Abstract Simojovelhyus pocitosense is based on a lower jaw fragment with three molars from the late Oligocene amber mine deposits near the village of Simojovel, Chiapas Province, Mexico. It is the oldest fossil mammal known from Central America. It was described by Ferrusquia-Villafranca in 2006 as a helohyid, a group of primitive artiodactyls known from the Bridgerian and Uintan (older than 49–42 Ma), yet it comes from early Arikareean deposits about 25–27 Ma, suggesting that it was a very… 
The first Mexican record of peccary footprints (Artiodactyla, Tayassuidae) from the late Cenozoic of Puebla: ichnotaxonomy and palaeobiological considerations
Abstract A set of artiodactyl footprints preserved in the Pie de Vaca Formation from the Plio-Pleistocene of south-central Puebla in central Mexico is formally described. The sample consists of five
Pakkokuhyus and Progenitohyus (Artiodactyla, Mammalia) from the Eocene of Southeast Asia are not Helohyidae: paleobiogeographical implications
TLDR
Reexamination of the few dental remains known for Pakkokuhyus and Progenitohyus indicates that they very probably do not belong to the Helohyidae but to the Dichobunidae, which suggests that the systematics of basal artiodactyls from Southeast Asia should be carefully reassessed.

THE FIRST PALEOGENE MAMMAL RECORD OF MIDDLE AMERICA: SIMOJOVELHYUS POCITOSENSE (HELOHYIDAE, ARTIODACTYLA)
Abstract Simojovelhyus pocitosense, gen. et sp. nov., is based on a mandibular fragment with m1–3 collected from an unnamed Late Oligocene formation, in an amber mine near Simojovel, in northwestern
Extinct Peccary “Cynorca” Occidentale (Tayassuidae, Tayassuinae) from the Miocene of Panama and Correlations to North America
TLDR
The presence of “C.” occidentale indicates an interval of uncertain duration within the early Hemingfordian to early Barstovian land mammal ages for the Centenario Fauna, between about 19 and 14.8 million years ago.

TLDR
It is suggested that progressive protoceratids may be seen as ecological analogues of the Bushbuck of South Africa, a forest-adapted browser, and their greater proclivity toward survival in tropical latitudes explains the importance of Protocer atidae in the Gulf Coastal Plain during the Miocene, and evident higher abundance of Paratoceras in Central America.
