4.2 Analysis
Aetosauriformes (Figure dos) differs from another archosaur clades within the having next book blend of reputation says (Nesbitt, 2011 ; Butler mais aussi al., 2014 ; ; this study): convex distal edge of distal maxillary teeth (distributed to some loricatans as well as crocodylomorphs); game and dense part towards medial area of the posterior procedure of the fresh squamosal on the paroccipital techniques (shared with Turfanosuchus dabanensis); diapophysis and you will parapophysis into middle trunk area spinal vertebrae prolonged to the stalks (shared with ornithischian dinosaurs, ornithosuchids, E. okeeffeae, and you can crocodyliforms); distance are less than just 80% of your duration of this new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and you can presacral paramedian osteoderms is actually mediolaterally wider than anteroposteriorly long (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, in addition to archosauriform V. campi); horizontal osteoderms present throughout the all of the carapace (shared with erpetosuchids, A. geoffreyi and aetosaurians).
Modified prognosis
We ending that medical diagnosis of your own genus is not alternative and simply for the fresh genus as the to start with identified because of the Search ( 1989 ) and you can amended by the Heckert mais aussi al., ( 2012 ) (discover reasoning below). callenderi based on the holotype and called issue.
Modified diagnosis
Roentgen. callenderi and also the next unique mixture of character states (autapomorphies ; ): maxillary white teeth well inset in the lateral margin of your head (= buccal emargination) (shared with ornithischian dinosaurs); random patterning to your dorsal epidermis out-of rectangular paramedian osteoderms (as opposed to radial patterning; distributed to T. coccinarum); skull size is higher than compared to the newest femur (distributed to phytosaurs, proterochampsids, and pterosaurs) where in fact the femur are
61% along the brand new skull; descending means of the brand new nasal matches on the a concave outlet towards the this new premaxilla (shared with T. dabanensis); brief exterior nares (limitation dimensions
1/step three the duration of the new orbit anteroposterior length)*; rear process of jugal fits to the a-v-shaped position regarding the quadratojugal*; strongly verticalized parabasisphenoid (basitubera try dorsal into pterygoid processes) (shared with some loricatans); median pharangeal recess of your own parabasisphenoid separated because of the a powerful vertical ridge*; outside body of one’s squamosal sideways displaced with respect to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); rear caudal chatki hesap silme osteoderms bonded into a solid pipe*; dorsal eminence of paramedian osteoderms counterbalance laterally on the osteoderm center; horizontal osteoderms which can be markedly oblong (in the place of equant otherwise almost equant) (shared with erpetosuchids); revealing set of ventral osteoderms (distributed to aetosaurs, such as for example, S. robertsoni).
cuatro.6 Called specimens
So it osteological breakdown is based mainly with the: PEFO 33787, PEFO 33788, partial head; PEFO 33789, proper scapulocoracoid; PEFO 33819, one or two sacral centra; PEFO 33845, kept rear portion of the iliac blade; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, incomplete manus; PEFO 33874, remaining and best frontals; PEFO 33875, sacral centrum; PEFO 33876, partial right ilium; PEFO 33892, right ilium; PEFO 33894, leftover ilium; PEFO 34056, partial right ilium; PEFO 34269, partial bones and you can head; PEFO 34273, kept tibia; PEFO 34274, leftover maxilla and you can lacrimal; and PEFO 34561, nearly complete skull and you will related bones; PEFO 34570, limited braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, nearly done head and you will associated sample; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, primarily complete bones; PEFO 38609, done skull; PEFO 33791, right ilium; and you will PEFO 33991, right ilium. Most trick specimens is NMMNH P-16932, limited skeleton (Look ainsi que al., 2005 ), or other NMMNH specimens placed in Heckert ( 2002 ). This new solitary ability specimens in the above list meets issues found in the limited relevant skeletons for example was unambiguously assignable to help you Reveueltosaurus callenderi. An entire range of specimens labeled R. callenderi emerges during the Investigation S1 and you may linear measurements of relevant specimens are provided when you look at the Research S2. Come across 3d patterns out-of PEFO 34561 are supplied inside the Study S4.
