4.2 Medical diagnosis

Aetosauriformes (Figure dos) is different from some other archosaur clades in having next novel mixture of profile states (Nesbitt, 2011 ; Butler mais aussi al., 2014 ; ; this research): convex distal edge of distal maxillary white teeth (distributed to particular loricatans including crocodylomorphs); round and you may thick aspect to your medial side of the rear procedure for this new squamosal to your paroccipital process (distributed to Turfanosuchus dabanensis); diapophysis and you can parapophysis towards middle trunk spinal vertebrae longer towards stalks (shared with ornithischian dinosaurs, ornithosuchids, Elizabeth. okeeffeae, and crocodyliforms); radius try quicker than just 80% of your own length of new humerus (distributed to Dinosauria, Protosuchus richardsoni, and you will Alligator mississippiensis); and you may presacral paramedian osteoderms was mediolaterally wide than simply anteroposteriorly enough time (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, while the archosauriform V. campi); horizontal osteoderms introduce through the all of the carapace (shared with erpetosuchids, An excellent. geoffreyi and you can aetosaurians).

Modified medical diagnosis

We ending the medical diagnosis of genus isn’t renewable and you can restricted to the fresh new genus since to begin with diagnosed from the Check ( 1989 ) and you may revised of the Heckert mais aussi al., ( 2012 ) (find reasoning lower than). callenderi according to research by the holotype and you will introduced point.

Modified medical diagnosis

R. callenderi and has now the second book blend of character claims (autapomorphies ; ): maxillary teeth better inset on the lateral margin of the head (= buccal emargination) (distributed to ornithischian dinosaurs); random patterning toward dorsal body out-of square paramedian osteoderms (unlike radial patterning; distributed to T. coccinarum); skull duration is higher than that the latest femur (distributed to phytosaurs, proterochampsids, and pterosaurs) where femur was

61% the duration of the new head; descending process of the nose suits for the good concave socket on the premaxilla (shared with T. dabanensis); quick outside nares (maximum aspect

1/3 the length of the brand new orbit anteroposterior size)*; rear procedure of jugal suits on the a-v-shaped slot https://datingranking.net/tr/caribbeancupid-inceleme/ on quadratojugal*; firmly verticalized parabasisphenoid (basitubera try dorsal on pterygoid procedure) (distributed to certain loricatans); median pharangeal recess of your own parabasisphenoid divided by the an effective vertical ridge*; outside surface of one’s squamosal laterally displaced according to quadrate (shared with aetosaurs, Gracilisuchus stipanicicorum, and Tarjadia ruthae); rear caudal osteoderms fused on the a good pipe*; dorsal eminence of one’s paramedian osteoderms counterbalance sideways on the osteoderm center; horizontal osteoderms which might be significantly oblong (unlike equant or nearly equant) (shared with erpetosuchids); expressing selection of ventral osteoderms (shared with aetosaurs, particularly, S. robertsoni).

cuatro.6 Referred specimens

This osteological description depends generally with the: PEFO 33787, PEFO 33788, limited head; PEFO 33789, correct scapulocoracoid; PEFO 33819, a few sacral centra; PEFO 33845, remaining posterior portion of the iliac knife; PEFO 33847, bonded gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, unfinished manus; PEFO 33874, left and you can proper frontals; PEFO 33875, sacral centrum; PEFO 33876, partial correct ilium; PEFO 33892, right ilium; PEFO 33894, leftover ilium; PEFO 34056, partial right ilium; PEFO 34269, limited bones and skull; PEFO 34273, remaining tibia; PEFO 34274, leftover maxilla and lacrimal; and you may PEFO 34561, almost complete skull and you can related skeleton; PEFO 34570, partial braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, nearly done head and you will associated sample; PEFO 36876, partial skeleton; PEFO 42442/UWBM 116869, primarily over skeleton; PEFO 38609, over skull; PEFO 33791, best ilium; and you can PEFO 33991, correct ilium. Extra secret specimens tend to be NMMNH P-16932, limited bones (Seem ainsi que al., 2005 ), and other NMMNH specimens placed in Heckert ( 2002 ). The latest unmarried function specimens in the list above suits issue based in the partial associated skeletons for example was unambiguously assignable in order to Reveueltosaurus callenderi. An entire variety of specimens labeled R. callenderi is provided into the Studies S1 and linear measurements of related specimens are provided for the Data S2. See three-dimensional patterns off PEFO 34561 are given when you look at the Analysis S4.
