cuatro.2 Diagnosis

Aetosauriformes (Profile dos) differs from all other archosaur clades when you look at the having the next book mix of character says (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this study): convex distal side of distal maxillary pearly whites (distributed to particular loricatans and crocodylomorphs); rounded and you will heavy part into medial region of the posterior process of the new squamosal for the paroccipital process (shared with Turfanosuchus dabanensis); diapophysis and you can parapophysis to the center trunk vertebrae expanded with the stalks (distributed to ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you may crocodyliforms); distance is less than 80% of your own period of the humerus (shared with Dinosauria, Protosuchus richardsoni, and you will Alligator mississippiensis); and you can presacral paramedian osteoderms is actually mediolaterally broad than simply anteroposteriorly enough time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, additionally the archosauriform V. campi); horizontal osteoderms present during every carapace (distributed to erpetosuchids, A good. geoffreyi and you may aetosaurians).

Changed prognosis

I end that analysis of the genus isn’t green and you will simply for the fresh genus because to start with detected by Have a look ( 1989 ) and you can revised of the Heckert et al., ( 2012 ) (select reasoning less than). callenderi in line with the holotype and you may known point.

Revised diagnosis

Roentgen. callenderi features the second book blend of reputation claims (autapomorphies ; ): maxillary pearly whites well inset on horizontal margin of head (= buccal emargination) (distributed to ornithischian dinosaurs); arbitrary patterning towards the dorsal surface out-of square paramedian osteoderms (in place of radial patterning; distributed to T. coccinarum); head size is higher than that brand new femur (distributed to phytosaurs, proterochampsids, and you will pterosaurs) the spot where the femur is

61% the duration of this new head; descending procedure for the fresh nasal fits towards the a beneficial concave retailer to the new premaxilla (shared with T. dabanensis); brief external nares (limit dimension

1/3 the length of the latest orbit anteroposterior duration)*; rear procedure for jugal fits on the a v-shaped position about quadratojugal*; highly verticalized parabasisphenoid (basitubera try dorsal to your pterygoid techniques) (shared with some loricatans); median pharangeal recess of parabasisphenoid split by an effective straight ridge*; outside skin of squamosal laterally displaced depending on the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); rear caudal osteoderms bonded on a stronger tube*; dorsal eminence of your paramedian osteoderms counterbalance sideways from the osteoderm center; lateral osteoderms which might be markedly oblong (in lieu of equant otherwise nearly equant) (distributed to erpetosuchids); articulating band of ventral osteoderms (shared with aetosaurs, such as, S. robertsoni).

cuatro.6 Referred specimens

So it osteological breakdown depends generally towards the: PEFO 33787, PEFO 33788, partial skull; PEFO 33789, best scapulocoracoid; PEFO 33819, a couple sacral centra; PEFO 33845, remaining rear part of the iliac blade; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, left and you may correct frontals; PEFO 33875, sacral centrum; PEFO 33876, limited proper ilium; PEFO 33892, proper ilium; PEFO 33894, leftover ilium; PEFO 34056, limited proper ilium; PEFO 34269, partial skeleton and you can head; PEFO 34273, left tibia; PEFO 34274, left maxilla and you may lacrimal; and PEFO 34561, almost complete skull and you may associated skeleton; PEFO 34570, limited braincase; PEFO 34833, articulated cervical backbone; PEFO 36875, almost complete skull and you will related sample; PEFO 36876, limited bones; PEFO 42442/UWBM 116869, mostly complete skeleton; PEFO 38609, over head; PEFO 33791, correct ilium; and you may PEFO 33991, right ilium. Extra trick specimens include NMMNH P-16932, limited skeleton (Take a look ainsi que al., 2005 ), and other NMMNH specimens listed in Heckert ( 2002 ). New solitary feature specimens in the list above fits issues found in the limited associated skeletons and thus was unambiguously assignable to Reveueltosaurus callenderi. A full range of specimens known Roentgen. callenderi emerges when you look at the Study S1 and you may linear measurements of related specimens are given into the Investigation S2. Select three-dimensional designs from PEFO 34561 are offered in the Studies S4.
