris is overlain on the mandibular architecture (Md) of Agabus punctatus to illustrate the biomechanical problem resulting from stemmatal expansion. The medial displacement of the abductor apodeme places its line of action virtually inline with the mandibular joint. For a lever system to function the force vector must be at least some distance from the fulcrum.

Fig. 1 in Reexamination of the mandibular and dental morphology of the Early Jurassic mammaliaform Hadrocodium wui
Fig. 1. Lower jaws of comparative mammaliaforms. A. Hadrocodium wui Luo, Crompton, and Sun, 2001 (holotype, IVPP 8275), from the Lower Lufeng Formation, Lower Jurassic of Yunnan, China. Right mandible in lingual (A1) and labial (A2) views. B, C. Morganucodontan Dinnetherium nezorum Jenkins, Crompton, and Downs, 1983, from the Kayenta Formation, Lower Jurassic of Arizona, USA. B. An older adult (MCZ 20910). C. A young adult (MCZ 20870); modified from Crompton and Luo 1993). Younger individuals of D. nezorum have a full set of five premolars, while older individuals have lost up to two anterior premolars without replacement. The postcanine diastema developed by shedding premolars without replacement is an aging-related character of many mammaliaforms including Hadrocodium.
