4.dos Medical diagnosis
Aetosauriformes (Figure 2) differs from various other archosaur clades inside the having next book blend of profile says (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this study): convex distal edge of distal maxillary pearly whites (distributed to particular loricatans as well as crocodylomorphs); rounded and you can thicker element towards medial region of the posterior procedure for brand new squamosal towards the paroccipital techniques (shared with Turfanosuchus dabanensis); diapophysis and parapophysis on the center trunk vertebrae expanded into stalks (distributed to ornithischian dinosaurs, ornithosuchids, Elizabeth. okeeffeae, and crocodyliforms); distance is actually smaller than simply 80% of your own amount of the latest humerus (shared with Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and you will presacral paramedian osteoderms is mediolaterally greater than anteroposteriorly much time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, as well as the archosauriform V. campi); lateral osteoderms present through the most of the carapace (distributed to erpetosuchids, Good. geoffreyi and aetosaurians).
Changed diagnosis
I ending your medical diagnosis of the genus is not alternative and you will limited by the fresh genus as in the first place diagnosed by the See ( 1989 ) and revised of the Heckert et al., ( 2012 ) (select reason lower than). callenderi in line with the holotype and you may referred issue.
Modified analysis
Roentgen. callenderi features the next novel mixture of reputation states (autapomorphies ; ): maxillary pearly whites really inset on the lateral margin of one’s head (= buccal emargination) (shared with ornithischian dinosaurs); random patterning toward dorsal surface out of rectangular paramedian osteoderms (rather than radial patterning; distributed to T. coccinarum); skull length exceeds regarding the femur (shared with phytosaurs, proterochampsids, and pterosaurs) where in fact the femur is actually
61% the duration of the newest head; descending procedure for this new nose matches into the an effective concave retailer towards the fresh new premaxilla (shared with T. dabanensis); small outside nares (maximum aspect
1/3 the duration of new orbit anteroposterior duration)*; posterior procedure for jugal matches with the a-v-designed slot regarding quadratojugal*; firmly verticalized parabasisphenoid (basitubera is actually dorsal toward pterygoid procedure) (shared with certain loricatans); median pharangeal recess of your own parabasisphenoid separated by an effective straight ridge*; additional skin of your squamosal laterally displaced with respect to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); posterior caudal osteoderms fused towards a solid pipe*; dorsal eminence of your paramedian osteoderms counterbalance laterally throughout the osteoderm center; lateral osteoderms that will be significantly oblong (in lieu of equant otherwise almost equant) (shared with erpetosuchids); revealing gang of ventral osteoderms (shared with aetosaurs, instance, S. robertsoni).
4.6 Referred specimens
It osteological breakdown depends mainly towards: PEFO 33787, PEFO 33788, limited skull; PEFO 33789, proper scapulocoracoid; PEFO 33819, two sacral centra; PEFO 33845, kept rear portion of the iliac knife; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, kept and you can correct frontals; PEFO 33875, sacral centrum; PEFO 33876, partial correct ilium; PEFO 33892, correct ilium; PEFO 33894 http://www.datingranking.net/tr/elite-singles-inceleme, leftover ilium; PEFO 34056, limited best ilium; PEFO 34269, limited bones and skull; PEFO 34273, kept tibia; PEFO 34274, left maxilla and you will lacrimal; and you may PEFO 34561, almost over skull and you will associated bones; PEFO 34570, partial braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, almost over skull and you can related specimen; PEFO 36876, partial skeleton; PEFO 42442/UWBM 116869, mostly over bones; PEFO 38609, done skull; PEFO 33791, best ilium; and you may PEFO 33991, best ilium. More secret specimens were NMMNH P-16932, limited skeleton (See ainsi que al., 2005 ), or other NMMNH specimens listed in Heckert ( 2002 ). Brand new single ability specimens in the list above matches aspects found in the partial related skeletons and thus are unambiguously assignable in order to Reveueltosaurus callenderi. An entire variety of specimens known Roentgen. callenderi emerges into the Data S1 and you will linear size of related specimens are provided inside the Study S2. Find three-dimensional models out-of PEFO 34561 are provided when you look at the Research S4.
