Basioccipital weakly sutured to exoccipital and you will prootic; vertebral-like joint with very first centrum
Cranial articulation away from hyomandibula also thinner anterodorsal process abutting weakened ridge on the sphenotic in front of hyomandibular element; enough time, softly round condyle showing with hyomandibular aspect of sphenotic and you will pterotic; in addition to short, vertically-truncate posterodorsal facial skin articulating having pterotic about hyomandibular aspect
Articulation webpages on the basioccipital getting ossified Baudelot’s tendon raised and you will rugose. Exoccipital weakly surgical stitches which have basioccipital, prootic, pterotic and epioccipital; contributing brief dorsal strategy to cranial articulation which have Baudelot’s ligament; vagal foramen higher, game, ventrally brought, predicated on a straight from prior side of basioccipital-Baudelot’s tendon combined. Baudelot’s ligament regarding supracleithrum ossified and you will heavier; bullet for the point medially near experience of basioccipital and you can exoccipital. Exoccipital and epioccipital creating clear posterolateral corner regarding braincase that vertically buttresses lengthened cranial articulation regarding pteroticsupracleithrum. Anterolateral deal with regarding epioccipital concave and you may weakly sutured so you’re able to pterotic. Rear prevent out of pterotic wing delivered and you may stretched ventral so you can cranial articulation off supracleithrum. Ventral edge of supraoccipital posterior process which have good average vertical keel.
Suspensorium ( Fig. 5k, l). Hyomandibula broad and you will strong, sutured to help you preopercle via lateroposterior flange, and you can metapterygoid through large prior procedure; anteriorly sutured and posteriorly synconchondrally jointed so you can quadrate. (more…)
