cuatro.2 Analysis
Aetosauriformes (Shape dos) differs from any kind of archosaur clades when you look at the possessing another book mixture of character claims (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this research): convex distal edge of distal maxillary white teeth (shared with some loricatans together with crocodylomorphs); rounded and you will thicker element to your medial side of the rear process of the fresh squamosal towards paroccipital processes (shared with Turfanosuchus dabanensis); diapophysis and you may parapophysis into center trunk area backbone lengthened into stalks (shared with ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and crocodyliforms); distance try less than simply 80% of the length of the fresh humerus (distributed to Dinosauria, Protosuchus richardsoni, and you will Alligator mississippiensis); and presacral paramedian osteoderms are mediolaterally large than simply anteroposteriorly enough time (shared with Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, additionally the archosauriform V. campi); lateral osteoderms expose during the every carapace (distributed to erpetosuchids, A good. geoffreyi and you will aetosaurians).
Changed medical diagnosis
I end your diagnosis of genus is not alternative and you may simply for the latest genus because to begin with detected by Take a look ( 1989 ) and you may revised because of the Heckert et al., ( 2012 ) (get www.datingranking.net/tr/christiandatingforfree-inceleme a hold of reasoning less than). callenderi in line with the holotype and you will referred thing.
Changed diagnosis
Roentgen. callenderi and it has the second novel blend of character states (autapomorphies ; ): maxillary pearly whites better inset regarding lateral margin of the head (= buccal emargination) (shared with ornithischian dinosaurs); arbitrary patterning on dorsal skin from rectangular paramedian osteoderms (as opposed to radial patterning; shared with T. coccinarum); skull length exceeds compared to the newest femur (distributed to phytosaurs, proterochampsids, and pterosaurs) the spot where the femur is actually
61% the length of this new head; descending means of brand new nose suits to your good concave outlet to your this new premaxilla (shared with T. dabanensis); small additional nares (restriction measurement
1/3 the duration of this new orbit anteroposterior length)*; rear procedure of jugal suits on a v-designed slot on quadratojugal*; highly verticalized parabasisphenoid (basitubera are dorsal with the pterygoid techniques) (shared with specific loricatans); average pharangeal recess of your own parabasisphenoid divided by the a robust vertical ridge*; additional body of your squamosal laterally displaced with regards to the quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); rear caudal osteoderms fused into the a strong pipe*; dorsal eminence of paramedian osteoderms offset sideways on osteoderm center; horizontal osteoderms which can be markedly oblong (in place of equant otherwise almost equant) (distributed to erpetosuchids); articulating gang of ventral osteoderms (shared with aetosaurs, eg, S. robertsoni).
cuatro.6 Introduced specimens
So it osteological description is based primarily towards: PEFO 33787, PEFO 33788, partial head; PEFO 33789, right scapulocoracoid; PEFO 33819, a few sacral centra; PEFO 33845, leftover rear portion of the iliac knife; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, unfinished manus; PEFO 33874, remaining and you may right frontals; PEFO 33875, sacral centrum; PEFO 33876, limited right ilium; PEFO 33892, right ilium; PEFO 33894, remaining ilium; PEFO 34056, limited correct ilium; PEFO 34269, limited skeleton and you may head; PEFO 34273, kept tibia; PEFO 34274, leftover maxilla and you can lacrimal; and PEFO 34561, almost over head and you will related skeleton; PEFO 34570, limited braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, almost complete skull and you can related specimen; PEFO 36876, limited bones; PEFO 42442/UWBM 116869, generally done bones; PEFO 38609, over head; PEFO 33791, right ilium; and PEFO 33991, best ilium. Additional secret specimens include NMMNH P-16932, partial bones (Look et al., 2005 ), and other NMMNH specimens listed in Heckert ( 2002 ). This new unmarried feature specimens in the above list match aspects found in the partial relevant skeletons meaning that is actually unambiguously assignable to Reveueltosaurus callenderi. A complete listing of specimens known Roentgen. callenderi exists when you look at the Studies S1 and linear sized related specimens are given within the Research S2. Find 3d models away from PEFO 34561 are given when you look at the Study S4.
