Referred specimens —Partial dentary with m1, m2, JODA 301; partial molar, JODA 302; partial dentary with p2 and p3(?), JODA 2230; molar, JODA 2238; molar, JODA 2239; molar, JODA 2240; premolar, JODA 2241; premolar, JODA 2242; deciduous premolar, JODA 2244; partial molar, JODA 2245; partial molar, JODA 2246; p2, JODA 2324; premolar, JODA 2341; M3, JODA 2342; premolar, JODA 2349; premolar, JODA 2391. From JDNM-71: molar fragment, JODA 13946. From UCMP -884: m3, UCMP 1628.

Occurrence —JDNM-4*, JDNM-71, UCMP -884.

Remarks —These specimens can be attributed to Tayassuidae ; however, there is no locality information because they were collected by the Weatherfords or park rangers during the first years of JODA or are assigned to a general locality number. Therefore, it is unclear which formation they are from. The specimens are all too big to belong to “ Cynorca ,” as described above, but lack the diagnostic characters that would be required to assign them to another genus. They fall within the size range of Dyseohyus fricki Stock, 1937 and “ Prosthennops ” xiphidonticus Barbour, 1925 , two Barstovian species ( Wright 1998); however, they also fall within the size range of Hemphillian peccaries such as Platygonus oregonensis Colbert, 1938 , which is known from and common in the Rattlesnake Formation ( Merriam et al. 1925). A lower right m3, UCMP 1628, was collected from locality -884 (Mascall Misc. 2). It has an anteroposterior length of 16.48 mm and a transverse width of 10.87 mm, the same size as D. fricki , the locality information is minimal and it is unclear if the specimen was found in the Mascall Formation or the Rattlesnake Formation.

A small tayassuid molar fragment (JODA 13946) was collected at JDNM-71 Rock Creek locality from the lower Mascall unit, demonstrating the stratigraphic persistence of peccaries throughout the lower and middle units of the formation.
