5.six.eight Ribs

Cervical and you may trunk area ribs was identified regarding the related specimens and you will from inside the bonebeds during the PFV 297 and you can PFV 414. A very nearly done cervical rib of PEFO 34561 are really-preserved that is shed merely their rear suggestion and tuberculum (Profile 8o). The prior procedure of the newest rib versions a circular projection and tapers posteriorly to create a slimmer process. From inside the prior and you can posterior examine, the capitulum together with foot of the tuberculum try split up by the deep grooves.
