Skull of Mesosaurus tenuidens in right lateral view showing temporal opening

Summary[edit]

Description
English: Original figure caption: Skull of Mesosaurus tenuidens (GP-2E-669a) in right lateral view showing the lower temporal fenestra; picture (A) and interpretive labeled line drawing (B). This specimen is an almost complete skull and part of the postcranial skeleton (not shown) housed in the Fossil Vertebrate Collection of Instituto de Geociencias, São Paulo University. Scale bar: 10 mm. a, angular; ax, axis; cev, cervical vertebra; d, dentary; f, frontal; j, jugal; l, lacrimal; ltf, lower temporal fenestra; mx, maxila; n, nasal; p, parietal; pf, postfrontal; po, postorbital; pp, postparietal; prf, prefrontal; q, quadrate; qj, quadratojugal; sa, surangular; sm, septomaxilla; sp, splenial; sq, squamosal; st, supratemporal.

Deutsch: Schädel von Mesosaurus tenuidens (Exemplar.-Nr. GP-2E-669a) aus dem Unterperm des Paraná-Beckens (Südamerika) in rechtsseitiger Ansicht mit Öffnung im Schläfenbereich (A), und interpretative, beschriftete Linienzeichnung (B). Dieses Exemplar besteht aus einem fast vollständigen Schädel und einem unvollständigen postkranialen Skelett (nicht im Bild zu sehen) und wird in der Sammlung fossiler Wirbeltiere des Instituto de Geociencias (GP) der Universität von São Paulo aufbewahrt. Länge des Maßstabsbalkens: 10 mm. a, Angulare; ax, Axis; cev, Halswirbel; d, Dentale; f, Frontale; j, Jugale; l, Lacrimale; ltf, unteres Schläfenfenster; mx, Maxillare; n, Nasale; p, Parietale; pf, Postfrontale; po, Postorbitale; pp, Postparietale; prf, Präfrontale; q, Quadratum; qj, Quadratojugale; sa, Surangulare; sm, Septomaxillare; sp, Spleniale; sq, Squamosum; st, Supratemporale.
Wie man anhand der Beschriftung sieht, wird die Öffnung im Schläfenbereich von den Autoren des Bildes und des entsprechenden Aufsatzes (siehe untenstehende Angaben dazu), als reguläres Schläfenfenster betrachtet – eine nicht unumstrittene Sichtweise. Andere Bearbeiter vermuten ein taphonomisches Phänomen dahinter.
