“…All these features correspond to those that characterize the genus Tayassu, except the tooth crown morphology, which other authors (Gasparini et al, , 2014 have referred to as bunodont for all the species of Tayassu, Dicotyles, Catagonus, Brasiliochoerus and Parachoerus (teeth of Parachoerus wagneri are referred to as "zygodont, " which is bunodont with relatively high cuspids) (Gasparini et al, 2009(Gasparini et al, , 2013(Gasparini et al, , 2019Prothero and Grenader, 2012;Avilla et al, 2013;Parisi Dutra et al, 2017).…”

“…According to these authors, Waldochoerus has the following diagnostic characters: mandible short and sturdy; high placement of mandibular condyle; and forward placement of mandibular condyle. All of these features characterize both extant genera of peccaries, Tayassu and Dicotyles (Gasparini, 2007;Gasparini et al, , 2014Parisi Dutra et al, 2017). It is notable that mandibles in Dicotyles are smaller than those observed in Tayassu (see measurements in Gasparini, 2007;Gasparini et al, , 2014.…”

“…All these features characterize both extant genera of peccaries, Tayassu and Dicotyles (Gasparini, 2007;Gasparini et al, , 2014Parisi Dutra et al, 2017). It is noteworthy that the length of the postcanine diastema measured in this genus allows us to consider it as a short diastema (shorter than 50% and longer than 30% of the length of the toothrow; see Gasparini, 2007).…”

“…Besides that, a short postcanine diastema represents one of the characters that allow grouping it into Tayassuini. This clade is composed of the three living species, Dicotyles tajacu (collared peccary), Tayassu pecari (white-lipped peccary), and Parachoerus wagneri (Chacoan peccary), in addition to the extinct taxa Brasiliochoerus stenocephalus, Parachoerus carlesi, Catagonus metropolitanus, and Catagonus bonaerensis (Parisi Dutra et al, 2017).…”

The earliest record of North American mammals in South America is significant for constraining the timing of intercontinental faunal interchange. At present, the oldest securely dated remains of a North American terrestrial mammal in South America pertain to a late Miocene procyonid; a few other North American mammal groups are present in late Miocene and early Pliocene outcrops in South America, but most are not recorded until the late Pliocene or Pleistocene, after the complete emergence of the Panamanian Isthmus. This long-established pattern has recently been called into question by reports of a proboscidean, two tayassuids, and a dromomerycine cervoid in supposed late Miocene deposits of Peruvian Amazon. In this contribution, we analyze the taxonomic identities and stratigraphic provenances of the tayassuid and dromomerycine fossils in detail. We conclude that these specimens are not distinguishable from modern tayassuids (Tayassu pecari and Dicotyles tajacu) and cervids, and that previous taxonomic identifications are based on misinterpretation of characters or inadequate specimens. In addition, there is insufficient evidence to support a late Miocene age for these terrestrial cetartiodactyl fossils; the stratigraphic provenance of the specimens is highly dubious, and the fossils are likely Quaternary in age.

“…Outside of the Palmetto Fauna, the eastern record is represented by the Pipe Creek paleosinkhole of Indiana (Hh4) ( Farlow et al, 2001 ; Prothero & Sheets, 2013 ), the Mauville local fauna of Alabama (Hh2) ( Hulbert & Whitmore, 2006 ), and the Tyner Farm locality of Florida (late Hh1 to early Hh2) ( Hulbert & Whitmore, 2006 ; Hulbert, Morgan & Kerner, 2009a ). Specifically, the Tyner Farm and Mauville local faunas both chiefly exhibit Prosthennops serus ( Hulbert & Whitmore, 2006 ; Hulbert, Morgan & Kerner, 2009a ) whereas the Pipe Creek fauna is attributed by Prothero & Sheets (2013) to include Protherohyus brachydontus (= Catagonus brachydontus ; see Parisi Dutra et al. (2017) and Platygonus pollenae .…”

Two peccary species, Mylohyus elmorei and Prosthennops serus are described from the medium-bodied fauna of the Gray Fossil Site (GFS) of northeastern Tennessee. This site, recognized as an oak-hickory forest, is latest Hemphillian or earliest Blancan based on mammalian biochronology, with an estimated age of 4.9–4.5 Ma. The GFS represents the only site outside the Palmetto Fauna of Florida with M. elmorei, greatly expanding the species range north over 920 km, well into the Appalachian region. This is also the first Appalachian occurrence of the relatively widespread P. serus. Our understanding of intraspecific variation for both M. elmorei and P. serus is expanded due to morphological and proportional differences found in cranial and dental material from the GFS, Tyner Farm locality, Palmetto Fauna, and within the literature. The GFS M. elmorei material represents the most complete mandible and second cranium for the species, and preserve intraspecific variation in the length of the diastema, dental proportions, and the complexity of the cuspules of the hypoconulid complex. Similarly, mandibular material from the GFS for P. serus exhibited larger dentitions and a greater degree of robustness than currently recognized for the species.
