Aetosauriformes (Contour 2) differs from all other archosaur clades when you look at the having the next novel mixture of character states (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this research): convex distal edge of distal maxillary pearly whites (distributed to some loricatans along with crocodylomorphs); circular and you can heavy element into the medial section of the rear means of brand new squamosal to the paroccipital procedure (distributed to Turfanosuchus dabanensis); diapophysis and you may parapophysis into the center trunk backbone extended into stalks (distributed to ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you may crocodyliforms); radius are shorter than just 80% of your duration of the new humerus (shared with Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and you may presacral paramedian osteoderms try mediolaterally wider than anteroposteriorly a lot of time (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, and also the archosauriform V. campi); lateral osteoderms expose while in the the carapace (distributed to erpetosuchids, A great. geoffreyi and aetosaurians).
Changed medical diagnosis
I end that analysis of your genus is not green and you will simply for new genus given that to begin with diagnosed by Have a look ( 1989 ) and you may revised of the Heckert ainsi que al., ( 2012 ) (find reason below). callenderi in accordance with the holotype and you can called material.
Changed medical diagnosis
R. callenderi and has now the following unique mixture of reputation claims (autapomorphies ; ): maxillary teeth better inset on horizontal margin of your own skull (= buccal emargination) (shared with ornithischian dinosaurs); haphazard patterning to the dorsal body off rectangular paramedian osteoderms (rather than radial patterning; distributed to T. coccinarum); head size is higher than regarding this new femur (distributed to phytosaurs, proterochampsids, and you will pterosaurs) in which the femur is actually
61% the size of the fresh new skull; descending procedure for the new nasal fits on a great concave retailer on the brand new premaxilla (shared with T. dabanensis); brief external nares (limitation dimension
1/3 the duration of new orbit anteroposterior size)*; posterior procedure for jugal suits on the a-v-formed slot on the quadratojugal*; highly verticalized parabasisphenoid (basitubera try dorsal towards pterygoid techniques) (shared with certain loricatans); average pharangeal recess of your own parabasisphenoid split by the an effective straight ridge*; exterior body of one’s squamosal sideways displaced according to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you may Tarjadia ruthae); posterior caudal osteoderms fused with the a stronger tubing*; dorsal eminence of the paramedian osteoderms counterbalance laterally about osteoderm center; lateral osteoderms which might be markedly oblong (unlike equant or almost equant) (shared with erpetosuchids); revealing number of ventral osteoderms (distributed to aetosaurs, adultfriendfinder app such as for example, S. robertsoni).
cuatro.6 Called specimens
So it osteological description would depend mainly on the: PEFO 33787, PEFO 33788, limited skull; PEFO 33789, correct scapulocoracoid; PEFO 33819, a couple of 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, unfinished manus; PEFO 33874, kept and you can proper frontals; PEFO 33875, sacral centrum; PEFO 33876, limited proper ilium; PEFO 33892, correct ilium; PEFO 33894, leftover ilium; PEFO 34056, limited right ilium; PEFO 34269, partial bones and you can head; PEFO 34273, kept tibia; PEFO 34274, left maxilla and lacrimal; and you may PEFO 34561, almost over skull and associated skeleton; PEFO 34570, partial braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, almost over head and associated specimen; PEFO 36876, partial skeleton; PEFO 42442/UWBM 116869, generally complete skeleton; PEFO 38609, done head; PEFO 33791, best ilium; and you will PEFO 33991, right ilium. A lot more trick specimens include NMMNH P-16932, partial skeleton (Hunt mais aussi al., 2005 ), or any other NMMNH specimens placed in Heckert ( 2002 ). The fresh single function specimens mentioned above matches issues based in the partial associated skeletons and thus is actually unambiguously assignable in order to Reveueltosaurus callenderi. An entire range of specimens regarded R. callenderi is provided from inside the Analysis S1 and you may linear measurements of relevant specimens are offered in Research S2. See 3d designs out-of PEFO 34561 are given during the Analysis S4.
