Asian gliriform origin for arctostylopid mammals

  title={Asian gliriform origin for arctostylopid mammals},
  author={Pieter Missiaen and Thierry Smith and Dianbin Guo and Jonathan I. Bloch and Philip D. Gingerich},
Arctostylopids are common in Late Palaeocene and Early Eocene mammal faunas of Asia, but they are rare in North America. From the time of their first discovery, arctostylopids were grouped with the strictly endemic South American Notoungulata based on their strikingly similar dental morphology. This relationship was challenged based on dental morphology of more recently discovered arctostylopids and on supposed tarsal morphology (based on unassociated material) of the Asian arctostylopid… Expand

Figures and Topics from this paper

A large new collection of Palaeostylops from the Paleocene of the Flaming Cliffs area (Ulan-Nur Basin, Gobi Desert, Mongolia), and an evaluation of the phylogenetic affinities of Arctostylopidae (Mammalia, Gliriformes)
The study of the morphology and size of the new Palaeostylops dental material confirms the validity of two species, P. iturus and P.macrodon, and illustrates their morphological and biometrical variability and diagnostic differences, as well as the first known arctostylopid distal tibia. Expand
Chulpasia and Thylacotinga, late Paleocene-earliest Eocene trans-Antarctic Gondwanan bunodont marsupials: New data from Australia
A new marsupial from the early Eocene Tingamarra Local Fauna of southeastern Queensland, Australia, is named and referred to Chulpasia Crochet and Sige, 1993, a genus otherwise known from earlyExpand
Tarsal diversity in the earliest Eocene mammal fauna of Dormaal, Belgium
This study chose the Belgian locality of Dormaal (Tienen Formation, Belgium) that has yielded the earliest Eocene mammals of Europe, representing about 14,000 dental specimens, to associate tarsal bones with dental specimens for a systematic identification. Expand
The Gashatan (Late Paleocene) Mammal Fauna from Subeng, Inner Mongolia, China
It is proposed that the Gashatan faunas are less endemic than previously thought, and result from a significant exchange with North American faunaas from the late Paleocene. Expand
Paleocene Malvaceae from northern South America and their biogeographical implications.
The abundance of eumalvoid leaves and of bombacoid pollen in the midlate Paleocene of Colombia suggests that the Malvatheca group (Malvoideae + Bombacoideae) was already a common element in neotropical forests and does not support an Australasian origin for Eumalvoides. Expand
Taxonomic revision of Eoalligator (Crocodylia, Brevirostres) and the paleogeographic origins of the Chinese alligatoroids
The taxonomic revisions imply that four alligatoroids are currently known from China, and these species must have dispersed from North America to Asia in more than one event. Expand
Convergent and Parallel Evolution in Early Glires (Mammalia)
Overall, this chapter focuses on convergence and parallelism observed in the dental and pedal characters of the early Glires, with emphasis on the duplicidentates. Expand
Early Eocene lagomorph (Mammalia) from Western India and the early diversification of Lagomorpha
The Indian fossils suggest that diversification within crown Lagomorpha and possibly divergence of the family Leporidae were already underway in the Early Eocene. Expand
Afrotherian affinities for endemic South American “ungulates”
New data based on many fossil specimens preserving deciduous dentition and a morphometric assessment of those specimens, together with a revision of available postcranial anatomy in relevant fossils are used to examine the distribution of the three characters in placental phylogeny. Expand
Woodland in a f luvio-lacustrine environment on the dry Mongolian Plateau during the late Paleocene : Evidence from the mammal bearing Subeng section ( Inner Mongolia , P . R . China )
In the understanding of the global faunal turnover during the Paleocene–Eocene transition, an important role has been attributed to the Asian continent, although the Asian fossil record for thisExpand

A new Paleocene nyctitheriid insectivore from Inner Mongolia [China] and the origin of Asian nyctitheriids
Nyctitheriids are primitive insectivores that were relatively abundant and diverse in North America and Europe during the middle Paleocene through to the middle Oligocene. The nyctitheriids from AsiaExpand
Eutherian tarsals from the late Paleocene of Brazil. American Museum novitates ; no. 2761
Disassociated eutherian proximal tarsals (astragalus, calcaneum) from Riochican (late Paleocene) fissure fills near Sao Jose de Itaborai, Rio de Janeiro, Brazil, are described and, where feasible,Expand
This study consists of a taxonomic revision of the genus, a detailed description of the osteological morphology, extensive analyses on morphological characters, analyses on phylogeny, discussions on divergence time of the Glires, and analyses on functional morphology of mastication and locomotion.

Oldest Plesiadapiform (Mammalia, Proprimates) from Asia and its palaeobiogeographical implications for faunal interchange with North America
Abstract Carpolestid plesiadapiforms are well known in several lineages from the North American Palaeocene, but they are absent from Europe and known, until now, by only two taxa from the EarlyExpand
Dental and tarsal morphology of the European Paleocene/Eocene “condylarth” mammal Microhyus
Functional analysis of the dental and postcranial remains of the alleged louisinine hyopsodontid “condylarth” Microhyus from the European Paleocene/Eocene transition are described, and prompt a reevaluation of the genus. Expand
