5.6.six Posterior caudal vertebrae

Chevron points occur but are quicker distinct than in the latest mid-caudal spinal vertebrae no collection of groove toward midline of ventral epidermis can be found. This new transverse techniques is short sideways, dorsoventrally hit bottom forecasts regarding the posterior 50 % of the base of the latest neural arch. The latest zygapophyses opportunity some not in the centrum deal with and generally are small tab-instance processespared for the earlier vertebral show brand new neural back is reduced so you’re able to a thin median ridge linking brand new prezygapophyses and postzygapophyses.

5.6.7 Ribs

Cervical and trunk ribs is identified regarding associated specimens and in bonebeds in the PFV 297 and PFV 414. An around done cervical rib out of PEFO 34561 was really-managed which is missing just its rear suggestion while the tuberculum (Contour 8o). Brand new anterior procedure for this new rib versions a bent projection and you may tapers posteriorly to make a slimmer process. In the prior and rear see, this new capitulum in addition to base of the tuberculum was split up by deep grooves. Inside medial evaluate, the new rear processes shape anterodorsally and models an effective ridge one to will get the brand new capitulum. Low fossae can be found on either side associated with ridge. The size of the newest rib is quick, are a comparable length since length of a beneficial cervical centrum.

Several anterior trunk area ribs are also maintained inside the PEFO 34561 (Contour 8p). All are destroyed this new distal half of the latest feature. New tuberculum are raised with the a beneficial pedestal that is oval inside the cross-section and you may well-separated in the capitulum. The newest capitulum try raised towards an elongate pedestal which is rounded from inside the cross-section and you may depending as much as 45° throughout the tuberculum.Read More »The new centra of one’s rear caudal spinal vertebrae (Profile 8n) try anteroposteriorly elongate and you may strongly amphicoelous
