cuatro.dos Medical diagnosis
Aetosauriformes (Contour 2) differs from another archosaur clades within the possessing another book mix of character claims (Nesbitt, 2011 ; Butler et al., 2014 ; ; this research): convex distal edge of distal maxillary white teeth (distributed to some loricatans including crocodylomorphs); circular and you will heavy element into the medial area of the rear procedure for the fresh squamosal for the paroccipital procedure (distributed to Turfanosuchus dabanensis); diapophysis and you can parapophysis toward middle trunk backbone lengthened towards the stalks (distributed to ornithischian dinosaurs, ornithosuchids, Elizabeth. okeeffeae, and crocodyliforms); radius was less than just 80% of your own amount of this new humerus (shared with Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and you can presacral paramedian osteoderms was mediolaterally wider than anteroposteriorly a lot of time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, as well as the archosauriform V. campi); lateral osteoderms present while in the most of the carapace (distributed to erpetosuchids, An excellent. geoffreyi and you can aetosaurians).
Modified analysis
I conclude that the diagnosis of one’s genus is not green and you can restricted to the new genus since to begin with diagnosed of the Hunt ( 1989 ) and you may amended by the Heckert mais aussi al., ( 2012 ) (pick reasoning below). callenderi based on the holotype and called procedure.
Modified diagnosis
Roentgen. callenderi and has the next unique mixture of profile states (autapomorphies ; ): maxillary white teeth better inset in the horizontal margin of your head (= buccal emargination) (shared with ornithischian dinosaurs); arbitrary patterning on dorsal skin of rectangular paramedian osteoderms (in place of radial patterning; shared with T. coccinarum); skull size is higher than regarding brand new femur (shared with phytosaurs, proterochampsids, and you will pterosaurs) the spot where https://datingranking.net/tr/adam4adam-inceleme/ the femur is
61% along the fresh skull; descending process of the fresh nasal matches toward a concave outlet towards new premaxilla (shared with T. dabanensis); short external nares (limit measurement
1/step three the length of the fresh new orbit anteroposterior size)*; posterior means of jugal suits toward a-v-shaped position about quadratojugal*; firmly verticalized parabasisphenoid (basitubera try dorsal towards the pterygoid processes) (shared with some loricatans); median pharangeal recess of parabasisphenoid divided of the a strong straight ridge*; outside skin of your squamosal sideways displaced with regards to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you may Tarjadia ruthae); posterior caudal osteoderms fused for the a stronger tube*; dorsal eminence of your paramedian osteoderms offset sideways regarding osteoderm center; lateral osteoderms that are significantly oblong (as opposed to equant or almost equant) (shared with erpetosuchids); revealing band of ventral osteoderms (distributed to aetosaurs, such as for instance, S. robertsoni).
cuatro.six Known specimens
It osteological dysfunction is based mostly with the: PEFO 33787, PEFO 33788, partial head; PEFO 33789, best scapulocoracoid; PEFO 33819, two sacral centra; PEFO 33845, kept rear part of the iliac blade; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, kept and right frontals; PEFO 33875, sacral centrum; PEFO 33876, limited best ilium; PEFO 33892, correct ilium; PEFO 33894, left ilium; PEFO 34056, partial right ilium; PEFO 34269, partial bones and head; PEFO 34273, remaining tibia; PEFO 34274, remaining maxilla and you can lacrimal; and you may PEFO 34561, nearly done head and you can related skeleton; PEFO 34570, limited braincase; PEFO 34833, articulated cervical backbone; PEFO 36875, almost over skull and you may associated sample; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, generally over bones; PEFO 38609, complete skull; PEFO 33791, best ilium; and you can PEFO 33991, correct ilium. A lot more trick specimens tend to be NMMNH P-16932, partial skeleton (Appear et al., 2005 ), or any other NMMNH specimens placed in Heckert ( 2002 ). Brand new single feature specimens in the list above matches points found in the partial relevant skeletons for example try unambiguously assignable so you’re able to Reveueltosaurus callenderi. The full variety of specimens regarded R. callenderi is offered in Data S1 and you may linear sized related specimens are given inside the Study S2. Pick 3d designs off PEFO 34561 are offered into the Analysis S4.
