A diverse new primate fauna from middle Eocene fissure-fillings in southeastern China
We report the discovery of a fauna of primates from Eocene (˜45 Myr) deposits in China having a diversity greater than in European and North American localities of similar antiquity. From the many…

Fossils from the Tuscahoma Formation are described, documenting an anatomically primitive species of Teilhardina that is older than other North American and European primates and indicates that primates originally colonized North America near the base of the Paleocene–Eocene Thermal Maximum, but before an important fall in eustatic sea level.
Middle Eocene primate tarsals from China: implications for haplorhine evolution.
The anthropoid tarsals are morphologically transitional between omomyids (or primitive haplorhines) and extant telanthropoids, providing the first postcranial evidence for primates which bridge the prosimian-anthropoid gap.
Gliding behaviour and palaeoecology of the alleged primate family Paromomyidae (Mammalia, Dermoptera)

Newly discovered fossils representing the paromomyid genera Phenacolemur and Ignacius show that these animals share functionally important postcranial synapomorphies with extant Cynocephalus (the flying lemur), the only living member of the mammalian order Dermoptera.
Cranial Anatomy of Shoshonius and the Antiquity of Anthropoidea
Although most, if not all, modern systematists agree that the living anthropoid or simiiform primates constitute a natural, monophyletic assemblage, there is widespread disagreement over whether or not certain fossil forms should be included in this taxon Anthropoidea.
Earliest Complete Dentition of an Anthropoid Primate from the Late Middle Eocene of Shanxi Province, China
The complete lower dentition of a new species of the basal anthropoid genus Eosimias shows a combination of primitive and derived traits unknown in other living or fossil primates, supporting the anthropoid affinities of Eosimiidae.
The oldest known anthropoid postcranial fossils and the early evolution of higher primates
Foot bones of Eosimias from the same middle Eocene sites in China that yield abundant dental remains of this primate substantiate the anthropoid status of EOSimias and clarify the phylogenetic position of anthropoids with respect to other major primate clades.
Laonastes and the "Lazarus Effect" in Recent Mammals
It is shown that Laonastes is actually a surviving member of the otherwise extinct rodent family Diatomyidae, known from early Oligocene to late Miocene sites in Pakistan, India, Thailand, China, and Japan.
First skulls of the Early Eocene primate Shoshonius cooperi and the anthropoid-tarsier dichotomy
The anatomy of four skulls of the early Eocene omomyid Shoshonius cooperi — the first cranial material recovered for this genus—strongly suggests that ShOSHonius shares a more recent common ancestry with Tarsius than do either anthropoids or other Eocene Omomyids for which cranial anatomy is known.
