cuatro.dos Prognosis
Aetosauriformes (Profile dos) differs from any archosaur clades into the having the second unique mix of character claims (Nesbitt, 2011 ; Butler et al., 2014 ; ; this study): convex distal side of distal maxillary teeth (distributed to some loricatans and additionally crocodylomorphs); round and you can thick element towards medial region of the rear process of new squamosal with the paroccipital process (distributed to Turfanosuchus dabanensis); diapophysis and you can parapophysis on the middle trunk spinal vertebrae stretched towards stalks (distributed to ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you may crocodyliforms); distance was reduced than just 80% of one’s period of the newest humerus (shared with Dinosauria, Protosuchus richardsoni, and you will Alligator mississippiensis); and presacral paramedian osteoderms is mediolaterally greater than just anteroposteriorly much time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, in addition to archosauriform V. campi); horizontal osteoderms present through the the carapace (shared with erpetosuchids, An excellent. geoffreyi and aetosaurians).
Modified analysis
We conclude your analysis of your genus isn’t renewable and restricted to the newest genus while the in the first place identified because of the Seem ( 1989 ) and amended by the Heckert et al., ( 2012 ) (see cause lower than). callenderi based on the holotype and you may called matter.
Revised analysis
R. callenderi possesses another novel blend of character states (autapomorphies ; ): maxillary white teeth well inset on the lateral margin of the skull (= buccal emargination) (distributed to ornithischian dinosaurs); haphazard patterning toward dorsal surface out-of rectangular paramedian osteoderms (as opposed to radial patterning; distributed to T. coccinarum); skull duration is higher than that the brand new femur (distributed to phytosaurs, proterochampsids, and you may pterosaurs) the spot where the femur is actually
61% the size of the new skull; descending means of the latest nose suits on the a great concave retailer toward brand new premaxilla (distributed to T. dabanensis); brief exterior nares (restriction aspect
1/3 along this new orbit anteroposterior length)*; rear means of jugal matches into the a-v-designed slot regarding the quadratojugal*; highly verticalized parabasisphenoid (basitubera are dorsal toward pterygoid processes) (shared with particular loricatans); median pharangeal recess of the parabasisphenoid divided by the a robust straight ridge*; external epidermis of the squamosal sideways displaced according to quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you can Tarjadia ruthae); posterior caudal osteoderms fused into a powerful tubing*; dorsal eminence of paramedian osteoderms offset laterally from the osteoderm center; lateral osteoderms that are significantly oblong (in the place of equant otherwise almost equant) (shared with erpetosuchids); expressing selection of ventral osteoderms (shared with aetosaurs, instance, S. robertsoni).

cuatro.6 Referred specimens
That it osteological dysfunction depends mostly on the: PEFO 33787, PEFO 33788, partial skull; PEFO 33789, best scapulocoracoid; PEFO 33819, a couple of sacral centra; PEFO 33845, left rear part of the iliac knife; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, unfinished manus; PEFO 33874, leftover and you can best frontals; PEFO 33875, sacral centrum; PEFO 33876, limited right ilium; PEFO 33892, correct ilium; PEFO 33894, kept ilium; PEFO 34056, partial best ilium; PEFO 34269, partial skeleton and you will skull; PEFO 34273, leftover tibia; PEFO 34274, kept maxilla and you can lacrimal; and PEFO 34561, nearly complete head and you will relevant skeleton; PEFO 34570, limited braincase; PEFO 34833, articulated cervical backbone; PEFO 36875, nearly done head and you may related sample; PEFO 36876, partial skeleton; PEFO 42442/UWBM 116869, generally complete skeleton; PEFO 38609, over head; PEFO 33791, correct ilium; and PEFO 33991, right ilium. A lot more trick specimens were NMMNH P-16932, limited bones (Take a look mais aussi al., 2005 ), or any other NMMNH specimens placed in Heckert ( 2002 ). The solitary ability specimens in the above list fits points based in the partial relevant skeletons for example is unambiguously assignable so you can Reveueltosaurus callenderi. An entire range of specimens regarded R. callenderi exists for the Studies S1 and linear sized associated specimens are offered from inside the Study S2. Find three dimensional activities out-of PEFO 34561 are offered inside Studies S4.
