In phylogenetic analysis it nested as a sister to the basal tritosaur, Lacertulus, but the Daohugou lizard lived much later. The Daohugou lizard also nested with other Early Cretaceous tritosaur lizards, Meyasaurus, Huehuecuetzpalli and Tijubina. These were difficult for professional paleontologists, like Evans and Wang (2005), to nest within the Iguania and Scleroglossa. That’s because they nest elswhere, in the Tritosauria!
Here the skull of the still unnamed Daohugou lizard is revised from an earlier reconstruction attempt. Here more details emerge with the mandible, naris, palatal and temporal regions. With these many minor modifications the phylogenetic nesting did not change.
Found and reconstructed in this round of DGS:
Epipterygoids, palate elements, a longer naris (shorter maxilla), more teeth below the orbit, lateral processes for the posterior frontal and anterior parietal, squamosal, anterior mandible elements, lacrimal.
In the lineage of pterosaurs
And because this Daohugou lizard nests within the Tritosauria, it is a sister to a similar-looking but currently unknown ancestor to pterosaurs that probably existed side-by-side with Lacertulus in the Late Permian.
