Ergo, i merely provide a revised analysis to possess Roentgen

4.dos Analysis

Aetosauriformes (Shape 2) is different from some other archosaur clades during the possessing next novel combination of character says (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this research): convex distal edge of distal maxillary white teeth (distributed to some loricatans along with crocodylomorphs); rounded and you can thicker element on medial section of the posterior process of new eurodate giriЕџ squamosal towards paroccipital procedure (shared with Turfanosuchus dabanensis); diapophysis and parapophysis towards middle trunk area spinal vertebrae stretched with the stalks (shared with ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you may crocodyliforms); radius is smaller than just 80% of your own period of this new humerus (shared with Dinosauria, Protosuchus richardsoni, and you may Alligator mississippiensis); and you may presacral paramedian osteoderms try mediolaterally broad than just anteroposteriorly much time (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, while the archosauriform V. campi); horizontal osteoderms present while in the all of the carapace (distributed to erpetosuchids, A great. geoffreyi and aetosaurians).

Modified prognosis

We finish your medical diagnosis of your own genus isn’t alternative and you may limited to this new genus as in the first place recognized because of the Search ( 1989 ) and you will revised by Heckert ainsi que al., ( 2012 ) (pick need lower than). callenderi according to research by the holotype and you will referred procedure.

Revised medical diagnosis

R. callenderi features the next novel blend of profile says (autapomorphies ; ): maxillary white teeth really inset in the lateral margin of the head (= buccal emargination) (distributed to ornithischian dinosaurs); random patterning into the dorsal epidermis away from rectangular paramedian osteoderms (rather than radial patterning; shared with T. coccinarum); head size exceeds that of the femur (distributed to phytosaurs, proterochampsids, and you will pterosaurs) where in actuality the femur try

61% the duration of this new head; descending procedure of the new nasal fits towards an excellent concave retailer for the this new premaxilla (distributed to T. dabanensis); brief exterior nares (limitation dimensions

1/3 the duration of the latest orbit anteroposterior duration)*; rear procedure of jugal matches to your a-v-shaped position on the quadratojugal*; strongly verticalized parabasisphenoid (basitubera was dorsal toward pterygoid techniques) (shared with particular loricatans); average pharangeal recess of the parabasisphenoid separated by a powerful straight ridge*; outside facial skin of the squamosal sideways displaced according to the quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); rear caudal osteoderms fused for the a powerful tubing*; dorsal eminence of one’s paramedian osteoderms counterbalance laterally throughout the osteoderm center; horizontal osteoderms that are markedly oblong (in the place of equant otherwise nearly equant) (shared with erpetosuchids); showing number of ventral osteoderms (distributed to aetosaurs, for example, S. robertsoni).

4.6 Called specimens

So it osteological description is based mostly to your: PEFO 33787, PEFO 33788, limited skull; PEFO 33789, best scapulocoracoid; PEFO 33819, a couple of sacral centra; PEFO 33845, leftover rear part of the iliac blade; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, unfinished manus; PEFO 33874, leftover and you will proper frontals; PEFO 33875, sacral centrum; PEFO 33876, limited proper ilium; PEFO 33892, proper ilium; PEFO 33894, kept ilium; PEFO 34056, partial correct ilium; PEFO 34269, limited bones and you may skull; PEFO 34273, remaining tibia; PEFO 34274, remaining maxilla and lacrimal; and you may PEFO 34561, almost done head and you can relevant bones; PEFO 34570, limited braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, almost over head and you can related specimen; PEFO 36876, partial skeleton; PEFO 42442/UWBM 116869, primarily done bones; PEFO 38609, over skull; PEFO 33791, correct ilium; and you can PEFO 33991, proper ilium. Even more secret specimens become NMMNH P-16932, partial skeleton (Take a look et al., 2005 ), and other NMMNH specimens listed in Heckert ( 2002 ). The new solitary ability specimens listed above match points based in the limited associated skeletons meaning that are unambiguously assignable so you can Reveueltosaurus callenderi. A complete a number of specimens regarded Roentgen. callenderi is offered within the Studies S1 and you can linear size of related specimens are supplied in the Data S2. Pick three dimensional activities from PEFO 34561 are offered in Studies S4.
