Basioccipital weakly sutured so you’re able to exoccipital and you will prootic; vertebral-particularly mutual with very first centrum

Cranial articulation of hyomandibula also slender anterodorsal procedure abutting weakened ridge towards sphenotic in front of hyomandibular part; long, gently circular condyle showing which have hyomandibular facet of sphenotic and you can pterotic; including brief, vertically-truncate posterodorsal facial skin expressing which have pterotic behind hyomandibular part

Articulation web site to your basioccipital to possess ossified Baudelot’s ligament increased and you may rugose. Exoccipital weakly sutures that have basioccipital, prootic, pterotic and epioccipital; adding short dorsal way to cranial articulation having Baudelot’s ligament; vagal foramen highest, circular, ventrally directed, predicated on a vertical from anterior side of basioccipital-Baudelot’s tendon joint. Sex dating Baudelot’s tendon out-of supracleithrum ossified and you may big; round in point medially close contact with basioccipital and you may exoccipital. Exoccipital and you may epioccipital forming clear posterolateral place off braincase one vertically buttresses prolonged cranial articulation off pteroticsupracleithrum. Anterolateral face off epioccipital concave and weakly sutured so you can pterotic. Posterior avoid regarding pterotic wing introduced and you will stretched ventral to cranial articulation of supracleithrum. Ventral side of supraoccipital rear procedure which have strong average vertical keel.

Suspensorium ( Fig. 5k, l). Hyomandibula wide and you can strong, sutured in order to preopercle via lateroposterior flange, and you can metapterygoid thru large anterior process; anteriorly sutured and you will posteriorly synconchondrally jointed in order to quadrate. Horizontal deal with which have reasonable, oblique go up between prior processes and you will preopercular flange, establishing connection restrict of interior bundles out-of adductor mandibulae muscle mass. Reduced crest for the medioposterior boundary ventral so you’re able to pterotic articulation, if not zero enlarged revealing process otherwise muscle source crests dorsal so you’re able to opercle condyle. Opercle condyle situated a little more than midpoint to the rear dentro de from face tunnel situated to your prior epidermis from adductor muscles crest during the level of opercle condyle; medial foramen of facial canal anteriorly receive above adductor arcus palatini crest. Medial deal with with situated vertical and crescentic adductor arcus palatini scar even more prominent compared to progressive P. hemioliopterus ( Fig. 5m) it is figure and you can location similar.

Preopercle sutured to help you quadrate also hyomandibula; lateral deal with shallowly concave developing fossa to possess posterior parts of adductor mandibulae strength; posterior margin raised during the a soft contour and you can most likely which have neurological canal however, zero discernable lateralis pores; no proof additional foramen to possess symplectic tunnel, however, medial foramen regarding symplectic tunnel introduce ranging from quadrate and you will preopercle.

Quadrate lateral deal with mostly shallowly concave; anteroventral knife broadly sutured so you can metapterygoid; mandibular condyle broad and you may strongly bilobed flanking main saddle, medial lobe off condyle braced of the vertical buttress.

Weberian advanced without having common middle-dorsal vertical lamina; neural arc-spine state-of-the-art incompletely managed however, anteriorly projecting to get hold of supraoccipital and you can exoccipitals

Anterior vertebrae ( Fig. 3b). Earliest centrum articulated so you’re able to basioccipital and you can profoundly sutured so you can substance or Weberian complex centrum (2-4). Aortic groove open collectively midventral line, flanked by reduced parallel ridges together very first and you will compound centra; broken before centrum from vertebra 5. Indistinct bits of tripus and you will low os suspensorium remain in lay; anterior branches off transverse process see substance centrum from the right angle, wide and thickened sideways, generally contacting ventral articulation flange out-of supracleithrum; vertebra 5 indeterminate.

Pectoral girdle ( Figs. 5 e, f, g). Dorsal showing procedure for cleithrum bifid, prior limb longest, and you may total similar in size so you can postcleithral processes; postcleithral processes deep and almost equilaterally triangular, coarsely ornamented specifically collectively ventral and you can ventrolateral sides horizontal so you’re able to revealing fossa away from pectoral spine. Within the ventral have a look at outward pouch out of cleithrum in the transverse alignment that have posterior maximum away from expressing fossa off pectoral lower back. Mesocoracoid not maintained however, raised surface near dorsal side of coracoid suggests the articulation web site. Coracoid keel strongly elevated proximally, extending throughout the halfway so you can pectoral symphysis; coracoid keel divides jointed lateral limbs from cleithrum and you can coracoid to your equal halves; one or two parallel ridges work on toward midline horizontal limbs out of coracoid.
