FIG. 23 in The discovery of a Balaenomorpha (Persufflatius renefraaijeni n. gen., n. sp.) from the upper Miocene of the Netherlands sheds new light on the cranial anatomy of archaic rorqual relatives

FIG. 23. — Anteroventral (left) and posterodorsal (right) views of Persufflatius renefraaijeni n. gen., n. sp., with a schematic indication of expanded ('inflated') regions (compared to the neurocranium of Pelocetus, Uranocetus and Piscobalaena). Note the sub-triangular ventral squamosal fossa (1), with a strong ventrally protruding wall (D) and the wide, rounded dorsal squamosal fossa (2). A, dense mediodorsal parietal; B, dense anterodorsal supraoccipital; C, layered anteromedioventral squamosal body; D, inflated ventral squamosal wall; E, inflated and laterally expanded anterior surface of the postglenoid process; F, inflated and laterally expanded posterolateral postglenoid process; G, inflated laterodorsal squamosal and posterolaterodorsal zygomatic process; H, inflated and mediolaterally expanded exoccipital. Scale bars: 10 cm.
