Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. M. Hamilton et al. 2023 | Anguimorph lizards typically with thick, polygonal, nonimbricating, non-compound osteoderms bearing ridge-and-pit ornamentation but not keels or tubercles, fused to the frontal and other bones of the skull roof. Frontals remain paired in adults. Cristae cranii are well-developed but typically do not meet ventrally to enclose the olfactory canal. |
