New authors thank Petrified Forest National Playground Superintendents Lee Baiza, Cliff Spencer, and you may Brad Traver, Chiefs out-of Funding Management Karen Dorn and you can Tap Thompson, in addition to remainder of the park team to possess logistical service. Excavation functions is actually assisted of the datingranking.net/tr/edarling-inceleme Yasemin Tulu, Katie Brakora, Bruce Bailey, Franceska Sena, Meredith Fontana, Susan Drymala, Jake Tapaha, Ben Kligman, Emily Lessner, Pete Reser, additionally the late Vin Morgan. Thank-you so you’re able to Christian Sidor and you can Kelsey Abrams (UWBM) for preparing, photographs, and you will the means to access specimens from the its facilities. Most assistance worldwide is actually available with the new NPS Teens Preservation Corps in addition to Navajo Preservation Corps. Even more photographer and you will pictures were accomplished by Tyra Olstad. Dr. Tap Holroyd (UCMP) please given the means to access choices in her proper care. K. Ritterbush (University out-of Utah) amply considering usage of the lady petrographic microscope imaging program, in addition to osteoderm histological glides was in fact imaged because of the J. Hambleton. Reviews by the Hans-Dieter Sues, Julia B. Desojo, and you will Martin Ezcurra improved brand new manuscript. This can be Petrified Forest National Park Paleontological Share No. 74. The newest feedback conveyed here are those of your own experts and you will perform perhaps not show the state viewpoints of one’s You. S. Government.

One of those key early-branching pseudosuchians are Roentgen. callenderi, that has been to begin with called good putative ornithischian dinosaur centered on remote, however, apomorphic, pearly whites in the Bull Canyon Formation (Dockum Classification) out of east The latest Mexico, United states (Look, 1989 ). Next education (elizabeth.grams., Heckert, 2002 ; Take a look, 2001 ; Look & Lucas, 1994 ; Padian, 1990 ) known a lot more dental care specimens from other localities and you will continued to determine Roentgen. callenderi while the an unambiguous dinosaur having ornithischian synapomorphies. See ( 1994 , 2001 ) including detailed the current presence of a partial skeleton of an enthusiastic armored pseudosuchian (NMMNH P-16932) about method of locality regarding R. callenderi, he considered to be a definite taxon, but don’t formally explained. New discovery regarding associated skeletal issue also cranial matter within situ teeth regarding a good monodominant bonebed (sensu Eberth, Shannon, & Noland, 2007 ) regarding the Petrified Tree Person in the fresh Chinle Development within Petrified Tree Federal Playground (PEFO), Arizona, You, clearly presented you to Roentgen. callenderi was not good dinosaur, but rather an earlier-diverging pseudosuchian (Parker ainsi que al., 2005 ). According to you to definitely the brand new advice, See ainsi que al., ( 2005 ) known NMMNH P-16932 so you’re able to Roentgen. callenderi. As the dysfunction of these situation was short term, it is essential for a few grounds: (a) NMMNH P-16932 most certainly stands for Roentgen. callenderi since the sample comes with an effective dentigerous maxilla with teeth preserving Roentgen. callenderi apomorphies; (b) it’s of very close to the kind of area from Roentgen. callenderi, both geographically and you may stratigraphically (Check mais aussi al., 2005 ); and you can (c) NMMNH P-16932 try just like the fresh PEFO skeletal matter allotted to Roentgen. callenderi by Parker mais aussi al. ( 2005 ). New genus Revueltosaurus integrated a few most other species, “R”. hunti Heckert, 2002 , understood away from teeth and you will skeleton about all the way down Chinle Formation of Arizona and you will Utah minimizing Dockum Number of The new Mexico, and you will “R”. olseni (Hunt & Lucas, 1994 ), recognized out-of white teeth regarding Pekin Development regarding New york, You.

Besides the eponymous taxon, the only almost every other specimens out-of PFV 297 try fragmentary shuvosaurid skeleton (age.g., PEFO 34072) found ex-situ (Parker ainsi que al., 2005 ), and separated large, serrated white teeth. These include teeth identifiable in order to phytosaurs and a big mediolaterally compacted recurved enamel (crown length = 63.step three mm) that have a beneficial resorbed means that may portray a giant paracrocodylomorph (PEFO 41401). However, PFV 231 preserves a more varied assemblage and R. callenderi (age.g., PEFO 33791), the latest low-archosaur archosauriform Vancleavea campi (PEFO 33978), indeterminate brief metoposaurid temnospondyls (e.grams., PEFO 34081), shuvosaurids (elizabeth.grams., PEFO 33953), rauisuchids (sensu Nesbitt, 2011 ; e.grams., PEFO 33954), crocodylomorphs (age.grams., PEFO 34090), mystriosuchine leptosuchomorph phytosaurs (PEFO 33980), the aetosaur Typothorax coccinarum (elizabeth.grams., PEFO 33967), the early-diverging theropod dinosaur Chindesaurus bryansmalli (PEFO 33982), and you may a great coelophysoid theropod (elizabeth.grams., PEFO 33981; Parker et al., 2005 ; Parker & Irmis, 2005 ; Irmis, 2008 ; Parker & Barton, 2008 ; Parker & ).


The main cause of loss of they try unknown; not, monodominant bonebeds can be shaped from the unmarried disastrous situations where mix away from taxa, usually the outcome of long-identity attritional accumulation, will not occur (Eberth & Brinkman, 1997 ). Curiously, the individuals within PFV 297 and you can PFV 414 is actually alongside an identical size (Analysis S2) and presumably have been within equivalent ontogenetic amounts (however, select Griffin mais aussi al., 2020 having a discussion toward proportions and you can ontogenetic condition); not, PFV 231 consists of people of various versions including specimens bigger as opposed to those in the other one or two internet; like, the fresh new frontal of PEFO 41453 is actually

The matrix was constructed from inside the Mesquite v3.ten (Maddison & Maddison, 2019 ) and you will contains all in all, 444 emails getting 91 taxa. The new rhynchosaur Mesosuchus browni was applied given that outgroup so you’re able to supply the quintessential parsimonious trees (MPTs). The newest dataset are analyzed in the PAUP*4.0b10 (Swofford, 2002 ) using an excellent heuristic browse exposed to step 1,one hundred thousand arbitrary introduction replicates which have tree bisection and you will reconnection department trading. Emails 32, 52, 121, 137, 139, 156, 168, 188, 223, 247, 258, 269, 271, 291, 297, 314, 328, 356, 371, 399, 413, 430, and you may 432 (pick Nesbitt mais aussi al., 2020 having purchasing adjustment of fresh Nesbitt, 2011 dataset) was in fact purchased. Zero-size branches were folded when they lacked assistance under some of probably the most parsimonious reconstructions. A similar topology while the same amount of MPTs is retrieved when every characters are running unordered, in the event a new forest length is actually discovered. Bootstrap assistance is actually determined from,one hundred thousand replicates playing with an effective heuristic browse means with arbitrary taxon addition sequence and you will TBR department trading.
