A right quadratojugal destroyed the dorsal processes (UCMP 195219; Contour 14e) is virtually identical fit compared to that away from Roentgen

Several of discussed pearly whites away from Krzyzanowskisaurus hunti off UCMP 7308 been from profession count CLC thirty six/8 (UCMP 139564 to help you 139,575), apart from one to tooth out-of CLC (UCMP 139563). hunti, Heckert and you may Lucas ( 2002b ) demonstrated

50 brief square osteoderms in the same area, delegating them to juveniles of your own aetosaur Calyptosuchus wellesi. As noted by Irmis, Parker, et al. ( 2007 ), such osteoderms (Figures 14i, j) try indistinguishable regarding the ones from R. callenderi. Every specimens keeps an increasing anterior pub and you may faintly incised generally separated game pitting which have a haphazard plan, a nature condition combination if not book in order to R. callenderi. In line with the related and articulated specimens out-of Roentgen. callenderi of PEFO, the former are paramedian osteoderms on the rear cervical, dorsal, and you will anterior caudal areas of one’s body, whereas aforementioned morphology is one of the way more distal caudal region of the armour carapace. A few of the osteoderms revealed from the Heckert and you can Lucas ( 2002b ) contain the exact same career amount while the Krzyzanowskisaurus hunti teeth, CLC 36/8.

For the investigating uncatalogued point from locality UCMP 7308, Irmis, Parker, ainsi que al. ( 2007 ) along with known two cranial facets referable in order to Revueltosaurus out-of industry city CLC thirty-six/8, an about done remaining squamosal (UCMP 165205; Shape 14g) (erroneously detailed because the the right squamosal inside Irmis, Parker, mais aussi al., 2007 ), and you will a limited quadrate (UCMP 165206; Figure 14f). The latest squamosal (UCMP 165205) was identical to a comparable element managed on PEFO R. callenderi specimens; it is triradiate, having a much bigger prior process that broadens anteriorly, and you will short but distinct posterodorsal and you may posteroventral processes. Such Roentgen. callenderi, this new dorsolateral body is actually sculptured; that it sculpturing try bounded medially from the a distinct ridge you to definitely forms the horizontal border of your own supratemporal fossa. Regardless if much like aetosaurs, both UCMP 165205 and R. callenderi squamosals is proportionally broad and you will quicker than the exact same function within the aetosaurs (e.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ). The remote partial quadrate (UCMP 165206) can not be officially labeled Revueltosaurus since the quadrate off Roentgen. callenderi does not has actually one autapomorphies, however it is identical in shape and you can morphology in order to identified advice of your own consider R. callenderi, and you will offers with this specific taxon an enlarged medial condyle and you can vertical direction. Having said that, aetosaur quadrates is actually depending anteroventrally (elizabeth.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Quick, 2002 ; Sulej, 2010 ).

Heckert and you can Lucas ( 2002b ) recognized one or two osteoderm morphotypes: individuals who are wide than just enough time, which they interpreted as the paramedian osteoderms, and those that is actually longer than greater, that they translated while the lateral osteoderms

Next examination of uncatalogued issue regarding UCMP 7308 by article writers has revealed most skeletal topic more than likely referable in order to Krzyzanowskisaurus hunti (Rates 14c–g), as well as however, one of those issue are out-of field city CLC thirty-six/8 (truly the only exclusion is parietal UCMP 195227, of CLC –80). A very nearly complete kept postorbital (UCMP 195217; Shape 14d) is virtually same as regarding R. callenderi and you can is different from most other archosauriforms (age.grams., Nesbitt, 2011 : figs. seven, 8, 11), also aetosaurs, from inside the possessing a fairly brief jugal process that are linked to the fresh squamosal processes because of the a general online regarding narrow, some ornamented bones. Two anterior servings out-of left parietals (UCMP 195227 and 195228) are unlike this new relatively wide, apartment status of archosaurs (e.g., Nesbitt, 2011 : figs. 8, 11), and give R. callenderi a narrow straight figure one broadens some with the frontal articular skin, and has the lowest median ridge, and you can a thinner, dorsally-significant ridge to the lateral margin one to limits the new supratemporal fenestra (Contour 14c). callenderi, for instance the autapomorphic v-formed articular slot toward jugal, though it does not have the fresh new big ornamentation into the horizontal facial skin out-of specimens out-of PEFO. New distal part Siteye basД±n of an excellent humerus (UCMP 165207; Profile 14h) and two cervical spinal vertebrae (UCMP 195222) can not be formally labeled Revueltosaurus centered on apomorphies, however they are just like an equivalent issue of R. callenderi and don’t match the morphology regarding almost every other archosauriform taxa known using this website (i.age., An excellent. geoffreyi and you can V. campi).
