Figures and data
Comparison of jugal morphologies among living lepidosaurs.
Note the variability in the presence and development of the posterior process, as well as the presence of an ossified jugal itself. CT scan images are from digimorph.org.
Comparison of palatine morphologies.
Blue shading indicates choanal fossa. Top image of †Cryptovaranoides referred left palatine is from Whiteside et al. [19]. Middle is the left palatine of †Helioscopos dickersonae (Squamata: Pan-Gekkota) from the Late Jurassic Morrison Formation [62]. Bottom is the right palatine of †Eoscincus ornatus (Squamata: Pan-Scincoidea) from the Late Jurassic Morrison Formation [31].
Choanal fossa character scoring.
Comparison of vomer morphologies.
Top image is †Eoscincus ornatus from Brownstein et al. (2022). Note that the rows of vomerine teeth are posteriorly placed, and the vomerine ridges are large and laterally placed. Bottom image of †Cryptovaranoides holotype is from Whiteside et al. [19].
Quadrate-squamosal articulation character scoring.
Anterior articulation of vomer and maxilla character scoring.
Presence of a medially positioned posterior mylohyoidal foramen on the mandible.
As shown, there is no identifiable foramen on the mandible of †Cryptovaranoides. Bottom image of †Cryptovaranoides holotype skull is from Whiteside et al. [19].
Comparison of the humerus of †Cryptovaranoides microlanius (from Whiteside et al. [19]) to †Puercosuchus traverorum (from [24]).
Left image of †Cryptovaranoides holotype humerus is from Whiteside et al. [19]. Ent.for, entepicondylar foramen, ect.for, ectepicondylar foramen, tr.cv, trochlear cavity, cap, capitellum, cbf, cuboid fossa, g, groove.
