The new Chinle Creation during the PEFO became well-old of the large-precision U–Pb zircon age and magnetostratigraphy, proving that the entire formation in this area try Norian-Rhaetian in the many years (Kent ainsi que al., 2018 , 2019 ; Ramezani mais aussi al., 2011 ; Rasmussen et al., 2020 ). Roentgen. callenderi occurs in the fresh uppermost Blue Mesa Representative because of middle Petrified Forest Associate within PEFO, with a mathematical age range off

218.5–210 Ma (middle-late Norian; Rasmussen ainsi que al., 2020 ). There can be certain suspicion about period of the low area of one’s Sonsela Affiliate according to the ages model chosen (Rasmussen mais aussi al., 2020 ) but this doesn’t impact the age of the original or history situations from R. callenderi during the PEFO.

Numerous elements of Roentgen. callenderi was in fact gathered out-of PFV 297, ranging from busted isolated skeleton to partly articulated skeletons. , 2007 ). This new specimens have been most of the recovered from 1 opinions when you look at the an excellent greenish-grey mudstone (“bluish websites” out of Loughney et al., 2011 ) which is next to a funnel facies of your Coated Wilderness Sandstone step three (Parker mais aussi al., 2005 ), which most likely depict levee dumps about proximal portion of the floodplain (T. Demko, individual telecommunications, ). Almost every other vertebrate localities throughout the Petrified Forest Associate exist within similar drab-coloured beds that have been interpreted as symbolizing poorly strained paleosols during the quit station fill which were at the very least seasonally drinking water-saturated (Loughney mais aussi al., 2011 ; Therrien & Fastovsky, 2000 ). Monodominant assemblages commonly occur in wetland facies (e.grams., overbank wetland/marginal pool) having reduced transportation and you will reworking possible (Eberth ainsi que al., 2007 ), referring to similar to the interpretation of the depositional environment out-of “blue internet sites” of Loughney ainsi que al. ( 2011 ). The clear presence of fossil equisetalean plant life (e.g., PEFO 41412) brazilcupid from the quarry also supports it translation. For the many of specimens away from PFV 297 and you may PFV 414, the internal places of bone were permineralized of the calcite spar, and in many cases, the fresh skeleton are also overgrown by a thin calcite spar coating. Many issues possess experienced slight synthetic deformation and brittle deformation because the evidenced by fracturing and you may displacement inside the specimens from enough time skeleton. Otherwise body bone preservation is exquisite, preserving good exterior information (elizabeth.grams., muscle scars) in lot of specimens, particularly in PEFO 34561.

The original situation off PFV 297 are located in early 2004 and you can amassed mainly just like the facial skin “float” you to definitely eroded out from the fossiliferous views, that have one in-situ articulated specimen that have a partial skull (PEFO 33787). Counts off correct ilia, proper femora, and left frontals indicated new conservation away from no less than four anybody (Parker et al., 2005 ). After that excavation off in-situ specimens contains of numerous separated issues together with five related skeletons (PEFO 34269; PEFO 34561; PEFO 36875; PEFO 36876). PEFO 34561 stands for up to ninety% of people while offering all of the dysfunction considering lower than. PEFO 36875 and contains a whole and you will mainly articulated head as well given that a partly articulated postcranial skeleton. An enthusiastic articulated head (PEFO 38609) plus one skeleton was in fact obtained for the 2015 (PEFO 42442/UWBM 116869) away from PFV 414; PEFO 42442/UWBM 116869 preserves the fresh new vertebral line and you may carapace of your own trunk region for the limited articulation, in addition to a complete, however, hit bottom, head. Such skeletons are present while the relatively isolated density off bones off unmarried somebody e bedding airplane by the normally step 1–2 meters. Together all the procedure away from PFV 297 and you may PFV 414 means a minimum of several anyone based on femora counts. Mukherjee and you can Ray ( 2012 ) discussed a similar taphonomic form to own good rhynchosaur-ruled bonebed from the Higher Triassic Tiki Creation off India. As with the fresh new Indian assemblage, it is probable within PFV 297 and you may PFV 414, to your fine-grained sediments plus in-situ equisitaleans, you to definitely delicate-muscle decomposition in the shallow water depth and you can subsequent weathering techniques disarticulated the folks regarding R. callenderi. Such skeletons was afterwards exposed to limited dispersal from the low-energy fluvial agencies and in the end burial inside the floodplain dumps (Mukherjee & Ray, 2012 ). This new rareness out of small issue such as gastralia and chevrons into the or even nearly complete specimens, and also the presence away from isolated skull, girdle, and you may limb bones of the same taxon, supporting this second dispersal feel (Mukherjee & Beam, 2012 ).
