Figure 2 in A skeleton from the Middle Jurassic of Scotland illuminates an earlier origin of large pterosaurs

Figure 2. Skull of the new Middle Jurassic pterosaur Dearc sgiathanach and comparisons of pterosaur brain and ear endocasts (A–L) Photographs (A–D), segmented MCT scan renderings (E–H), and schematic drawings (I–L) of the skull (NMS G.2021.6.2) in, from top to bottom, left lateral (reversed), dorsal, right lateral, and ventral views. (M–U) Brain and inner ear endocasts of Rhamphorhynchus (based on Witmer et al.7) (M, P, and Q), Dearc (N, R, and S), and Tapejara (based on Eck et al.8) (O, T, and U), shown in the skull in left lateral view and isolated in left lateral and dorsal views, respectively. asc, anterior semi-circular canal; bp, basisphenoid; cbl, cerebellum; cer, cerebrum; ch, choana; chl, channels; cv, third cervical; d, dentary; den, dentition; e, endocast; ec, ectopterygoid; et, edentulous anterior tip; f, frontal (?); hy, hyoid; ipv, interpterygoid vacuity; itf, inferior temporal fenestra; j, jugal; la, lacrimal; md, matrix infilled dent; mx, maxilla; n, nasal; olf, olfactory bulb; opl, optic lobe; p, parietal; pm, premaxilla; po, postorbital; ppd, post-palatal depression; psc, posterior semi-circular canal; ptf, pneumatic foramen; q, quadrate; qj, quadrojugal; rapr, retroarticular process; rh, probable placement of rhamphotheca; sof, suborbital fenestra; sq, squamosal; sbtf, subtemporal fenestra; stf, superior temporal fenestra. In (E)–(L), bones that cannot be distinguished in the MCT scan due to fusion or insufficient resolution are conservatively rendered together in one color. Scale bars, 30 mm. See Figure S2.
