Also known as Pseudopalatus jablonskiae holotype site

Where: Arizona (34.9° N, 109.8° W: paleocoordinates 10.5° N, 48.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Sonsela Member (Chinle Formation), Norian (228.0 - 208.5 Ma)

• Basal Jim Camp Wash beds of the Sonsela Member of the Chinle Formation; "The medial unit [of the Sonsela Member] is called the Jim Camp Wash beds(Heckert and Lucas, 2002) and consists of strata that in the southern portion of the park had previously been assigned to the upper Petrified Forest Member (Billingsley, 1985; Long and Murry, 1995) and in the central portion of the park, to the lower Petrified Forest Member (Billingsley, 1985; Long and Murry, 1995). Historically, PFV 295 would have been considered to be low in the upper Petrified Forest Member (Long and Murry, 1995); however, the work of Heckert and Lucas(2002) and Woody (2003) suggests instead that it is low in the Sonsela Member, a few meters above the Rainbow Forest beds. This represents the stratigraphically lowest occurrence of Pseudopalatus in PEFO"

•"found 10.75 meters below a thick, cross-bedded brown sandstone that represents the Flattops One bed of Woody (2003) (Fig. 2). The skull is several meters above a whitish-gray cross-bedded sandstone that is correlative with the Rainbow Forest beds"

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithified, brown, gray, sandy, conglomeratic mudstone

Size class: macrofossils

Collected by Pat Jablonsky in 2002

Collection methods: quarrying,

• The skull was located in a path used by cultural researchers to access sites on the mesa top above the specimen locality and apparently the skull sustained damage from repeated human foot travel. The discoverer, Pat Jablonsky, brought the specimen to the attention of park staff who subsequently excavated it.
