Cynocephalid dermopterans (flying lemurs) are represented by only two living genera (Cynocephalus and Galeopterus), which inhabit tropical rainforests of South‐East Asia. Despite their very poor diversity and their limited distribution, dermopterans play a critical role in higher‐level eutherian phylogeny inasmuch as they represent together with Scandentia (tree‐shrew) the sister group of the Primates clade (Plesiadapiformes + Euprimates). However, unlike primates, for which the fossil record… 

Euarchontan affinity of Paleocene Afro-European adapisoriculid mammals and their origin in the late Cretaceous Deccan Traps of India

The first tarsal bones of adapisoriculid mammals are identified, indicating an arboreal mode of life with euarchontan affinity, and phylogenetic affinities suggest a paleobiogeographic scenario for the family with dispersal either via East Africa or across the Tethys area.

New postcrania of Deccanolestes from the Late Cretaceous of India and their bearing on the evolutionary and biogeographic history of euarchontan mammals

The tentative identification of Deccanolestes as a basal stem euarchontan suggests that (1) Placentalia began to diversify and Eu archonta originated before the Cretaceous–Tertiary boundary and (2) the Indian subcontinent, Eurasia, and Africa are more likely places of origin for EUarchonta than is North America.

New Cyriacotheriid Pantodonts (Mammalia, Pantodonta) from the Paleocene of Alberta, Canada, and the Relationships of Cyriacotheriidae

The results strengthen previous hypotheses regarding the pantodont affinities of the family, and suggest that the dermopteran-like features seen in the more derived Cyriacotherium were acquired convergently.

The head and neck muscles of the colugo Cynocephalus volans are described and compared with those of other mammals, either dissected by me or described in the literature, and it is indicated that the plesiomorphic condition for euarchontans as well as for primates is more similar to that found in extant tree‐shrews than in extant colugos.

New fossil evidence of the early diversification of bees: Paleohabropoda oudardi from the French Paleocene (Hymenoptera, Apidae, Anthophorini)

Phylogenetic relationships among and within the major groups of bees (Apoidea Apiformes) were recently reconsidered using extensive molecular and morphological datasets. The next step in the study of

An Ancient Origin for the Enigmatic Flat-Headed Frogs (Bombinatoridae: Barbourula) from the Islands of Southeast Asia

The divergences within Barbourula and between it and Bombina are surprisingly old and represent the oldest estimates for a cladogenetic event resulting in living taxa endemic to Southeast Asian islands.

A biogeographic view on Southeast Asia's history

S Sulawesi and its peculiar fauna is tested to test if a vicariant origin appears plausible for certain groups and when the remarkable fish and snail radiations found in the Malili Lakes system started to diversify, and a “tectonic dispersal” vicariance hypothesis from the Australian margin could not be refuted for three taxa.



Oligocene sivaladapid primate from the Bugti Hills (Balochistan, Pakistan) bridges the gap between Eocene and Miocene adapiform communities in Southern Asia.

The presence in Pakistan of an unique and well-diversified Oligocene primate fauna clearly demonstrates that South Asia maintained favourable environmental conditions during the middle Caenozoic global climatic deterioration that coincides with drastic changes in faunal structure on the whole Holarctic Province, including the extinction of adapiform primates.

Discovery of Fallomus ladakhensis Nanda & Sahni, 1998 (Mammalia, Rodentia, Diatomyidae) in the lignites of Nong Ya Plong (Phetchaburi Province, Thailand) : systematic, biochronological and paleoenvironmental implications

The paleontological surveys in the lignites of the Tertiary basin of Nong Ya Plong in Central Thailand have led to the discovery of a new fossiliferous locality. This locality, located in the Cha

The colugo (Cynocephalus variegatus, Dermoptera): the primates' gliding sister?

The presence/absence pattern of transposable elements that provide a nearly homoplasy-free and copious source of molecular evolutionary markers, with well-defined character polarity, are determined, clearly supporting the monophyly of primates by retropositional evidence.

Dental Function in the Plagiomenidae: Origin and Relationships of the Mammalian Order Dermoptera

A study of molar wear patterns of plagiomenids is presented that further supports their affinity with the extant dermopteran Cynocephalus, and shares certain functional features of the molars with members of the Paleocene family Mixodectidae, indicating that these two families are closely allied.

The role of Asia in the origin and diversification of hystricognathous rodents

A cladistic assessment of the dental evidence for the Palaeogene hystricognathous rodent cladogenesis indicates that ‘baluchimyines’ and tsaganomyids are representatives of an initial phase of diversification of hystricsened rodents in Asia, which clearly points to an Asian origin for HyStricognathi.

Late eocene sivaladapid primate from Guangxi Zhuang Autonomous Region, People's Republic of China.

Phylogenetic analysis of dental characters suggests that Guangxilemur tongi is closely related to the Miocene sivaladapine clade, which includes Hoanghonius, Rencunius, and Wailekia in addition to Guangxilesmur.

Craniodental morphology and relationships of the supposed Eocene dermopteran Plagiomene (Mammalia)

This report analyzes the basicranial morphology of a skull referable to the nominotypical genus Plagiomene from the early Eocene Willwood Formation of the Bighorn Basin, Wyoming, which exhibits one of the most highly derivedbasicranial regions found in Eutheria.

New basicrania of Paleocene-Eocene Ignacius: re-evaluation of the Plesiadapiform-Dermopteran link.

It is shown that newly discovered crania of Ignacius graybullianus, preserving previously undocumented portions of the ear, are more similar to primates than to dermopterans, indicating that Paromomyidae is likely to be more closely related to other Paleogene Plesiadapiformes and Eocene Primates than to extant Dermoptera.

A Middle Miocene hominoid from Thailand and orangutan origins

The origin of orangutans has long been debated. Sivapithecus is considered to be the closest ancestor of orangutans because of its facial–palatal similarities, but its dental characteristics and

Eocene plesiadapiform shows affinities with flying lemurs not primates

The first well-preserved skull of Ignacius graybullianus, an early Eocene paromomyid plesiadapiform, clarifies and corrects previous cranial reconstruction based on more fragmentary material, and indicates PlesiadAPiformes are not Primates, and the recently coined taxon "Euprimates" should be discarded.
