callenderi have been really-revealed (Heckert, 2002 ; Hunt, 1989 ; Appear & Lucas, 1994 ; Padian, 1990 ). Having multiple enamel affect facets with in-situ white teeth today lets a refinement out-of prior works blendr ne demek. Check ( 1989 ) is actually proper in the distinguishing premaxillary pearly whites regarding maxillary teeth. But really, teeth such as those regarding the premaxilla (Data 4e, f), described as getting symmetrical mesiodistally and lingually curved in the top, are also based in the anterior portion of the dentary. Maxillary (Figures 4g, h) and you can dentary white teeth (Figure 5d) when you look at the positions rear towards the 3rd enamel are practically symmetrical mesiodistally, however, possibly was lingually curved at apex, labiolingually compressed, as well as have higher stretched crowns. The form of the maxillary and dentary teeth varies positionally instead good discernable pattern, perhaps connected with tooth replacement for.

The teeth out-of Roentgen

The brand new anterior face of atlantal intercentrum is actually busted out, although posterior 1 / 2 of the fresh ability are well preserved. Within the posterior see (Figure 8c), the brand new ability are subrectangular having moderate dorsoventral constrictions across the midline. The fresh new atlantal intercentrum is actually concave dorsally in which it articulates for the atlantal pleurocentrum. They articulates towards the axial pleurocentrum which have a flat seat-molded skin (Profile 8d). This new ventral skin of the atlantal intercentrum try excavated by an excellent deep depression bordered by a-sharp anterior ridge. The latest horizontal epidermis was incised of the a deep dorsoventrally mainly based sulcus you to definitely curves anteriorly at the their dorsal the amount. The lateral and you may ventral despair commonly used in phytosaurs (age.grams., Machaeroprosopus mccauleyi, PEFO 31219), where in fact the atlantal intercentrum is otherwise nearly the same as compared to Roentgen. callenderi.

5.6.step 1 Atlas-axis state-of-the-art

The new atlantal pleurocentrum, intercentrum, and you can neurapophysis occur (Rates 8a–c). This new prezygapophysis of your own atlantal neurapophysis try a tiny anteriorly-projecting round projection (Profile 8a). From inside the phytosaurs (age.g., PEFO 31219) and you can crocodylomorphs (Brochu, 1992 ), the fresh new prezygapophysis grows far more laterally. The newest postzygapophysis is a lot of time and you can spike-such as for instance and you can plans posterodorsally. Stretching medially throughout the zygapophyses was an over-all narrow flange one models new roof of your own sensory canal.

The brand new atlantal pluerocentrum (Figure 8b) is crescentic inside the prior and you may posterior feedback, in place of from inside the phytosaurs, where it is rectangular in the anterior glance at (elizabeth.grams., PEFO 31219). Both the anterior and you will rear counters are convex, although the prior articular face is a bit flatter and you will greater than simply the fresh new rear articular deal with. Brand new rear articular deal with and contains a superficial dorsoventrally trending sulcus one to is also found in phytosaurs (e.grams., PEFO 31219). The new dorsal epidermis of atlantal pleurocentrum is actually concave and you can mediolaterally two times as wider since the anteroposteriorly long. Proportionally, the newest atlantal pleurocentrum away from Roentgen. callenderi was anteroposteriorly reduced as compared to exact same element in L. meadei (TMM 31185–97) and you may T. coccinarum (AMNH 7634), otherwise he is comparable.

5.5 Postcrania Separated and you will relevant postcranial facets are about quarries during the PFV 297 and you can PFV 414. An informed-preserved skeleton is the fact regarding PEFO 34561, which will provide the reason for the brand new reconstruction (Shape seven) and you can description, along with other specimens complementing the dysfunction in which indexed. 5.six Axial skeleton

The new axial intercentrum is not known out of any specimen. Brand new axial pleurocentrum (Figure 8d) regarding Roentgen. callenderi is approximately equant within the dimensions. The latest anterior articular deal with is dorsally concave where they articulates with the new atlantal elements; ventral compared to that urban area new articular face was flat and mountains posteroventrally in which it can articulate with the axial intercentrum. Brand new horizontal edges of prior articular deal with of your axial pleurocentrum is actually longer because margins abut into the parapophyses. Brand new parapophyses has actually apartment articular surfaces, are elevated towards distinctive line of pedestals, and you can deal with posterolaterally. The new diapophyses means a bent section you to definitely faces posterolaterally and you will somewhat ventrally. This new lateral epidermis of one’s centrum and has now an intense fossa rear with the parapophysis. Which fossa is actually proportionally better than in L. meadei (TMM 31185-97) or T. coccinarum (AMNH 7634), although the depth of the fossa change compliment of ontogeny various other archosaurs (Irmis, 2007 ) which is missing in certain aetosaurs (Desojo et al., 2012 ). The brand new ventral epidermis of your own axis centrum features a-sharp median ventral keel. This is exactly missing inside L. meadei.
