FIGURE 3 in A description of the skeletal morphology of Rana pyrenaica (Anura: Ranidae), with comments on functional morphology, ecological adaptation and relationships with other Iberian ranids

FIGURE 3. Comparison of the maxilla between Iberian brown frogs. All these elements correspond to frogs with a similar SVL (around 40–50 mm). For facilitating the comparison, bones have been arranged to a similar size and laterality. Arrows: 1, inclination of the anterior margin; 2, lamina horizontalis deviating dorsally at its anterior end; 3, lamina horizontalis deviating ventrally at its posterior end.
