cuatro.2 Analysis
Aetosauriformes (Profile dos) differs from all other archosaur clades during the having another book mixture of character claims (Nesbitt, 2011 ; Butler mais aussi al., 2014 ; ; this research): convex distal side of distal maxillary pearly whites (shared with some loricatans as well as crocodylomorphs); rounded and thicker aspect on medial region of the posterior procedure of brand new squamosal on the paroccipital procedure (distributed to Turfanosuchus dabanensis); diapophysis and you will parapophysis towards center trunk area spinal vertebrae longer with the stalks (shared with ornithischian dinosaurs, ornithosuchids, Age. okeeffeae, and you may crocodyliforms); distance is shorter than just 80% of your duration of brand new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you can Alligator mississippiensis); and you can presacral paramedian osteoderms try mediolaterally wider than simply anteroposteriorly much time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, and also the archosauriform V. campi); lateral osteoderms introduce throughout the all carapace (distributed to erpetosuchids, An excellent. geoffreyi coffee meets bagel mobil and aetosaurians).
Changed diagnosis
I stop your analysis of your own genus is not green and you will simply for the newest genus as to start with detected from the Appear ( 1989 ) and you can amended by the Heckert mais aussi al., ( 2012 ) (find need below). callenderi in accordance with the holotype and you will known question.
Modified analysis
R. callenderi and has now the following novel mix of profile claims (autapomorphies ; ): maxillary white teeth well inset in the lateral margin of the skull (= buccal emargination) (shared with ornithischian dinosaurs); arbitrary patterning on dorsal facial skin from rectangular paramedian osteoderms (in place of radial patterning; shared with T. coccinarum); head duration is higher than that the femur (shared with phytosaurs, proterochampsids, and you can pterosaurs) where in fact the femur try
61% the length of the brand new skull; descending process of the newest nasal matches into the an effective concave retailer towards new premaxilla (distributed to T. dabanensis); short exterior nares (restriction measurement
1/step three along the orbit anteroposterior duration)*; posterior process of jugal suits on the a-v-designed position regarding quadratojugal*; firmly verticalized parabasisphenoid (basitubera is actually dorsal toward pterygoid procedure) (distributed to certain loricatans); median pharangeal recess of the parabasisphenoid split up by the a powerful straight ridge*; exterior surface of one’s squamosal sideways displaced with respect to the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); rear caudal osteoderms fused on a good pipe*; dorsal eminence of your paramedian osteoderms offset laterally throughout the osteoderm center; lateral osteoderms that will be significantly oblong (instead of equant or almost equant) (shared with erpetosuchids); revealing gang of ventral osteoderms (shared with aetosaurs, like, S. robertsoni).
cuatro.6 Known specimens
That it osteological dysfunction would depend generally on: PEFO 33787, PEFO 33788, limited head; PEFO 33789, proper scapulocoracoid; PEFO 33819, several sacral centra; PEFO 33845, left rear 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 will correct frontals; PEFO 33875, sacral centrum; PEFO 33876, partial proper ilium; PEFO 33892, right ilium; PEFO 33894, kept ilium; PEFO 34056, partial best ilium; PEFO 34269, limited bones and head; PEFO 34273, leftover tibia; PEFO 34274, left maxilla and you can lacrimal; and you will PEFO 34561, nearly complete head and you will associated skeleton; PEFO 34570, partial braincase; PEFO 34833, articulated cervical vertebrae; PEFO 36875, almost over skull and you may relevant sample; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, mainly over bones; PEFO 38609, done skull; PEFO 33791, proper ilium; and you can PEFO 33991, right ilium. More secret specimens tend to be NMMNH P-16932, partial bones (Search et al., 2005 ), and other NMMNH specimens placed in Heckert ( 2002 ). The brand new solitary function specimens in the list above meets aspects found in the limited relevant skeletons and therefore try unambiguously assignable so you’re able to Reveueltosaurus callenderi. An entire a number of specimens labeled Roentgen. callenderi exists during the Analysis S1 and you can linear measurements of related specimens are offered inside Studies S2. See three dimensional activities from PEFO 34561 are provided in Study S4.
