Benoit et al. 2021 wonder if varanopids may in fact belong to Diapsida
Answer:
Varanopids are basal to synapsids AND non-lepidosaur diapsids. We’ve known this for about a decade in the large reptile tree (LRT, 183+ taxa, subset Fig. 1).
Figure 4. Subset of the LRT focusing on basal Archosauromorpha including Vaughnictis and Cabarzia nesting at the base of the Protodiapsid-Synapsid split. Note all the large varanopids nest together here in the Synapsida, separate from small varanopids in the Protodiapsida. ” data-medium-file=”https://pterosaurheresies.files.wordpress.com/2019/01/archosauromorpha588-1.jpg?w=171″ data-large-file=”https://pterosaurheresies.files.wordpress.com/2019/01/archosauromorpha588-1.jpg?w=582″ src=”https://pterosaurheresies.files.wordpress.com/2019/01/archosauromorpha588-1.jpg” alt=”Figure 4.

and from trying to ‘Pull a Larry Martin’ by examining only the maxillary canals of several cherry-picked taxa using µCT scans without a valid phylogenetic context (Fig. 1). These authors had no idea that lepidosaur diapsids are NOT related to archosauromorph diapsids.
