The living Laotian rodent Laonastes aenigmamus, first described in early 2005, has been interpreted as the sole member of the new family Laonastidae on the basis of its distinctive morphology and apparent phylogenetic isolation from other living rodents. Here we show 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. Laonastes is a particularly striking… Expand
First diatomyid rodent from the Early Miocene of Arabia
The Asian family Diatomyidae is known from the Early Oligocene to the present. Among living rodents, this group comprises only the recently discovered Laonastes aenigmamus from Laos. FossilExpand
Discovery of a Giant Chameleon-Like Lizard (Anolis) on Hispaniola and Its Significance to Understanding Replicated Adaptive Radiations
A new chameleon-like Anolis species from Hispaniola that is ecomorphologically similar to congeners found only on Cuba is reported that supports the hypothesis that the assembly of island faunas can be substantially deterministic and highlights the continued potential for basic discovery to reveal new insights in well-studied groups. Expand
The epitensoric chorda tympani of Laonastes aenigmamus (Rodentia, Diatomyidae) and its phylogenetic implications
Newly made histological serial sections of a fetal stage reveal that Laonastes aenigmamus (Diatomyidae), a rodent species first described in 2005, is epitensoric as well, substantiating a sister group relationship between Diatomyaceae and Ctenodactylidae. Expand
A new and primitive species of Protophiomys (Rodentia, Hystricognathi) from the late middle Eocene of Djebel el Kébar, Central Tunisia
Based on fossil discoveries and phylogenetic studies, an Eocene Asian origin for hystricognathous rodents and anthropoid primates has gained strong support in recent years. The two groups thenExpand
Emerging perspectives on some Paleogene sciurognath rodents in Laurasia: the fossil record and its interpretation
One of the striking evolutionary successes among vertebrates centers on the mammalian order Rodentia, which exhibits both a respectably long geologic history, extending back to the late Paleocene (c.Expand
Zegdoumyidae (Rodentia, Mammalia), stem anomaluroid rodents from the Early to Middle Eocene of Algeria (Gour Lazib, Western Sahara): new dental evidence
The Palaeogene fossil record of rodents in Africa is very poor compared to that of North America or Eurasia. Despite this, Africa has long appeared to be a centre of adaptive radiation for twoExpand
Multiple molecular evidences for a living mammalian fossil
A large-scale molecular phylogeny of rodents found that Laonastes and Diatomyidae are the sister clade of extant Ctenodactylidae and do not belong to the Hystricognathi, and alternative hypotheses were significantly rejected based on Shimodaira–Hasegawa tests. Expand
A Remarkable Case of Micro-Endemism in Laonastes aenigmamus (Diatomyidae, Rodentia) Revealed by Nuclear and Mitochondrial DNA Sequence Data
The results suggest that L. aenigmamus may represent a complex of species and/or sub-species and an inland insular model for Laonastes population structure, and increases the necessity for a strict protection of this rare animal and its habitat. Expand
The Diatomyidae (Mammalia, Rodentia) and Bilophodonty in Middle Eocene Asian Rodents
The incomplete record of this new taxon as well as its morphology cannot answer the question of whether this taxon is allied to such later appearing strongly bilophodont rodents as diatomyids and pedetids, or is an early experiment of this striking morphological development that left no successors. Expand
On a new diatomyid (Rodentia, Mammalia) from the Paleogene of south-east Serbia, the first record of the family in Europe
A new diatomyid genus and species, Inopinatia balkanica, from the early Oligocene of south-east Serbia is described, and the affinities between the Diatomyidae and Ctenodactylidae are discussed.Expand


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.

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 ChaExpand
Catagonus, an "Extinct" Peccary, Alive in Paraguay
A third species of peccary, discovered in the Chaco of Paraguay, is added to the living members of family Tayassuidae. It is assigned to the genus Catagonus Ameghino, heretofore considered confinedExpand
Morphological and molecular investigations of a new family, genus and species of rodent (Mammalia: Rodentia: Hystricognatha) from Lao PDR
Abstract During biodiversity surveys in Khammouan Province, Lao Peoples Democratic Republic, specimens of an unknown species of hystricognathous rodent were discovered in local markets being sold forExpand
Les mammifères du gisement miocène inférieur de Li Mae Long, Thaïlande : systématique, biostratigraphie et paléoenvironnement
The fauna of Li Mae Long (Lamphun district, Thailand) includes thirtythree Placental Mammals, with five Insectivora (Thaiagymnura equilateralis n.sp.), nine Bats, and the genus Diatomys does not show any adaptation for jumping. Expand
High‐level phylogeny of early Tertiary rodents: dental evidence
A cladistic assessment of the dental evidence for early Tertiary rodent cladogenesis provides evidence of a fundamental dichotomy in early rodent history, including the pentalophodonty of molars, zygomasseteric complex and incisor enamel microstructure. Expand

What are Lazarus taxa
Analytical techniques assessing the completeness of the fossil record are critical to understand the meaning of Lazarus taxa, and the Lazarus effect should be defined broadly to include range gaps from any given time interval. Expand
Biodiversity hotspots for conservation priorities
A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed. Expand
