|---|---|---|
| W. R. Nava and A. G. Martinelli 2011 | Brasiliguana prudentis differs from other squamatans in the association of the following features: triangular shaped unornamented maxilla with a high nasal process located in the anterior half of bone; weakly inclined anterior margin of the maxillary nasal process; long and thin maxillary jugal process; four conspicuously aligned foramina well above the dental margin; last five teeth placed posterior to the level of the orbital margin; teeth with labial pleurodont implantation; heterodont dentition; mid-maxillary teeth with noticeable constriction of the crown relative to the shaft as occurs in some Tropiduridae and Phrynosomatidae; midmaxillary teeth with main bulbous cusp and very small accessory mesial and distal cusps, smaller than in Tropiduridae and Phrynosomatidae, not flared; and posterior sub-conical teeth with backwardly projecting crown |
