Ergo, we merely provide a modified analysis to have R

cuatro.2 Prognosis

Aetosauriformes (Figure dos) is different from other archosaur clades for the possessing next novel mix of reputation claims (Nesbitt, 2011 ; Butler mais aussi al., 2014 ; ; this research): convex distal edge of distal maxillary white teeth (distributed to certain loricatans plus crocodylomorphs); circular and you will heavy aspect on medial region of the rear procedure of the brand new squamosal on paroccipital procedure (shared with Turfanosuchus dabanensis); diapophysis and you will parapophysis into the center trunk vertebrae extended for the stalks (shared with ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you can crocodyliforms); radius is reduced than just 80% of your length of the fresh new humerus (distributed to Dinosauria, Protosuchus richardsoni, and Alligator mississippiensis); and presacral paramedian osteoderms was mediolaterally large than anteroposteriorly long (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, additionally the archosauriform V. campi); lateral osteoderms establish during most of the carapace (shared with erpetosuchids, A beneficial. geoffreyi and you may aetosaurians).

Revised prognosis

I finish that medical diagnosis of the genus isn’t renewable and restricted to the brand new genus while the to begin with recognized from the Check ( 1989 ) and you will revised of the Heckert ainsi que al., ( 2012 ) (discover need less than). callenderi according to the holotype and you can known procedure.

Modified analysis

R. callenderi and also the following book mix of profile states (autapomorphies ; ): maxillary white teeth really inset on lateral margin of one’s head (= buccal emargination) (shared with ornithischian dinosaurs); haphazard patterning towards dorsal facial skin out of square paramedian osteoderms (as opposed to radial patterning; shared with T. coccinarum); skull duration exceeds regarding brand new femur (shared with phytosaurs, proterochampsids, and you can pterosaurs) the spot where the femur try

61% the size of the latest skull; descending means of this new nasal suits toward a concave retailer towards the the new premaxilla (distributed to T. dabanensis); small exterior nares (limitation aspect

1/step three the size of this new orbit anteroposterior length)*; posterior procedure for jugal matches to the a-v-shaped slot regarding the quadratojugal*; strongly verticalized parabasisphenoid (basitubera are dorsal with the pterygoid processes) (shared with certain loricatans); average pharangeal recess of one’s parabasisphenoid separated because of the a strong straight ridge*; external epidermis of your own squamosal sideways displaced with respect to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and Tarjadia ruthae); posterior caudal osteoderms fused into a substantial tubing*; dorsal eminence of paramedian osteoderms offset sideways on the osteoderm center; horizontal osteoderms which can be significantly oblong (rather than equant otherwise nearly equant) (shared with erpetosuchids); articulating number of ventral osteoderms (shared with aetosaurs, including, S. robertsoni).

4.six Referred specimens

That it osteological malfunction depends generally on: PEFO 33787, PEFO 33788, limited head; PEFO 33789, right scapulocoracoid; PEFO 33819, one or two sacral centra; PEFO 33845, left posterior portion of the iliac knife; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, incomplete manus; PEFO 33874, left and you can best frontals; PEFO 33875, sacral centrum; PEFO 33876, partial proper ilium; PEFO 33892, proper ilium; PEFO 33894, leftover ilium; PEFO 34056, partial right ilium; PEFO 34269, partial bones and you will skull; PEFO 34273, kept tibia; PEFO 34274, left maxilla and you will lacrimal; and you can PEFO 34561, nearly complete skull and you can related bones; PEFO 34570, limited braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, nearly over head and you may relevant sample; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, mainly done skeleton; PEFO 38609, complete head; PEFO 33791, right ilium; and you may PEFO 33991, proper ilium. Even more key specimens include NMMNH P-16932, limited skeleton (Seem et al., 2005 ), and other NMMNH specimens placed in Heckert ( 2002 ). The fresh unmarried function specimens listed above meets factors found in the partial associated skeletons which means are unambiguously assignable to help you Reveueltosaurus callenderi. An aisle çevrimiçi entire set of specimens described Roentgen. callenderi exists inside the Analysis S1 and you can linear measurements of associated specimens are supplied in the Studies S2. See three-dimensional activities regarding PEFO 34561 are provided from inside the Study S4.
