A right quadratojugal missing their dorsal process (UCMP 195219; Shape 14e) is virtually identical in form to that away from Roentgen
Nearly all revealed pearly whites out-of Krzyzanowskisaurus hunti out-of UCMP 7308 become from job matter CLC thirty-six/8 (UCMP 139564 in order to 139,575), apart from you to definitely enamel off CLC (UCMP 139563). hunti, Heckert and you may Lucas ( 2002b ) discussed
fifty brief rectangular osteoderms on the same area, assigning these to juveniles of your own aetosaur Calyptosuchus wellesi. As detailed of the Irmis, Parker, et al. ( 2007 ), these types of osteoderms (Figures 14i, j) are indistinguishable off that from Roentgen. callenderi. All of the specimens has actually an elevated anterior club and you can faintly incised widely spread rounded pitting that have a random plan, a nature condition integration if you don’t novel so you’re able to R. callenderi. In accordance with the associated and you can articulated specimens from Roentgen. callenderi out-of PEFO, the previous try paramedian osteoderms on the rear cervical, dorsal, and you can anterior caudal areas of you, while the latter morphology belongs to the so much more distal caudal area of the armor carapace. Certain osteoderms explained by the Heckert and you may Lucas ( 2002b ) hold the exact same job number as the Krzyzanowskisaurus hunti pearly whites, CLC thirty-six/8.
Within the investigating uncatalogued topic away from locality UCMP 7308, Irmis, Parker, ainsi que al. ( 2007 ) plus identified a couple of cranial points referable so you can Revueltosaurus out-of industry urban area CLC 36/8, a practically done leftover squamosal (UCMP 165205; Contour 14g) (incorrectly listed since the a right squamosal when you look at the Irmis, Parker, mais aussi al., 2007 ), and a limited quadrate (UCMP 165206; Profile 14f). The brand new squamosal (UCMP 165205) was same as an equivalent element managed in the PEFO R. callenderi equestrian singles nedir specimens; it is triradiate, with more substantial prior process that broadens anteriorly, and you will small however, distinct posterodorsal and you can posteroventral techniques. Such as for example Roentgen. callenderi, the new dorsolateral facial skin is sculptured; that it sculpturing is actually bounded medially because of the a definite ridge one versions brand new lateral border of one’s supratemporal fossa. Although nearly the same as aetosaurs, one another UCMP 165205 and you can R. callenderi squamosals is actually proportionally greater and less versus same function during the aetosaurs (age.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Small, 2002 ; Sulej, 2010 ). The fresh new isolated partial quadrate (UCMP 165206) cannot be formally referred to Revueltosaurus as the quadrate out-of Roentgen. callenderi does not provides any autapomorphies, but it is the same fit and you may morphology in order to understood advice of your consider R. callenderi, and shares with this taxon an increased medial condyle and you can vertical positioning. Having said that, aetosaur quadrates was centered anteroventrally (e.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Quick, 2002 ; Sulej, 2010 ).
Heckert and you may Lucas ( 2002b ) understood two osteoderm morphotypes: individuals who is actually greater than simply enough time, which they interpreted while the paramedian osteoderms, and people who try longer than greater, that they interpreted because the lateral osteoderms
Next examination of uncatalogued issue out of UCMP 7308 from the article writers has revealed most skeletal thing most likely referable to Krzyzanowskisaurus hunti (Figures 14c–g), and all however, one among these facets are away from community town CLC thirty-six/8 (the sole difference was parietal UCMP 195227, from CLC –80). An almost complete remaining postorbital (UCMP 195217; Shape 14d) is close to same as compared to R. callenderi and you can differs from other archosauriforms (elizabeth.grams., Nesbitt, 2011 : figs. eight, 8, 11), as well as aetosaurs, inside having a comparatively brief jugal procedure that is actually linked to the new squamosal techniques because of the a general net from thin, some ornamented limbs. Two prior portions of leftover parietals (UCMP 195227 and you will 195228) are instead of the relatively wider, flat standing of all archosaurs (elizabeth.grams., Nesbitt, 2011 : figs. 8, 11), and you may share with R. callenderi a slim upright figure you to broadens quite on frontal articular facial skin, features a reduced average ridge, and you can a slimmer, dorsally-significant ridge to the lateral margin that boundaries the newest supratemporal fenestra (Contour 14c). callenderi, for instance the autapomorphic v-shaped articular position towards jugal, although it does not have the brand new big ornamentation into the horizontal surface off specimens from PEFO. The latest distal portion of good humerus (UCMP 165207; Figure 14h) as well as 2 cervical backbone (UCMP 195222) cannot be formally known Revueltosaurus centered on apomorphies, but they are identical to a comparable factors regarding Roentgen. callenderi plus don’t fulfill the morphology regarding other archosauriform taxa recognized out of this website (i.e., A good. geoffreyi and you can V. campi).
