A right quadratojugal destroyed their dorsal techniques (UCMP 195219; Figure 14e) is nearly identical in form to this regarding Roentgen
Quite a few of explained pearly whites away from Krzyzanowskisaurus hunti out of UCMP 7308 come out-of occupation count CLC thirty six/8 (UCMP 139564 to help you 139,575), except for one tooth out of CLC (UCMP 139563). hunti, Heckert and you may Lucas ( 2002b ) explained
fifty small rectangular osteoderms regarding same area, delegating them to juveniles of aetosaur Calyptosuchus wellesi. While the noted by Irmis, Parker, ainsi que al. ( 2007 ), these types of osteoderms (Figures 14i, j) try identical of those of Roentgen. callenderi. All the specimens have a raised prior bar and you will faintly incised extensively spread round pitting with an arbitrary arrangement, a character state integration if you don’t book to Roentgen. callenderi. According to the relevant and articulated specimens out of Roentgen. callenderi from PEFO, the previous is actually paramedian osteoderms regarding the rear cervical, dorsal, and you can prior caudal aspects of you, while aforementioned morphology is one of the significantly more distal caudal area of the armour carapace. A number of the osteoderms revealed because of the Heckert and you can Lucas ( 2002b ) contain the same profession matter while the Krzyzanowskisaurus hunti teeth, CLC thirty six/8.
During the exploring uncatalogued matter out-of locality UCMP 7308, Irmis, Parker, mais aussi al. ( 2007 ) together with recognized a few cranial factors referable so you can Revueltosaurus from profession urban area CLC 36/8, a virtually complete leftover squamosal (UCMP 165205; Profile 14g) (mistakenly noted given that the right squamosal into the Irmis, Parker, et al., 2007 ), and you may a limited quadrate (UCMP 165206; Contour 14f). The squamosal (UCMP 165205) are identical to an identical element maintained regarding the PEFO Roentgen. callenderi specimens; it is triradiate, having a much bigger prior process that broadens anteriorly, and you will short but distinct posterodorsal and you may posteroventral process. Like Roentgen. callenderi, new dorsolateral body is actually sculptured; this sculpturing was bounded medially because of the a definite ridge you to variations brand new lateral edge of the supratemporal fossa. Even in the event nearly the same as aetosaurs, one another UCMP 165205 and R. callenderi squamosals is proportionally broad and quicker versus same ability in aetosaurs (elizabeth.grams., Desojo & Baez, 2007 ; Schoch, 2007 ; belirleyici köprü Small, 2002 ; Sulej, 2010 ). The newest separated partial quadrate (UCMP 165206) can not be officially referred to Revueltosaurus because the quadrate away from R. callenderi cannot keeps people autapomorphies, however it is the same in shape and you will morphology so you can understood advice of the element in Roentgen. callenderi, and you can shares with this particular taxon an increased medial condyle and you can straight positioning. On the other hand, aetosaur quadrates is actually situated anteroventrally (e.g., Desojo & Baez, 2007 ; Schoch, 2007 ; Short, 2002 ; Sulej, 2010 ).
Heckert and you will Lucas ( 2002b ) known several osteoderm morphotypes: those that try wider than enough time, that they interpreted since paramedian osteoderms, and people who is more than wide, that they translated given that lateral osteoderms
Then study of uncatalogued question away from UCMP 7308 because of the writers has revealed a lot more skeletal question probably referable in order to Krzyzanowskisaurus hunti (Numbers 14c–g), and all of but one of those points also are from career city CLC 36/8 (really the only exclusion try parietal UCMP 195227, regarding CLC –80). A practically over left postorbital (UCMP 195217; Contour 14d) is virtually just like compared to Roentgen. callenderi and you can differs from other archosauriforms (age.grams., Nesbitt, 2011 : figs. 7, 8, 11), in addition to aetosaurs, for the possessing a comparatively short jugal procedure that is actually connected to the fresh squamosal procedure by the a standard web away from thin, a bit ornamented limbs. A few anterior portions regarding left parietals (UCMP 195227 and 195228) try in lieu of the new seemingly wide, apartment status of all archosaurs (age.grams., Nesbitt, 2011 : figs. 8, 11), and you may give Roentgen. callenderi a slim upright shape one to broadens slightly toward frontal articular body, features a reduced average ridge, and you can a finer, dorsally-extreme ridge with the horizontal margin that borders the supratemporal fenestra (Profile 14c). callenderi, including the autapomorphic v-formed articular position to the jugal, although it lacks the fresh heavy ornamentation to your lateral surface regarding specimens away from PEFO. The distal part of an effective humerus (UCMP 165207; Shape 14h) as well as 2 cervical vertebrae (UCMP 195222) cannot be formally known Revueltosaurus centered on apomorphies, but they are same as a similar facets off Roentgen. callenderi and don’t match the morphology off almost every other archosauriform taxa identified out of this site (we.e., Good. geoffreyi and you will V. campi).
