4.2 Diagnosis

Aetosauriformes (Figure 2) is different from other archosaur clades inside the possessing the second book combination of profile claims (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this research): convex distal edge of distal maxillary pearly whites (shared with some loricatans together with crocodylomorphs); round and you can dense factors into the medial section of the rear procedure of this new squamosal to your paroccipital processes (distributed to Turfanosuchus dabanensis); diapophysis and you can parapophysis toward middle trunk area backbone offered toward stalks (shared with ornithischian dinosaurs, ornithosuchids, E. okeeffeae, and you may crocodyliforms); radius is actually faster than just 80% of the amount of the brand new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and presacral paramedian osteoderms is actually mediolaterally large than anteroposteriorly a lot of time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, in addition to archosauriform V. campi); horizontal osteoderms introduce during the carapace (shared with erpetosuchids, Good. geoffreyi and you may aetosaurians).

Changed prognosis

We finish the prognosis of your genus is not green and you can limited by the new genus while the in the first place identified because of the Look ( 1989 ) and you may revised by the Heckert ainsi que al., ( 2012 ) (see cause lower than). callenderi in line with the holotype and you can introduced issue.

Changed analysis

Roentgen. callenderi and has another book blend of character claims (autapomorphies ; ): maxillary teeth really inset about lateral margin of one’s head (= buccal emargination) (distributed to ornithischian dinosaurs); random patterning toward dorsal surface regarding rectangular paramedian osteoderms (in lieu of radial patterning; distributed to T. coccinarum); head duration is higher than that the fresh femur (shared with phytosaurs, proterochampsids, and pterosaurs) where the femur is actually

61% the duration of the head; descending process of the fresh nose fits with the a good concave retailer with the the new premaxilla (distributed to T. dabanensis); small external nares (restriction dimensions

1/3 the length of new orbit anteroposterior duration)*; posterior process of jugal suits towards a v-formed slot about quadratojugal*; firmly verticalized parabasisphenoid (basitubera is actually dorsal on pterygoid processes) (shared with certain loricatans); median pharangeal recess of the parabasisphenoid split up because of the a strong vertical ridge*; additional epidermis of one’s squamosal sideways displaced according to quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you may Tarjadia ruthae); posterior caudal osteoderms bonded toward a substantial pipe*; dorsal eminence of one’s paramedian osteoderms counterbalance laterally on osteoderm center; horizontal osteoderms which can be markedly oblong (in the place of equant or almost equant) (distributed to erpetosuchids); revealing gang of ventral osteoderms (shared with aetosaurs, including, S. robertsoni).

4.six Referred specimens

Which osteological malfunction depends mostly on: PEFO 33787, PEFO 33788, limited head; PEFO 33789, best scapulocoracoid; PEFO 33819, one or two sacral centra; PEFO 33845, left posterior part of the iliac knife; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, left and you may best frontals; PEFO 33875, sacral centrum; PEFO 33876, partial proper ilium; PEFO 33892, proper ilium; PEFO 33894, leftover ilium; PEFO 34056, partial proper ilium; PEFO 34269, limited skeleton and you can head; PEFO 34273, leftover tibia; PEFO 34274, remaining maxilla and you may lacrimal; and PEFO 34561, almost done head and you can related bones; PEFO 34570, limited braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, almost done head and you will relevant sample; PEFO 36876, limited bones; PEFO 42442/UWBM 116869, mostly complete bones; PEFO 38609, complete skull; PEFO 33791, right ilium; and you will PEFO 33991, proper ilium. Additional key specimens become NMMNH P-16932, limited skeleton (Look mais aussi al., 2005 ), or other NMMNH specimens listed in Heckert ( 2002 ). The newest single ability specimens mentioned above matches issue based in the partial related skeletons and thus try unambiguously assignable to Reveueltosaurus callenderi. An entire variety of specimens referred to R. callenderi emerges in the Studies S1 and you can linear size of associated specimens are supplied for the Study S2. Select three dimensional patterns out-of PEFO 34561 are given into the Analysis S4.
