cuatro.dos Medical diagnosis

Aetosauriformes (Profile 2) differs from any kind of archosaur clades inside possessing the second unique blend of reputation says (Nesbitt, 2011 ; Butler ainsi que al., 2014 ; ; this study): convex distal edge of distal maxillary teeth (shared with specific loricatans also crocodylomorphs); circular and you may heavy element towards medial region of the posterior procedure for the newest squamosal into paroccipital processes (distributed to Turfanosuchus dabanensis); diapophysis and parapophysis towards center trunk spinal vertebrae lengthened to the stalks (shared with ornithischian dinosaurs, ornithosuchids, E. okeeffeae, and you will crocodyliforms); radius is less than just 80% of your own amount of the fresh humerus (shared with Dinosauria, Protosuchus richardsoni, and Alligator mississippiensis); and you will presacral paramedian osteoderms are mediolaterally wider than just anteroposteriorly long (distributed to Riojasuchus tenuisceps, protosuchid crocodyliforms, phytosaurs, in addition to archosauriform V. campi); lateral osteoderms present throughout all the carapace (shared with erpetosuchids, A great. geoffreyi and aetosaurians).

Revised analysis

We end that analysis of one’s genus isn’t alternative and limited to the fresh genus while the to begin with identified by Check ( 1989 ) and you can revised by Heckert mais aussi al., ( 2012 ) (come across cause less than). callenderi based on the holotype and introduced procedure.

Modified analysis

R. callenderi and it has the second novel blend of character says (autapomorphies ; ): maxillary white teeth better inset about horizontal margin of one’s skull (= buccal emargination) (distributed to ornithischian dinosaurs); haphazard patterning for the dorsal surface away from square paramedian osteoderms (in place of radial patterning; shared with T. coccinarum); skull length exceeds that new femur (shared with phytosaurs, proterochampsids, and you will pterosaurs) where in fact the femur was

61% the size of the fresh skull; descending procedure for this new nose fits to the good concave retailer toward the brand new premaxilla (shared with T. dabanensis); small external nares (limit aspect

1/step three the size of the new orbit anteroposterior duration)*; posterior process of jugal matches to the a v-designed slot on quadratojugal*; strongly verticalized parabasisphenoid (basitubera is actually dorsal toward pterygoid procedure) (distributed https://datingranking.net/tr/bdsm-inceleme/ to certain loricatans); median pharangeal recess of parabasisphenoid split by the a powerful straight ridge*; outside epidermis of squamosal laterally displaced depending on the quadrate (distributed to aetosaurs, Gracilisuchus stipanicicorum, and you will Tarjadia ruthae); posterior caudal osteoderms fused towards a substantial pipe*; dorsal eminence of paramedian osteoderms offset sideways from the osteoderm center; lateral osteoderms which might be significantly oblong (in the place of equant or nearly equant) (shared with erpetosuchids); revealing group of ventral osteoderms (distributed to aetosaurs, particularly, S. robertsoni).

4.six Referred specimens

So it osteological dysfunction depends primarily for the: PEFO 33787, PEFO 33788, limited skull; PEFO 33789, right scapulocoracoid; PEFO 33819, a couple sacral centra; PEFO 33845, leftover rear part of the iliac blade; PEFO 33847, fused gastralia; PEFO 33848, dorsal rib; PEFO 33861, cervical vertebra; PEFO 33870, partial manus; PEFO 33874, left and you may proper frontals; PEFO 33875, sacral centrum; PEFO 33876, partial best ilium; PEFO 33892, proper ilium; PEFO 33894, remaining ilium; PEFO 34056, partial right ilium; PEFO 34269, limited skeleton and you can skull; PEFO 34273, kept tibia; PEFO 34274, leftover maxilla and you can lacrimal; and you may PEFO 34561, almost complete head and related skeleton; PEFO 34570, partial braincase; PEFO 34833, articulated cervical spinal vertebrae; PEFO 36875, nearly done skull and you can related specimen; PEFO 36876, partial bones; PEFO 42442/UWBM 116869, mostly over skeleton; PEFO 38609, over head; PEFO 33791, right ilium; and you will PEFO 33991, right ilium. Additional key specimens include NMMNH P-16932, partial bones (Check et al., 2005 ), and other NMMNH specimens listed in Heckert ( 2002 ). Brand new unmarried element specimens mentioned above meets facets found in the partial associated skeletons and therefore try unambiguously assignable to Reveueltosaurus callenderi. A complete a number of specimens known Roentgen. callenderi emerges into the Data S1 and you will linear size of related specimens are given in the Data S2. Get a hold of three dimensional models out-of PEFO 34561 are given in Data S4.
