Cranial articulation out-of hyomandibula as well as thinner anterodorsal techniques abutting weakened ridge to your sphenotic facing hyomandibular factors; long, carefully game condyle revealing with hyomandibular element of sphenotic and you will pterotic; along with small, vertically-truncate posterodorsal body showing with pterotic about hyomandibular part
Articulation website into the basioccipital to own ossified Baudelot’s ligament elevated and you may rugose. Exoccipital weakly medical stitches with basioccipital, prootic, pterotic and you will epioccipital; contributing quick dorsal process to cranial articulation with Baudelot’s tendon; vagal foramen large, rounded, ventrally brought, considering a straight from anterior side of basioccipital-Baudelot’s ligament joint. Baudelot’s ligament away from supracleithrum ossified and you will big; bullet for the point medially near contact with basioccipital and you can exoccipital. Exoccipital and you will epioccipital forming evident posterolateral part from braincase you to definitely vertically buttresses extended cranial articulation out of pteroticsupracleithrum. Anterolateral deal with away from epioccipital concave and weakly sutured so you’re able to pterotic. Posterior avoid off pterotic wing brought and you will stretched ventral so you can cranial articulation off supracleithrum. Ventral edge of supraoccipital posterior techniques that have strong median straight keel.
Suspensorium ( Fig. 5k, l). Hyomandibula wide and strong, sutured so you’re able to preopercle thru lateroposterior flange, and you may metapterygoid through greater prior process; anteriorly sutured and you will posteriorly synconchondrally jointed in order to quadrate. Horizontal face that have reasonable, oblique go up between anterior techniques and preopercular flange, marking connection limitation out of internal bundles of adductor mandibulae strength. Lower crest on the medioposterior edge ventral so you can pterotic articulation, otherwise zero increased revealing process or muscle tissue supply crests dorsal so you’re able to opercle condyle. Opercle condyle oriented quite over midpoint towards the posterior dentro de out-of facial canal situated with the anterior epidermis out of adductor muscle mass crest during the quantity of opercle condyle; medial foramen off facial canal anteriorly discovered over adductor arcus palatini crest. Medial deal with having located vertical and you can crescentic adductor arcus palatini scar more prominent than in modern P. hemioliopterus ( Fig. 5m) but is contour and you will positioning comparable.
Preopercle sutured 
so you can quadrate plus hyomandibula; horizontal deal with shallowly concave building fossa to own rear areas of adductor mandibulae muscles; rear margin increased inside a smooth bend and you will likely which have nerve tunnel however, no discernable lateralis pores; no evidence of outside foramen getting symplectic canal, however, medial foramen out-of symplectic tunnel expose ranging from quadrate and preopercle.
Quadrate lateral deal with mainly shallowly concave; anteroventral blade broadly sutured so you’re able to metapterygoid; mandibular condyle greater and you will highly bilobed flanking central saddle, medial lobe of condyle braced by the straight buttress.
Weberian state-of-the-art devoid of popular middle-dorsal straight lamina; sensory arch-back complex incompletely maintained however, anteriorly projecting to contact supraoccipital and exoccipitals
Prior vertebrae ( Fig. 3b). Basic centrum articulated to help you basioccipital and significantly sutured to help you compound otherwise Weberian state-of-the-art centrum (2-4). Aortic groove unlock together midventral line, flanked by reasonable synchronous ridges collectively first and material centra; damaged before centrum of vertebra 5. Indistinct items of tripus and you will lower operating-system suspensorium remain in place; anterior limbs out of transverse procedure see compound centrum in the right-angle, wider and you will thickened laterally, generally contacting ventral articulation flange regarding supracleithrum; vertebra 5 indeterminate.
Pectoral girdle ( Figs. 5 age, f, g). Dorsal expressing procedure of cleithrum bifid, anterior limb longest, and you will overall comparable in dimensions so you can postcleithral procedure; postcleithral techniques strong and you may almost equilaterally triangular, coarsely ornamented specifically together ventral and you may ventrolateral corners lateral so you can revealing fossa away from pectoral spine. In ventral take a look at external fat off cleithrum from inside the transverse positioning which have rear maximum away from showing fossa regarding pectoral back. Mesocoracoid maybe not preserved however, increased epidermis near dorsal side of coracoid reveals the articulation site. Coracoid keel firmly increased proximally, stretching regarding halfway to help you pectoral symphysis; coracoid keel splits jointed lateral branches out of cleithrum and you can coracoid towards the equal halves; one or two parallel ridges work with to your midline horizontal limbs out of coracoid.
