callenderi was indeed better-described (Heckert, 2002 ; Hunt, 1989 ; Check & Lucas, 1994 ; Padian, 1990 ). Having several tooth hit elements within-situ white teeth today allows a refinement from earlier work. Take a look ( 1989 ) try right during the recognize premaxillary teeth out of maxillary pearly whites. Yet ,, teeth like those about premaxilla (Numbers 4e, f), described as becoming symmetrical mesiodistally and you can lingually curved on apex, are also found in the prior portion of the dentary. Maxillary (Data 4g, h) and dentary white teeth (Shape 5d) in the ranking chatango taktikleri rear on the 3rd enamel are nearly symmetric mesiodistally, but both is lingually rounded from the top, labiolingually compacted, and also higher offered crowns. The design of your maxillary and you can dentary white teeth varies positionally in place of a great discernable pattern, perhaps linked to enamel replacement.
Tooth of R
The new anterior face of atlantal intercentrum try damaged out, but the rear 1 / 2 of this new ability try well preserved. When you look at the posterior look at (Figure 8c), new feature are subrectangular having slight dorsoventral constrictions along side midline. The fresh new atlantal intercentrum is concave dorsally where they articulates for the atlantal pleurocentrum. They articulates with the axial pleurocentrum having an apartment saddle-shaped body (Contour 8d). The new ventral facial skin of your atlantal intercentrum is actually excavated of the a great strong anxiety bordered by a-sharp prior ridge. The lateral epidermis is actually incised of the an intense dorsoventrally built sulcus you to shape anteriorly from the their dorsal the total amount. Both horizontal and ventral depression are not included in phytosaurs (e.g., Machaeroprosopus mccauleyi, PEFO 31219), where in fact the atlantal intercentrum try if not very similar to that Roentgen. callenderi.
5.six.1 Atlas-axis cutting-edge
The new atlantal pleurocentrum, intercentrum, and you can neurapophysis occur (Rates 8a–c). The prezygapophysis of your atlantal neurapophysis are a tiny anteriorly-projecting round projection (Contour 8a). In the phytosaurs (elizabeth.g., PEFO 31219) and you can crocodylomorphs (Brochu, 1992 ), this new prezygapophysis increases even more laterally. New postzygapophysis was much time and you will surge-particularly and you will systems posterodorsally. Stretching medially in the zygapophyses are a broad thin flange that models the fresh rooftop of your sensory tunnel.
This new atlantal pluerocentrum (Figure 8b) is actually crescentic when you look at the anterior and you can posterior viewpoints, in lieu of inside phytosaurs, in which it’s rectangular in the prior evaluate (age.grams., PEFO 31219). Both the anterior and posterior surfaces try convex, although prior articular face is actually some compliment and you may wider than the brand new rear articular face. This new posterior articular face features a shallow dorsoventrally popular sulcus that is additionally found in phytosaurs (e.g., PEFO 31219). The fresh dorsal facial skin of atlantal pleurocentrum are concave and mediolaterally doubly wider because anteroposteriorly long. Proportionally, the atlantal pleurocentrum off R. callenderi try anteroposteriorly quicker as compared to exact same factor in L. meadei (TMM 31185–97) and you may T. coccinarum (AMNH 7634), if not he could be much the same.
5.5 Postcrania Isolated and related postcranial points are all from the quarries within PFV 297 and PFV 414. An informed-preserved bones is the fact out of PEFO 34561, which will deliver the cause for the new repair (Figure seven) and you may malfunction, with other specimens supplementing this new description where detailed. 5.6 Axial bones
The fresh axial intercentrum is not identified from one specimen. New axial pleurocentrum (Shape 8d) off Roentgen. callenderi is roughly equant in dimensions. The brand new prior articular face is actually dorsally concave where they articulates having brand new atlantal points; ventral to that particular city the fresh new articular deal with try flat and hills posteroventrally in which it might articulate towards the axial intercentrum. The newest lateral corners of your own prior articular face of your axial pleurocentrum is offered since the margins abut towards the parapophyses. This new parapophyses features apartment articular counters, is actually raised towards line of pedestals, and you may face posterolaterally. Brand new diapophyses form a curved area one confronts posterolaterally and you may somewhat ventrally. The brand new lateral epidermis of one’s centrum possesses a deep fossa rear with the parapophysis. So it fossa try proportionally higher compared to L. meadei (TMM 31185-97) otherwise T. coccinarum (AMNH 7634), though the breadth associated with fossa transform as a result of ontogeny various other archosaurs (Irmis, 2007 ) which can be missing in a few aetosaurs (Desojo ainsi que al., 2012 ). New ventral facial skin of axis centrum and it has a-sharp average ventral keel. This really is absent in L. meadei.
