“…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).…”

“…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).…”

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.

“…Based on this separation from T. pecari, and taxonomic priority, Theimer and Keim (1998) referred to the collared peccary as Pecari tajacu, and this combination has been followed by many researchers (e.g., Gongora and Moran, 2005;Grubb, 2005;Woodburne et al, 2006;Hulbert et al, 2009;Taber et al, 2011;Fariña et al, 2013;Reyna-Hurtado et al, 2018), as well as current online databases, such as the Tree of Life Web Project (2006), Animal Diversity Web (Ingmarsson, 1999), and IUCN Red List of Threatened Species (Gongora et al, 2011). Others have continued to use Tayassu for both the white-lipped and collared peccaries (e.g., Eisenberg and Redford, 1999;Gasparini et al, 2014), or agreed with the generic split but continued to use Dicotyles instead of Pecari for the collared peccary (e.g., Harris and Li-Ping, 2007;Prothero, 2009). Ramírez-Pulido et al (2014) recently argued for a return to Dicotyles based on nomenclatural priority.…”

<i>Muknalia minima</i> from the Yucatán of Mexico is synonymous with the collared peccary, Pecari tajacu (Artiodactyla: Tayassuidae)

Ongoing investigation of peccary remains from fossiliferous deposits in the Yucatán resulted in re-examination of previously identified tayassuid fossils from the region. This included the recently described new genus and species of peccary, Muknalia minima, which is based on a dentary from Muknal Cave near Tulum, Quintana Roo, Mexico. Diagnostic characters of this taxon include a concave notch along the caudal edge of the ascending ramus and a ventrally directed angular process. Our assessment of the holotype indicates that these characteristics are not a reflection of the original morphology, but are instead the result of breakage and polishing of the posterior aspect of the dentary. Measurements and intact morphological features indicate the Muknal Cave specimen belongs to the extant collared peccary, Pecari tajacu.

“…Both genera (Tayassu and Pecari) have been found as subfossils in Holocene deposits in Peru, Argentina, Venezuela, Panamá and Brazil (Cartelle & Hartwig, 1996;Eisenberg et al, 1979;Gasparini et al, 2013;Leigh & Wright, 1990;Terborgh, 1990;Politis & Messineo, 2008).…”

“…The oldest record of Tayassu pecari dates from middle Pleistocene in South America; it has been recorded mainly in Argentina, with a few records in Brazil, Uruguay, and Colombia (Porta, 1969;Paula Couto, 1975, 1981Ubilla, 2004;Ubilla et al, 2004;Gasparini & Ubilla, 2011;Gasparini et al, 2013) (Figure 7). The presence of Tayassu from El Breal Orocual, which is probably late Pliocene -early Pleistocene, represents the oldest record of this taxon in South America.…”

-Tayassuidae is represented by three extant species whose distribution ranges from southwestern United States to north-central Argentina. As one of the North American immigrants that entered South America during the Great American Biotic Interchange, the oldest unquestionable record of the family dates to the middle Pliocene in Argentina. Intensive paleontological fi eldwork carried out in Venezuela resulted in many new localities containing vertebrate fossils remains. Among these sites, the fossil-rich tar pits and caves are particularly signifi cant. Dental remains of Tayassu pecari discovered in these sites are smaller than those described from other regions. The presence of Tayassu pecari in the ?late Pliocene Venezuelan locality represents the putative oldest record of this species in South America. A few specimens were identifi ed as Pecari tajacu. The Venezuelan tayassuid fossils document the presence of these two distinct North American immigrant lineages in northern South America, and provide information that improves our understanding of the distribution and diversity of the group in South America during the late Pliocene-early Holocene, following their entry into South American during the Great American Biotic Interchange.Key words: caves, Pecari tajacu, tar pits, Tayassu pecari, Plio-Pleistocene, Venezuela.RESUMO -A família Tayassuidae está representada atualmente por três espécies, cuja distribuição varia do sudoeste dos Estados Unidos ao centro-norte da Argentina. Como um dos imigrantes norte-americanos que entraram na América do Sul durante o Grande Intercâmbio Biótico Americano, o mais antigo registro inquestionável da família data do Plioceno médio na Argentina. Intensivo trabalho de campo realizado na Venezuela resultou em muitas novas localidades contendo restos de fósseis de vertebrados. Entre esses sítios, os poços de piche e cavernas, ricos em fósseis, são particularmente signifi cativos. Restos dentários de Tayassu pecari descobertos nesses locais são menores do que aqueles descritos de outras regiões. A presença de Tayassu pecari na localidade venezuelana do Plioceno fi nal representa o registro mais antigo dessa espécie na América do Sul. Alguns espécimes foram identifi cados como Pecari tajacu. Os fósseis taiassuídeos venezuelanos documentam a presença destas duas linhagens distintas de imigrantes norte-americanos no norte da América do Sul, e fornecem informações que melhora a nossa compreensão sobre a distribuição e diversidade do grupo na América do Sul durante o Plioceno fi nalHoloceno inicial, após a sua entrada nesse continente, durante o Grande Intercâmbio Biótico Americano.Palavras-chave: cavernas, Pecari tajacu, poços de piche, Tayassu pecari, Plio-Pleistocene, Venezuela.
