The right quadratojugal forgotten its dorsal techniques (UCMP 195219; Profile 14e) is nearly the same in form to that particular away from Roentgen
Quite a few of discussed pearly whites out of Krzyzanowskisaurus hunti out-of UCMP 7308 started from field amount CLC thirty six/8 (UCMP 139564 so you’re able to 139,575), apart from that tooth of CLC (UCMP 139563). hunti, Heckert and Lucas ( 2002b ) discussed
fifty short rectangular osteoderms about same locality, assigning these to juveniles of the aetosaur Calyptosuchus wellesi. Since the indexed because of the Irmis, Parker, ainsi que al. ( 2007 ), this type of osteoderms (Rates 14i, j) try identical from those of Roentgen. callenderi. The specimens features an elevated anterior club and faintly incised generally spread circular pitting which have an arbitrary plan, a character county integration or even novel so you can R. callenderi. Based on the associated and you may articulated specimens away from R. callenderi of PEFO, the former is paramedian osteoderms on the posterior cervical, dorsal, and you will anterior caudal areas of your body, whereas the latter morphology is one of the a whole lot more distal caudal part of one’s armour carapace. A few of the osteoderms demonstrated because of the Heckert and you can Lucas ( 2002b ) contain the exact same job amount because Krzyzanowskisaurus hunti pearly whites, CLC thirty six/8.
From inside the exploring uncatalogued point away from area UCMP 7308, Irmis, Parker, ainsi que al. ( 2007 ) also understood a couple cranial issue referable so you’re able to Revueltosaurus away from job town CLC thirty-six/8, a virtually done remaining squamosal (UCMP 165205; Figure 14g) (wrongly indexed due to the fact the right squamosal within the Irmis, Parker, mais aussi al., bondage.com 2007 ), and you will a partial quadrate (UCMP 165206; Figure 14f). This new squamosal (UCMP 165205) try same as a comparable function maintained in the PEFO R. callenderi specimens; it’s triradiate, having a larger anterior procedure that broadens anteriorly, and you may brief but type of posterodorsal and you will posteroventral process. Such as for example R. callenderi, the fresh dorsolateral epidermis is actually sculptured; which sculpturing try bounded medially by a distinct ridge that forms new horizontal boundary of one’s supratemporal fossa. Whether or not much like aetosaurs, both UCMP 165205 and you can R. callenderi squamosals was proportionally wide and you can shorter compared to same element in the aetosaurs (e.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ). The isolated partial quadrate (UCMP 165206) can not be officially known Revueltosaurus given that quadrate regarding Roentgen. callenderi cannot have one autapomorphies, but it is similar in shape and you may morphology to recognized instances of consider R. callenderi, and you will shares using this type of taxon an enlarged medial condyle and you will straight positioning. On the other hand, aetosaur quadrates try built anteroventrally (age.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Small, 2002 ; Sulej, 2010 ).
Heckert and you may Lucas ( 2002b ) identified two osteoderm morphotypes: those who is greater than just much time, which they interpreted as the paramedian osteoderms, and those that is actually longer than greater, which they translated as lateral osteoderms
Subsequent study of uncatalogued material off UCMP 7308 by article authors has revealed additional skeletal matter more than likely referable to Krzyzanowskisaurus hunti (Figures 14c–g), and all but one among them issues also are out of profession town CLC thirty six/8 (truly the only difference is parietal UCMP 195227, out-of CLC –80). A practically done kept postorbital (UCMP 195217; Profile 14d) is close to identical to that Roentgen. callenderi and you will is different from most other archosauriforms (age.grams., Nesbitt, 2011 : figs. 7, 8, 11), and aetosaurs, within the possessing a relatively brief jugal procedure that try connected to the fresh new squamosal techniques by a broad internet off thin, a little ornamented bone. One or two prior portions out of remaining parietals (UCMP 195227 and 195228) was as opposed to the apparently large, apartment status of most archosaurs (elizabeth.g., Nesbitt, 2011 : figs. 8, 11), and you may give R. callenderi a thin straight profile you to definitely broadens a little into front articular body, and has now a minimal average ridge, and you can a slimmer, dorsally-high ridge into lateral margin you to definitely boundaries the fresh new supratemporal fenestra (Profile 14c). callenderi, such as the autapomorphic v-formed articular slot with the jugal, though it does not have the newest big ornamentation toward lateral surface of specimens off PEFO. The fresh distal percentage of a good humerus (UCMP 165207; Profile 14h) and two cervical spinal vertebrae (UCMP 195222) can not be formally described Revueltosaurus according to apomorphies, however they are same as the same aspects of R. callenderi and do not satisfy the morphology from most other archosauriform taxa recognized from this site (we.age., A good. geoffreyi and you may V. campi).
