4.2 Analysis
Aetosauriformes (Shape dos) differs from every other archosaur clades into the possessing the second unique mixture of character states (Nesbitt, 2011 ; Butler et al., 2014 ; ; this research): convex distal side of distal maxillary white teeth (shared with particular loricatans and crocodylomorphs); circular and you will heavy factors towards medial section of the rear procedure of the fresh new squamosal to your paroccipital processes (distributed to Turfanosuchus dabanensis); diapophysis and you may parapophysis to your middle trunk backbone extended with the stalks (distributed to ornithischian dinosaurs, ornithosuchids, Elizabeth. okeeffeae, and you may crocodyliforms); radius try reduced than 80% of the period of brand new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you may Alligator mississippiensis); and you may presacral paramedian osteoderms is mediolaterally greater than just anteroposteriorly enough time (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, and also the archosauriform V. campi); horizontal osteoderms introduce throughout every carapace (distributed to erpetosuchids, A. geoffreyi and aetosaurians).
Changed medical diagnosis
I finish that the diagnosis of the genus is not green and you may limited by the newest genus once the to begin with recognized from the Search ( 1989 ) and revised by Heckert et al., ( 2012 ) (see reason lower than). callenderi according to research by the holotype and you can called thing.
Modified medical diagnosis
Roentgen. callenderi and also next book combination of profile says (autapomorphies ; ): maxillary white teeth really inset throughout the lateral margin of your head (= buccal emargination) (shared with ornithischian dinosaurs); arbitrary patterning on the dorsal skin of rectangular paramedian osteoderms (in place of radial patterning; distributed to T. coccinarum); skull duration exceeds that the fresh femur (distributed to phytosaurs, proterochampsids, and you can pterosaurs) where in fact the femur is
61% along the newest skull; descending means of the nose fits towards a good concave retailer into the new premaxilla (shared with T. dabanensis); quick outside nares (limitation measurement
1/3 the size of the latest orbit anteroposterior size)*; posterior process of jugal suits into the a v-molded position on quadratojugal*; strongly verticalized parabasisphenoid (basitubera was dorsal on pterygoid techniques) (distributed to particular loricatans); average pharangeal recess of your parabasisphenoid separated by the a strong straight ridge*; exterior body of one’s squamosal sideways displaced according to quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you may Tarjadia ruthae); posterior caudal osteoderms fused with the a good tubing*; dorsal eminence of the paramedian osteoderms offset sideways in the osteoderm center; lateral osteoderms which might be markedly oblong (unlike equant otherwise almost equant) (distributed to erpetosuchids); showing band of ventral osteoderms (shared with aetosaurs, like, S. robertsoni).
cuatro.6 Referred specimens
Which osteological dysfunction would depend fetlife generally to your: PEFO 33787, PEFO 33788, limited head; PEFO 33789, proper scapulocoracoid; PEFO 33819, a couple of sacral centra; PEFO 33845, leftover rear portion of the iliac blade; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, incomplete manus; PEFO 33874, leftover and you can proper frontals; PEFO 33875, sacral centrum; PEFO 33876, partial best ilium; PEFO 33892, best ilium; PEFO 33894, left ilium; PEFO 34056, limited best ilium; PEFO 34269, partial bones and you may skull; PEFO 34273, remaining tibia; PEFO 34274, remaining maxilla and you may lacrimal; and you will PEFO 34561, nearly complete head and you can related bones; PEFO 34570, limited braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, nearly complete head and relevant specimen; PEFO 36876, limited skeleton; PEFO 42442/UWBM 116869, generally done skeleton; PEFO 38609, over skull; PEFO 33791, proper ilium; and you can PEFO 33991, proper ilium. Most key specimens is NMMNH P-16932, limited skeleton (Search ainsi que al., 2005 ), and other NMMNH specimens placed in Heckert ( 2002 ). The fresh new unmarried ability specimens mentioned above meets factors based in the limited relevant skeletons which means is actually unambiguously assignable to help you Reveueltosaurus callenderi. An entire listing of specimens referred to R. callenderi is provided in Analysis S1 and you may linear measurements of related specimens are supplied within the Investigation S2. Come across three-dimensional activities from PEFO 34561 are supplied within the Studies S4.
