- 1 Cranial articulation from hyomandibula and additionally slender anterodorsal procedure abutting poor ridge for the sphenotic before hyomandibular part; much time, lightly rounded condyle expressing that have hyomandibular element of sphenotic and you may pterotic; and quick, vertically-truncate posterodorsal epidermis revealing with pterotic about hyomandibular aspect
- 2 Weberian advanced without popular mid-dorsal straight lamina; sensory arc-spine complex incompletely kept however, anteriorly projecting to make contact with supraoccipital and you will exoccipitals
Cranial articulation from hyomandibula and additionally slender anterodorsal procedure abutting poor ridge for the sphenotic before hyomandibular part; much time, lightly rounded condyle expressing that have hyomandibular element of sphenotic and you may pterotic; and quick, vertically-truncate posterodorsal epidermis revealing with pterotic about hyomandibular aspect
Articulation webpages for the basioccipital for ossified Baudelot’s ligament raised and you will rugose. Exoccipital weakly medical stitches having basioccipital, prootic, pterotic and you will epioccipital; contributing brief dorsal way to cranial articulation having Baudelot’s tendon; vagal foramen high, game, ventrally led, considering a straight through the prior side of basioccipital-Baudelot’s tendon combined. Baudelot’s tendon out-of supracleithrum ossified and hefty; round within the part medially close contact with basioccipital and you can exoccipital. Exoccipital and epioccipital forming clear posterolateral corner of braincase you to definitely vertically buttresses stretched cranial articulation away from pteroticsupracleithrum. Anterolateral deal with away from epioccipital concave and weakly sutured to help you pterotic. Rear stop out of pterotic side produced and you can stretched ventral to cranial articulation of supracleithrum. Ventral edge of supraoccipital rear techniques having strong average vertical keel.
Suspensorium ( Fig. 5k, l). Hyomandibula wide and you will strong, sutured so you can preopercle through lateroposterior flange, and metapterygoid through large prior process; anteriorly sutured and posteriorly synconchondrally jointed in order to quadrate. Horizontal face having low, oblique increase ranging from prior techniques and you may preopercular flange, marking connection restrict of interior bundles regarding adductor mandibulae muscles. Lowest crest for the medioposterior boundary ventral in order to pterotic articulation, otherwise no increased showing techniques or muscle origin crests dorsal so you can opercle condyle. Opercle condyle mainly based slightly more than midpoint towards the posterior en from facial canal situated on prior body out of adductor muscles crest at the number of opercle condyle; medial foramen off facial canal anteriorly discover a lot more than adductor arcus palatini crest. Medial face which have centrally located straight and you can crescentic adductor arcus palatini scar even more popular compared to modern P. hemioliopterus ( Fig. 5m) but is figure and you can placement similar.
Preopercle sutured to help you quadrate along with hyomandibula; lateral deal with shallowly concave creating fossa to own posterior areas of adductor mandibulae muscles; posterior margin elevated when you look at the a gentle curve and you will almost certainly with sensory tunnel however, zero discernable lateralis skin pores; zero proof of additional foramen getting symplectic canal, however, medial foramen out of symplectic canal expose ranging from quadrate and you may preopercle.
Quadrate horizontal face primarily shallowly concave; anteroventral blade broadly sutured so you can metapterygoid; mandibular condyle large and firmly bilobed flanking central seat, medial lobe out-of condyle braced by the straight buttress.
Weberian advanced without popular mid-dorsal straight lamina; sensory arc-spine complex incompletely kept however, anteriorly projecting to make contact with supraoccipital and you will exoccipitals
Prior vertebrae ( Fig. 3b). Basic centrum articulated so you can basioccipital and you will profoundly sutured to help you substance or Weberian advanced centrum (2-4). Aortic groove open collectively midventral range, flanked from the lowest parallel ridges with each other basic and you can compound centra; broken just before centrum regarding vertebra 5. Indistinct items of tripus and you will lower operating system suspensorium stay-in set; anterior limbs regarding transverse techniques fulfill compound centrum at right-angle, broad and you will thickened laterally, generally getting in touch with ventral articulation flange out of supracleithrum; vertebra 5 indeterminate.
Pectoral girdle ( Figs. 5 e, f roksa.pl Zaloguj siД™, g). Dorsal revealing process of cleithrum bifid, prior limb longest, and you can total comparable in size so you’re able to postcleithral process; postcleithral processes strong and you will nearly equilaterally triangular, coarsely ornamented especially with each other ventral and you can ventrolateral corners horizontal to revealing fossa of pectoral spine. When you look at the ventral consider external fat out-of cleithrum inside the transverse alignment with posterior maximum of articulating fossa away from pectoral lower back. Mesocoracoid not kept but raised surface near dorsal side of coracoid reveals the articulation website. Coracoid keel strongly raised proximally, extending from the midway to pectoral symphysis; coracoid keel divides jointed lateral limbs regarding cleithrum and you can coracoid on equal halves; two parallel ridges run with the midline lateral limbs out of coracoid.
