The right quadratojugal missing its dorsal procedure (UCMP 195219; Profile 14e) is practically identical in form to this off R
Many of demonstrated teeth from Krzyzanowskisaurus hunti from UCMP 7308 become of career amount CLC thirty-six/8 (UCMP 139564 to help you 139,575), apart from you to definitely tooth out-of CLC (UCMP 139563). hunti, Heckert and Lucas ( 2002b ) demonstrated
50 short rectangular osteoderms on the exact same area, delegating them to juveniles of your own aetosaur Calyptosuchus wellesi. While the noted because of the Irmis, Parker, mais aussi al. ( 2007 ), this type of osteoderms (Data 14i, j) is indistinguishable away from the ones from R. callenderi. The specimens has an elevated prior club and you may faintly incised extensively spaced circular pitting that have a random arrangement, a character condition consolidation if you don’t book so you can R. callenderi. Based on the associated and you can articulated specimens off R. callenderi off PEFO, the former is actually paramedian osteoderms regarding the rear cervical, dorsal, and anterior caudal aspects of your body, while the second morphology is one of the a great deal more distal caudal region of your own armor carapace. A few of the osteoderms described from the Heckert and you may Lucas ( 2002b ) contain the same field count as Krzyzanowskisaurus hunti teeth, CLC 36/8.
In the investigating uncatalogued topic regarding locality UCMP 7308, Irmis, Parker, mais aussi al. ( 2007 ) in addition to recognized two cranial elements referable so you’re able to Revueltosaurus out of industry urban area CLC thirty-six/8, an almost over left squamosal (UCMP 165205; Figure 14g) (erroneously listed since the the right squamosal within the Irmis, Parker, et al., 2007 ), and you may a partial quadrate (UCMP 165206; Profile 14f). The newest squamosal (UCMP 165205) try just like a comparable function maintained on the PEFO Roentgen. callenderi specimens; it’s triradiate, having a bigger anterior process that broadens anteriorly, and quick however, type of posterodorsal and you will posteroventral processes. Particularly R. callenderi, the fresh dorsolateral facial skin was sculptured; that it sculpturing is actually bounded medially from the a definite ridge you to models this new horizontal boundary of your supratemporal fossa. Even if nearly the same as aetosaurs, both UCMP 165205 and you can Roentgen. callenderi squamosals are proportionally large and you can less than the exact same function inside the aetosaurs (e.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; Small, 2002 ; Sulej, 2010 ). The remote limited quadrate (UCMP 165206) can not be officially labeled Revueltosaurus due to the fact quadrate away from Roentgen. callenderi does not enjoys one autapomorphies, but it’s identical in shape and you will morphology in order to known advice of your own element in R. callenderi, and you will shares using this type of taxon an enlarged medial condyle and you will straight orientation. In contrast, aetosaur quadrates is dependent anteroventrally (age.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ).
Heckert and you may Lucas ( 2002b ) understood a couple osteoderm morphotypes: those people that is wide than simply enough time, that they interpreted as paramedian osteoderms, and those that are more than wider, that they interpreted because horizontal osteoderms
Then study of uncatalogued issue of UCMP 7308 of the article writers indicates most skeletal thing more than likely referable so you’re able to Krzyzanowskisaurus hunti (Numbers 14c–g), and all sorts of however, one of them issues are also of community urban area CLC thirty-six/8 (the actual only real exception to this rule are parietal UCMP 195227, out of CLC –80). An around over kept postorbital (UCMP 195217; Contour 14d) is virtually identical to regarding Roentgen. callenderi and you can differs from other archosauriforms (e.grams., Nesbitt, 2011 : figs. seven, 8, 11), along with aetosaurs, in possessing a relatively brief jugal procedure that was associated with the latest squamosal techniques because of the a standard net out-of thin, slightly ornamented bone. Several prior servings out-of left parietals (UCMP 195227 and you may 195228) is in place of the newest relatively broad, flat position of most archosaurs (e.grams., Nesbitt, 2011 : figs. 8, 11), and you will give R. callenderi a narrow straight shape that broadens a little with the frontal articular surface, and contains a decreased median ridge, and a finer, dorsally-tall ridge on the lateral margin one boundaries the fresh new supratemporal fenestra (Shape 14c). callenderi, for instance the autapomorphic v-molded articular position to your jugal, although it lacks the brand new big ornamentation on lateral skin out of specimens out of PEFO. The fresh new distal portion of a beneficial humerus (UCMP 165207; Figure 14h) as well as 2 cervical vertebrae (UCMP 195222) can’t be formally described Revueltosaurus centered on apomorphies, however they are identical to a similar factors off R. callenderi and don’t fulfill the morphology regarding almost every other archosauriform taxa identified out of this site (i.age., A good. geoffreyi and V. campi).
