| M. Bosselaers and D. K. Munsterman 2022 | Persufflatius renefraaijeni n. gen., n. sp. is closely related to Peloce- tus calvertensis, Uranocetus gramensis and Parietobalaena palmeri in having a rod-like posterior process of the petrotympanic. It differs from eomysticetids, balaenids, Atlanticetus patulus, Diorocetus hiatus and the cetotheriids Brandtocetus chongulek Gol’din & Startsev, 2014, Cetotherium rathkii Brandt, 1843, Heterocetus affinis and Piscobalaena Pilleri & Siber, 1989 in having a squamosal cleft (Bisconti: ch. 114; Duboys de Lavi- gerie: ch. 107), and from all known mysticetes except Pari- etobalaena, in this cleft being ‘smiley’-shaped (semi-circular, dorsally concave). It further differs from eomysticetids in having a more anteriorly projected supraoccipital and parietal; from balaenids in having a concave anterior supraoccipital dorsally (Bisconti: ch. 135; Duboys de Lavigerie: ch. 113), a small but prominent attachment surface (‘paired tubercles’) for the neck muscles on the anterior supraoccipital (Bisconti: ch. 85; Duboys de Lavigerie: ch. 109), a posterodorsally inclined superior part of the posterior wall of the squamosal fossa, and a wide temporal fossa (Bisconti: ch. 110); from ‘Balaenoptera’ ryani Hanna & McLellan, 1924 in having a wide semi-circular posterior temporal crest (Bisconti: ch. 107), a posterodorsally inclined superior part of the posterior wall of the squamosal fossa (Bisconti: ch. 113), a parietal that anteriorly overhangs the temporal fossa (Bisconti: ch. 78), and a relatively large peri- otic having a prominent, deep groove for the tensor tympani muscle (Bisconti: ch. 196; Duboys de Lavigerie, chs 160, 161), the cochlear aqueduct being not confluent with the fenestra cochlearis (Bisconti, chs 215, 216; Duboys de Lavigerie: ch. 174), and a small, not-inflated pars cochlearis (Bisconti: ch. 213); from balaenopterids and eschrichtiids in having the parietal broadly exposed at the vertex (Bisconti, chs 82, 83) and a Pelocetus-like periotic with a pars cochlearis that is not cranially elongated (Bisconti: ch. 211; Duboys de Lavigerie: ch. 144); from Parietobalaena palmeri and P. laxata by the large, strongly inflated and ventrally expanded postglenoid process; from Atlanticetus patulus, Diorocetus hiatus, Pelocetus calvertensis, Tiucetus rosae, ‘Diorocetus’ shobarensis, ‘Diorocetus’ chichibuensis, Isanacetus laticephalus and Parietobalaena in having a bell-shaped supraoccipital (Bisconti, chs 140, 141, 142; Duboys de Lavigerie: ch. 112), large inflated postglenoid processes and wide rounded exoccipitals, confluent with the squamosal (Duboys de Lavigerie: ch. 74); from Uranocetus gramensis in having a large inflated postglenoid process, anter- oposteriorly much longer squamosals (squamosal + exoccipital length: 170 mm) and wide rounded exoccipitals; from Isan- acetus, Parietobalaena and ‘Diorocetus’ chichibuensis in them having a narrow body of the periotic with no sign of lateral inflation; from Diorocetus hiatus in lacking a ridge posteriorly bordering the facial sulcus on the compound posterior process (Duboys de Lavigerie: ch. 185); from all cetotheriids except Cephalotropis nectus and Joumocetus shimizui in having parietals that are well exposed on the skull vertex (Bisconti, chs 82, 83); from Diorocetus, Uranocetus, Tiucetus and Parietobalaena in lacking an external occipital crest on the anterior supraoc- cipital (Bisconti: ch. 81; Duboys de Lavigerie: ch. 114); from all BnBB in having a bell-shaped supraoccipital (except maybe for Uranocetus (Steeman 2009); due to breakage the exact shape of the latter’s supraoccipital is not very clear) (Bisconti, chs 140, 141, 142; Duboys de Lavigerie: ch. 112); differs from Atlanticetus patulus by the deeply excavated tensor tympani fossa (Bisconti: ch. 196; Duboys de Lavigerie: ch. 160), the different rod-like posterior process (Duboys de Lavigerie: ch. 188), slit-like aqueducts (Bisconti: ch. 217; Duboys de Lavi- gerie: ch. 172) and the strongly inflated postglenoid process of the squamosal and from ‘Plesiocetus’ dubius (IRSNB M 652), ‘Plesiocetus’ burtinii (IRSNB M 676), Mesocetus latifrons (IRSNB M 567) and Idiocetus longifrons (IRSNB M 719) in having a small cochlea, a slit-like cochlear aqueduct foramen (except ‘P’. dubius) (Bisconti: ch. 217; Duboys de Lavigerie:ch. 172), a very different rod-like compound posterior process (Duboys de Lavigerie: ch. 188) and a strongly inflated postgle- noid process of the squamosal. Differs from Atlanticetus patulus, Heterocetus affinis and Cephalotropis nectus in that all three taxa have a (sub-)diamond-shaped compound posterior process of the petrotympanic in ventral view; in addition, the shape of the anterior process of the periotic and the cranial openings of the promontorium also differ (Duboys de Lavigerie, chs 168, 169). The species is smaller than Pelocetus calvertensis, Uranocetus gramensis and Atlanticetus patulus, and larger than Tiucetus rosae (Fig. 7). |
