Resumo
The skull of animals provides anatomical data that assist in understanding their evolutionary
characteristics. With the aim of supporting the morphological knowledge of reptiles; we provide a detailed
description of the dermatocranium and lower jaw of Iguana iguana iguana based on the analysis
of three dried adult skeletons. The skull of this species has basal characteristics among the triangular
shape lizards, small pre-orbital region and a large snout. Bone structures are well delineated with fusion
of some bones in the caudal part and on the floor. Postfrontral, supratemporal, jugal and septomaxilla
bones then present, the quadratejugal absent, frontal and parietal are unpaired and the pineal foramen
is present in the frontal bone. In the lower jaw the splenial is reduced and the prearticular fused to articular.
The skull morphology of I. iguana iguana shows some particularities related to lifestyle habits, for
example the herbivory. The general pattern is similar to other lizards, with typical features of Iguanidae
and other unique characteristics to the species.
