4.dos Prognosis

Aetosauriformes (Profile 2) differs from all other archosaur clades during the having the following unique mixture of character says (Nesbitt, 2011 ; Butler et al., 2014 ; ; this study): convex distal side of distal maxillary pearly whites (distributed to certain loricatans together with crocodylomorphs); circular and heavy facet into the medial section of the posterior process of the brand new squamosal into the paroccipital process (shared with Turfanosuchus dabanensis); diapophysis and you can parapophysis for the center trunk area backbone stretched on the stalks (shared with ornithischian dinosaurs, ornithosuchids, E. okeeffeae, and you may crocodyliforms); distance try shorter than 80% of one’s duration of brand new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you may Alligator mississippiensis); and presacral paramedian osteoderms is actually mediolaterally large than just anteroposteriorly long (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, together with archosauriform V. campi); lateral osteoderms introduce during the all of the carapace (shared with erpetosuchids, An effective. geoffreyi and you may aetosaurians).

Revised analysis

I finish that diagnosis of the genus isn’t sustainable and you can simply for brand new genus given that in the first place recognized from the Appear ( 1989 ) and you will revised by Heckert et al., ( 2012 ) (look for reason below). callenderi according to research by the holotype and you will introduced thing.

Revised diagnosis

R. callenderi and has the next unique blend of character says (autapomorphies ; ): maxillary pearly whites better inset regarding lateral margin of your own head (= buccal emargination) (distributed to ornithischian dinosaurs); arbitrary patterning toward dorsal body off square paramedian osteoderms (in place of radial patterning; distributed to T. coccinarum); head size is higher than compared to the fresh new femur (shared with phytosaurs, proterochampsids, and you will pterosaurs) where in actuality the femur is

61% the length of the brand new skull; descending means of the brand new nose suits on an excellent concave outlet into the brand new premaxilla (distributed to T. dabanensis); small outside nares (restrict aspect

1/step three the length of the newest orbit anteroposterior size)*; posterior procedure for jugal fits on the a v-shaped position on quadratojugal*; firmly verticalized parabasisphenoid (basitubera is actually dorsal on pterygoid techniques) (shared with specific loricatans); median pharangeal recess of the parabasisphenoid split up by a robust straight ridge*; exterior surface of squamosal sideways displaced depending on the quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you can Tarjadia ruthae); rear caudal osteoderms fused on the a good tube*; dorsal eminence of the paramedian osteoderms offset laterally on osteoderm center; horizontal osteoderms that are markedly oblong (in place of equant or nearly equant) (shared with erpetosuchids); showing band of ventral osteoderms (shared with aetosaurs, like, S. robertsoni).

cuatro.6 Introduced specimens

It osteological dysfunction depends primarily to your: PEFO 33787, PEFO 33788, limited head; PEFO 33789, correct scapulocoracoid; PEFO 33819, two sacral centra; PEFO 33845, left posterior portion of the iliac knife; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, unfinished manus; PEFO 33874, kept and you can correct frontals; PEFO 33875, sacral centrum; PEFO 33876, limited correct ilium; PEFO 33892, right ilium; PEFO 33894, remaining ilium; PEFO 34056, limited right ilium; PEFO 34269, limited skeleton and you will skull; PEFO 34273, remaining tibia; PEFO 34274, remaining maxilla and you may lacrimal; and you may PEFO 34561, nearly over head and you can associated skeleton; PEFO 34570, limited braincase; PEFO 34833, articulated cervical backbone; PEFO 36875, nearly done skull and associated sample; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, primarily over skeleton; PEFO 38609, done head; PEFO 33791, best ilium; and PEFO 33991, proper ilium. More key specimens is NMMNH P-16932, limited bones (Check ainsi que al., 2005 ), or any other NMMNH specimens listed in Heckert ( 2002 ). The fresh solitary feature specimens in the above list match elements found in the limited relevant skeletons which means that was unambiguously assignable to help you Reveueltosaurus callenderi. The full variety of specimens labeled R. callenderi emerges into the Data S1 and you may linear sized related specimens are supplied from inside the Research S2. Find 3d models regarding PEFO 34561 are provided during the Study S4.
