Basioccipital weakly sutured so you can exoccipital and you may prootic; vertebral-for example shared having earliest centrum

Cranial articulation of hyomandibula together with thinner anterodorsal procedure abutting poor ridge on the sphenotic before hyomandibular facet; enough time, softly circular condyle showing which have hyomandibular part of sphenotic and you will pterotic; including small, vertically-truncate posterodorsal facial skin showing having pterotic trailing hyomandibular part

Articulation website into the basioccipital getting ossified Baudelot’s tendon increased and you will rugose. Exoccipital weakly sutures that have basioccipital, prootic, pterotic and you may epioccipital; contributing quick dorsal strategy to cranial articulation that have Baudelot’s ligament; vagal foramen highest, rounded, ventrally directed, predicated on a straight from anterior side of basioccipital-Baudelot’s tendon combined. Baudelot’s ligament off supracleithrum ossified and you can big; round inside area medially near connection with basioccipital and you may exoccipital. Exoccipital and epioccipital forming sharp posterolateral part of braincase you to vertically buttresses longer cranial articulation from pteroticsupracleithrum. Anterolateral deal with away from epioccipital concave and you will weakly sutured so you’re able to pterotic. Rear prevent regarding pterotic wing put and you can extended ventral to help you cranial articulation off supracleithrum. Ventral side of supraoccipital rear procedure having solid median vertical keel.

Suspensorium ( Fig. 5k, l). Hyomandibula broad and you will strong, sutured in order to preopercle via lateroposterior flange, and you will metapterygoid through large anterior procedure; anteriorly sutured and you may posteriorly synconchondrally jointed in order to quadrate. Lateral deal with with lowest, oblique rise between anterior process and you may preopercular flange, establishing connection restrict regarding interior packages out-of adductor mandibulae muscle tissue. Low crest toward medioposterior edge ventral in order to pterotic articulation, or even zero expanded showing techniques otherwise muscle origin crests dorsal so you’re able to opercle condyle. Opercle condyle founded somewhat a lot more than midpoint towards posterior dentro de away from face canal located to the anterior epidermis regarding adductor strength crest at the quantity of opercle condyle; medial foramen of facial canal anteriorly discover significantly more bez vД›kovГЅ rozdГ­l datovГЎnГ­ datovГЎnГ­ lokalit than adductor arcus palatini crest. Medial deal with that have situated straight and you can crescentic adductor arcus palatini scar alot more prominent compared to modern P. hemioliopterus ( Fig. 5m) it is figure and you will position equivalent.

Preopercle sutured to quadrate together with hyomandibula; lateral deal with shallowly concave developing fossa for posterior parts of adductor mandibulae muscles; rear margin increased for the a gentle bend and you can almost certainly having neurological tunnel but no discernable lateralis skin pores; zero evidence of outside foramen for symplectic tunnel, but medial foramen out of symplectic tunnel introduce between quadrate and you can preopercle.

Quadrate lateral deal with generally shallowly concave; anteroventral blade generally sutured in order to metapterygoid; mandibular condyle greater and you can highly bilobed flanking central seat, medial lobe from condyle braced from the vertical buttress.

Weberian advanced without having popular middle-dorsal vertical lamina; neural arc-back complex incompletely kept but anteriorly projecting to contact supraoccipital and you will exoccipitals

Anterior backbone ( Fig. 3b). First centrum articulated to basioccipital and you may profoundly sutured to help you material or Weberian advanced centrum (2-4). Aortic groove open along midventral range, flanked from the reduced synchronous ridges collectively earliest and you will compound centra; broken in advance of centrum out of vertebra 5. Indistinct items of tripus and you may low operating system suspensorium stay in place; prior limbs off transverse processes satisfy material centrum during the right-angle, large and you will thickened laterally, generally calling ventral articulation flange from supracleithrum; vertebra 5 indeterminate.

Pectoral girdle ( Figs. 5 elizabeth, f, g). Dorsal revealing means of cleithrum bifid, anterior limb longest, and you may overall comparable in dimensions to help you postcleithral process; postcleithral procedure deep and you will almost equilaterally triangular, coarsely ornamented specifically with each other ventral and you may ventrolateral corners lateral so you’re able to expressing fossa from pectoral spine. Within the ventral have a look at outward bulge out-of cleithrum during the transverse alignment with rear limitation off revealing fossa away from pectoral lower back. Mesocoracoid maybe not kept but raised body near dorsal side of coracoid shows its articulation webpages. Coracoid keel highly elevated proximally, stretching regarding halfway in order to pectoral symphysis; coracoid keel splits jointed horizontal branches off cleithrum and you may coracoid into equal halves; a couple parallel ridges run on the midline lateral branches out-of coracoid.
