In identical regularity in which Heckert ( 2002 ) named and described “R”
A right quadratojugal forgotten its dorsal processes (UCMP 195219; Shape 14e) is nearly the same in form to that particular off Roentgen
A lot of described pearly whites away from Krzyzanowskisaurus hunti off UCMP 7308 started out-of field amount CLC 36/8 (UCMP 139564 so you can 139,575), apart from you to definitely tooth off CLC (UCMP 139563). hunti, Heckert and Lucas ( 2002b ) demonstrated
fifty small rectangular osteoderms on the same area, assigning them to juveniles of your own aetosaur Calyptosuchus wellesi. As the indexed by Irmis, Parker, ainsi que al. ( 2007 ), this type of osteoderms (Data 14i, j) are identical off that from R. callenderi. The specimens has actually an increasing prior bar and faintly incised commonly spaced circular pitting having an arbitrary arrangement, a character condition integration or even book in order to R. callenderi. Based on the associated and you will articulated specimens out of Roentgen. callenderi away from PEFO, the former is paramedian osteoderms on the posterior cervical, dorsal, and you will prior caudal aspects of you, while the second morphology belongs to the far more distal caudal region of your armor carapace. A few of the osteoderms revealed by Heckert and you may Lucas ( 2002b ) contain the same occupation count since the Krzyzanowskisaurus hunti pearly whites, CLC thirty six/8.
In the exploring uncatalogued issue out-of locality UCMP 7308, Irmis, Parker, ainsi que al. ( 2007 ) as well as identified several cranial points referable to help you Revueltosaurus off profession town CLC thirty-six/8, a nearly over left squamosal (UCMP 165205; Shape 14g) (erroneously listed due to the fact the right squamosal in the Irmis, Parker, ainsi que al., 2007 ), and you may a partial quadrate (UCMP 165206; Contour 14f). The new squamosal (UCMP 165205) was identical to a comparable feature maintained regarding the PEFO R. callenderi specimens; it is triradiate, having a larger anterior process that broadens anteriorly, and you may short but distinctive line of posterodorsal and you can posteroventral techniques. For example R. callenderi, brand new dorsolateral epidermis is sculptured; that it sculpturing was bounded medially by the a distinct ridge you to variations the newest horizontal boundary of your supratemporal fossa. Even in the event very similar to aetosaurs, both UCMP 165205 and R. callenderi squamosals is proportionally large and you may faster as compared to exact same ability within the aetosaurs (elizabeth.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Small, 2002 ; Sulej, 2010 ). The newest remote limited quadrate (UCMP 165206) can’t be formally referred to Revueltosaurus because the quadrate out-of Roentgen. callenderi doesn’t keeps one autapomorphies, however it is identical fit and you may morphology in order to understood examples of factor in Roentgen. callenderi, and you may offers with this taxon an expanded medial condyle and you can straight orientation. However, aetosaur quadrates are oriented anteroventrally (age.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ).
Heckert and you may Lucas ( 2002b ) identified a few osteoderm morphotypes: people who try large than enough time, which they interpreted once the paramedian osteoderms, and those that try longer than broad, which they interpreted since the horizontal osteoderms
After that examination of uncatalogued topic from UCMP 7308 by people has revealed a lot more skeletal material probably referable to help you Krzyzanowskisaurus hunti (Figures 14c–g), and all but one of these factors are away from industry area CLC thirty six/8 (the only exemption is actually parietal UCMP 195227, of CLC –80). A nearly over kept postorbital (UCMP 195217; Profile 14d) is virtually same as that Roentgen. callenderi and you will differs from almost every other archosauriforms (elizabeth.g., Nesbitt, 2011 : figs. 7, 8, 11), and additionally aetosaurs, in having a relatively short jugal procedure that is actually connected to the brand new squamosal process because of the an over-all websites off slim, somewhat ornamented bone. A couple of prior portions away from remaining parietals (UCMP 195227 and you can 195228) is in the place of the brand new relatively wider, apartment updates of archosaurs (age.grams., Nesbitt, 2011 : figs. 8, 11), and you may give Roentgen. callenderi a thin upright figure one broadens a little towards front articular body, and has the lowest median ridge, and a thin, dorsally-extreme ridge to the lateral margin one to limitations the newest supratemporal fenestra (Shape 14c). callenderi, including the autapomorphic v-molded articular slot on jugal, although it does not have the brand new big ornamentation on horizontal facial skin from specimens regarding PEFO. New distal portion of good humerus (UCMP 165207; Contour 14h) and two cervical spinal vertebrae (UCMP 195222) cannot be officially described Revueltosaurus based on apomorphies, however they are identical to an equivalent points out-of Roentgen. callenderi and don’t satisfy the morphology out-of other archosauriform taxa identified using this site (we.age., A beneficial. geoffreyi and you will V. campi).
