Description
FIG. 7. — Tentative skull reconstruction, in dorsal view, for Hungarobatrachus szukacsi Szentesi & Venczel, 2010. Photographs of the fused and anteriorly incomplete frontoparietals (MTM VER 2016.2546), the largest and one of the most nearly complete squamosals (MTM VER 2016.695, left squamosal), and the most nearly complete maxilla (MTM VER 2016.690, right maxilla) are overlain onto skull image of the Eocene anuran Thaumastosaurus gezei (modified from Laloy et al. 2013: fig. 3A). To improve symmetry, for the frontoparietals the intact portion from its left side was mirrored onto the right side and the left squamosal and right maxilla were mirrored onto the opposite sides of the skull. Dotted lines denote skull outline, inferred natural margins along broken surfaces for bones, and inferred contacts among bones. Although the posterior end of the maxilla is depicted as free, a shallow facet preserved on the dorsolingual surface of MTM VER 2016.690 indicates the maxilla posteriorly contacted the quadratojugal to form a closed 'cheek'. All fossil bones are depicted at their actual sizes relative to one another (i.e., they have not been arbitrarily re-sized in an attempt to improve proportions and contacts). Thaumastosaurus De Stefano, 1903 was chosen as the basis for our reconstruction, not because it is closely related (see our phylogenetic analysis and Fig. 8), but because its shape and proportions are a good fit for the available fossil bones of Hungarobatrachus. Abbreviations: fp, frontoparietals; max, maxilla; sq, squamosal.
