Description
TABLE 2. Cranial osteological characters of Pseudogonatodes quihuai sp. nov. and its congeners P. barbouri and P. furvus based on micro-CT scans.
| Characters | P. quihuai sp. nov. (n = 3) | P. barbouri (n = 1; MCZ R-14385) | P. furvus (n = 1; MCZ R-29700) |
|---|---|---|---|
| Number of premaxillary tooth loci | 11 | 13 | 11 |
| Number of maxillary tooth loci | 22–24 | 16 | 24–25 |
| Number of dentary tooth loci | 26–30 | 23 | 26–27 |
| Number of dentary mental foramina | 5–7 | 4 | 5–6 |
| Number of maxillary foramina | 2–5 | 2 | 3–4 |
| Shape of anterior margin of maxillary facial process | rounded, merging gradually into dorsal margin | angular, with more acute transition into dorsal margin | rounded, merging gradually into dorsal margin |
| Frontal-maxilla contact | broad | broad | marginal |
| Degree of frontal fusion | partly fused or paired | completely fused | partly fused |
| Palatines in medial contact | distinctly separated | distinctly separated | yes |
| Maxilla contacts vomer and septomaxilla | no | no | yes |
| Septomaxillae | separated medially | ? | in medial contact along most of their length except anteriorly |
| Premaxilla contacts septomaxilla | yes and no | no | yes |
| Nasal contacts septomaxilla | yes | no | yes |
| Premaxilla contacts vomer | no | yes | yes |
| Vomer contacts palatine | eventually | yes | yes |
| Prefrontal contacts nasal (internally) | yes | ? | not |
| Shape of anteromedial margin between vomers | with a V-shaped notch, forming the posterior part of the rectangular shaped premaxillary-vomerine fenestra | deeply notched, resulting in the formation of an elongated premaxillary-vomerine fenestra | vomers in contact anteromedially, leaving only a small slightly triangular opening to form a premaxillary-vomerine fenestra |
| Basipterygoid process of basicranium contacts pterygoid | no | no | yes |
| Bones of braincase | completely fused, no sutures visible or completely separated | completely fused, no sutures visible | partly fused, sutures partly visible |
