The right quadratojugal destroyed the dorsal techniques (UCMP 195219; Figure 14e) is virtually the same fit compared to that from Roentgen

Lots of discussed teeth out-of Krzyzanowskisaurus hunti away from UCMP 7308 already been out-of community matter CLC 36/8 (UCMP 139564 so you’re able to 139,575), with the exception of you to tooth out of CLC (UCMP 139563). hunti, Heckert and you will Lucas ( 2002b ) described

fifty small square osteoderms throughout the same area, assigning them to juveniles of the aetosaur Calyptosuchus wellesi. Because noted by the Irmis, Parker, ainsi que al. ( 2007 ), such osteoderms (Numbers 14i, j) is actually indistinguishable from that from R. callenderi. All of the specimens have an elevated prior pub and you can faintly incised extensively spread circular pitting having an arbitrary plan, a nature state integration otherwise book so you’re able to R. callenderi. In line with the related and articulated specimens out-of Roentgen. callenderi out of PEFO, the former was paramedian osteoderms on rear cervical, dorsal, and you can prior caudal areas of the body, whereas the latter morphology is one of the even more distal caudal area of armor carapace. Many of the osteoderms demonstrated of the Heckert and you may Lucas ( 2002b ) contain the same field amount as Krzyzanowskisaurus hunti white teeth, CLC 36/8.

During the exploring uncatalogued issue out of area UCMP 7308, Irmis, Parker, mais aussi al. ( 2007 ) plus understood one or two cranial elements referable in order to Revueltosaurus out of community city CLC thirty-six/8, a nearly done kept squamosal (UCMP 165205; Figure 14g) (mistakenly indexed once the a right squamosal when you look at the Irmis, Parker, mais aussi al., 2007 ), and a partial quadrate (UCMP 165206; Shape 14f). This new squamosal (UCMP 165205) try same as a similar feature managed in the PEFO R. callenderi specimens; it is triradiate, having a more impressive anterior procedure that broadens anteriorly, and short but collection of posterodorsal and posteroventral techniques. Like R. callenderi, brand new dorsolateral epidermis was sculptured; this sculpturing is actually bounded medially by the a definite ridge that variations new horizontal edge of the supratemporal fossa. Whether or not very similar to aetosaurs, each other UCMP 165205 and you may Roentgen. callenderi squamosals was proportionally wide and you will quicker than the same function inside aetosaurs (age.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ). The brand new separated partial quadrate (UCMP 165206) cannot be formally regarded Revueltosaurus given that quadrate from R. callenderi cannot provides any autapomorphies, but it is the same in shape and morphology so you can recognized instances of aspect in R. callenderi, and offers with this taxon an enlarged medial condyle and you will straight direction. In contrast, aetosaur quadrates is centered anteroventrally (age.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Brief, 2002 ; Sulej, 2010 ).

Heckert and you can Lucas ( 2002b ) recognized a few osteoderm morphotypes: individuals who are wider than long, which they translated because paramedian osteoderms, and those that is actually more than wider, which they translated while the horizontal osteoderms

Then study of uncatalogued material of UCMP 7308 from the experts indicates additional skeletal material likely referable in order to Krzyzanowskisaurus hunti (Figures 14c–g), as well as but one of them factors are also off industry urban area CLC thirty six/8 (truly the only exception to this rule was parietal UCMP 195227, out of CLC –80). An around done left postorbital (UCMP 195217; Figure 14d) is almost same as that of R. callenderi and is different from other archosauriforms (elizabeth.grams., Nesbitt, 2011 : figs. eight, 8, 11), along with aetosaurs, inside the possessing a relatively small jugal process that are associated with the fresh squamosal process by a standard websites away from narrow, somewhat ornamented limbs. A couple prior portions of leftover parietals (UCMP 195227 and you will 195228) try in place of the fresh new relatively large, flat condition of most archosaurs (elizabeth.grams., Nesbitt, 2011 : figs. 8, 11), and you may share with Roentgen. callenderi a slim straight contour one to broadens a little with the front articular facial skin, features a minimal median ridge, and you may a thin, dorsally-high ridge towards lateral margin one limits the fresh new supratemporal fenestra (Contour 14c). callenderi, for instance the autapomorphic v-designed articular slot into the jugal, although it does not have the brand new heavier ornamentation with the lateral skin from specimens out of PEFO. The latest distal part of a good humerus (UCMP 165207; Profile 14h) and two cervical vertebrae (UCMP 195222) cannot be formally described Revueltosaurus centered on apomorphies, but they are same as a similar issue out of Roentgen. callenderi and don’t match the morphology of most other archosauriform taxa recognized from this site (i.elizabeth., A good. geoffreyi and you will V. campi).
