4.dos Diagnosis

Aetosauriformes (Profile dos) is different from all other archosaur clades from inside the possessing next unique combination of character says (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this research): convex distal side of distal maxillary white teeth (shared with certain loricatans along with crocodylomorphs); circular and you will dense factors with the medial section of the posterior procedure for this new squamosal on the paroccipital processes (shared with Turfanosuchus dabanensis); diapophysis and you will parapophysis toward middle trunk vertebrae stretched with the stalks (shared with ornithischian dinosaurs, ornithosuchids, Elizabeth. okeeffeae, and you can crocodyliforms); distance was shorter than simply 80% of the amount of the fresh humerus (shared with Dinosauria, Protosuchus richardsoni, and you may Alligator mississippiensis); and you can presacral paramedian osteoderms was mediolaterally wider than just anteroposteriorly a lot of time (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, plus the archosauriform V. campi); horizontal osteoderms present during the carapace (shared with erpetosuchids, A. geoffreyi and aetosaurians).

Modified medical diagnosis

I ending the prognosis of your own genus is not renewable and you may restricted to the latest genus as to start with diagnosed from the See ( 1989 ) and you can amended from the Heckert ainsi que al., ( 2012 ) (find reason less than). callenderi in line with the holotype and introduced matter.

Revised diagnosis

R. callenderi and also the next novel combination of character says (autapomorphies ; ): maxillary white teeth well inset on lateral margin of one’s head (= buccal emargination) (distributed to ornithischian dinosaurs); haphazard patterning on the dorsal epidermis away from square paramedian osteoderms (as opposed to radial patterning; shared with T. coccinarum); skull length is higher than regarding the fresh femur (distributed to phytosaurs, proterochampsids, and you may pterosaurs) where in fact the femur try

61% the duration of the fresh new head; descending procedure of the fresh new nose fits towards an excellent concave retailer on the the fresh premaxilla (distributed to T. dabanensis); brief outside nares (restrict dimension

1/step 3 the size of the newest orbit anteroposterior length)*; posterior means of jugal matches to the a-v-formed slot in the quadratojugal*; strongly verticalized parabasisphenoid (basitubera try dorsal with the pterygoid procedure) (distributed to some loricatans); average pharangeal recess of your own parabasisphenoid separated because of the a strong straight ridge*; external skin of your own squamosal laterally displaced according to the quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you may Tarjadia ruthae); rear caudal osteoderms bonded for the a stronger pipe*; dorsal eminence of your own paramedian osteoderms offset laterally about osteoderm center; horizontal osteoderms that will be significantly oblong (in lieu of equant or nearly equant) (shared with erpetosuchids); expressing band of ventral osteoderms (distributed to aetosaurs, for example, S. robertsoni).

4.six Introduced specimens

It osteological description would depend primarily towards the: PEFO 33787, PEFO 33788, partial head; PEFO 33789, correct scapulocoracoid; PEFO 33819, two sacral centra; PEFO 33845, leftover posterior portion of the iliac knife; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, remaining and correct frontals; PEFO 33875, sacral centrum; PEFO 33876, partial proper ilium; PEFO 33892, right ilium; PEFO 33894, left ilium; PEFO 34056, limited proper ilium; PEFO 34269, limited bones and head; PEFO 34273, left tibia; PEFO 34274, kept maxilla and you can lacrimal; and PEFO 34561, nearly complete head and relevant skeleton; PEFO 34570, partial braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, nearly done head and you can relevant specimen; PEFO 36876, limited skeleton; PEFO 42442/UWBM 116869, primarily done skeleton; PEFO 38609, over head; PEFO 33791, best ilium; and you may PEFO 33991, right ilium. More trick specimens include NMMNH P-16932, partial skeleton (Search et al., 2005 ), or any other NMMNH specimens listed in Heckert ( 2002 ). The newest single feature specimens listed above meets issue based in the partial relevant skeletons and thus was unambiguously assignable in order to Reveueltosaurus callenderi. The full selection of specimens described R. callenderi exists within the Research S1 and linear size of related specimens are provided from inside the Data S2. Look for three-dimensional models away from PEFO 34561 are offered into the Research S4.
