(a) Phylogenetic position of Retinosaurus hkamtiensis (GRS 29689) using a combined data set of morphological and molecular data, including all characters (i.e. not coding ontogenetically variable characters of Retinosaurus as ?), and treating characters as additive following Gauthier et al.2. Terminals and groups numbered a–c were identified as wildcard taxa, therefore the strict consensus was calculated without them, and their alternative positions indicated in the tree. Using the combined data set, R. hkamtiensis was recovered as a stem-xantusiid. Numbers below nodes indicate Bremer support values. Letter at nodes indicate alternative positions of wildcard taxa (right). Nodes with no support values were collapsed when wildcards were included in the consensus. (b) Inset left side of R. hkamtiensis showing the preservation of the eyelids and circumorbital bones.
