FIGURE 8 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 8. Comparison of the urostyle 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, straighter ventral margin of the urostyle; 2, shorter neural crest.
