A right quadratojugal missing the dorsal techniques (UCMP 195219; Figure 14e) is practically similar fit to that particular off Roentgen
Lots of explained pearly whites out-of Krzyzanowskisaurus hunti out-of UCMP 7308 already been out of field number CLC 36/8 (UCMP 139564 so you’re able to 139,575), apart from you to enamel regarding CLC (UCMP 139563). hunti, Heckert and you may Lucas ( 2002b ) described
fifty short square osteoderms in the exact same locality, assigning them to juveniles of one’s aetosaur Calyptosuchus wellesi. Given that noted from the Irmis, Parker, et al. ( 2007 ), these osteoderms (Rates 14i, j) is actually identical of those of Roentgen. callenderi. The specimens possess an elevated anterior pub and you may faintly incised extensively separated rounded pitting having a haphazard plan, a characteristics condition consolidation if not novel in order to Roentgen. callenderi. In accordance with the relevant and you will articulated specimens off R. callenderi from PEFO, the former is paramedian osteoderms from the rear cervical, dorsal, and you will anterior caudal regions of one’s body, whereas aforementioned morphology belongs to the a great deal more distal caudal part of one’s armour carapace. Some of the osteoderms explained by Heckert and you will Lucas ( 2002b ) contain the same industry matter while the Krzyzanowskisaurus hunti pearly whites, CLC thirty six/8.
From inside the examining uncatalogued issue out-of area UCMP 7308, Irmis, Parker, et al. ( 2007 ) as well as known a couple of cranial issues referable so you can Revueltosaurus out of community town CLC thirty-six/8, a nearly over kept squamosal (UCMP 165205; Contour 14g) (wrongly indexed since a right squamosal in Irmis, Parker, ainsi que al., 2007 ), and a partial quadrate (UCMP 165206; Figure 14f). The brand new cougar life nedir squamosal (UCMP 165205) are just like a similar element maintained regarding PEFO Roentgen. callenderi specimens; it’s triradiate, that have more substantial anterior process that broadens anteriorly, and you will quick however, line of posterodorsal and posteroventral procedure. Eg Roentgen. callenderi, this new dorsolateral epidermis was sculptured; so it sculpturing is actually bounded medially from the a distinct ridge one to models the newest lateral line of the supratemporal fossa. No matter if nearly the same as aetosaurs, each other UCMP 165205 and Roentgen. callenderi squamosals is proportionally large and you may shorter versus exact same function inside the aetosaurs (elizabeth.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Quick, 2002 ; Sulej, 2010 ). This new remote partial quadrate (UCMP 165206) can’t be formally described Revueltosaurus once the quadrate of Roentgen. callenderi does not possess one autapomorphies, but it is the same in form and you may morphology to help you understood instances of your own factor in R. callenderi, and you will shares with this particular taxon an increased medial condyle and you will straight positioning. Conversely, aetosaur quadrates is based anteroventrally (elizabeth.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ).
Heckert and you may Lucas ( 2002b ) identified a couple of osteoderm morphotypes: those that try wide than simply enough time, which they interpreted given that paramedian osteoderms, and people who are more than broad, that they interpreted because the lateral osteoderms
Then study of uncatalogued thing from UCMP 7308 by the article authors has revealed more skeletal situation almost certainly referable so you can Krzyzanowskisaurus hunti (Data 14c–g), and all of however, one of these issues also are regarding community urban area CLC thirty-six/8 (truly the only difference is parietal UCMP 195227, regarding CLC –80). A nearly complete kept postorbital (UCMP 195217; Shape 14d) is virtually identical to that Roentgen. callenderi and you will is different from other archosauriforms (e.g., Nesbitt, 2011 : figs. 7, 8, 11), plus aetosaurs, during the possessing a fairly quick jugal process that was linked to the new squamosal procedure because of the a general internet from narrow, somewhat ornamented limbs. One or two anterior servings regarding leftover parietals (UCMP 195227 and you can 195228) are as opposed to this new apparently wider, flat updates of most archosaurs (e.grams., Nesbitt, 2011 : figs. 8, 11), and you will tell R. callenderi a thin straight profile that broadens quite for the front articular surface, features the lowest average ridge, and you will a thin, dorsally-extreme ridge into horizontal margin you to boundaries this new supratemporal fenestra (Profile 14c). callenderi, like the autapomorphic v-shaped articular position on jugal, although it lacks the new heavy ornamentation into lateral body regarding specimens of PEFO. The distal percentage of a beneficial humerus (UCMP 165207; Profile 14h) and two cervical spinal vertebrae (UCMP 195222) can not be formally labeled Revueltosaurus predicated on apomorphies, however they are identical to a similar facets away from R. callenderi plus don’t satisfy the morphology of almost every other archosauriform taxa recognized out of this web site (we.elizabeth., A great. geoffreyi and you may V. campi).
