Ratitae is represented in South America exclusively by Rheidae. Recently, the oldest purported fossil rheid, Diogenornis fragilis, was attributed by several authors to various other ratite clades. A new revision of museum fossil specimens from Argentina has resulted in the discovery of several ratite… 

The Evolution and Fossil Record of Palaeognathous Birds (Neornithes: Palaeognathae)

The extant diversity of the avian clade Palaeognathae is composed of the iconic flightless ratites (ostriches, rheas, kiwi, emus, and cassowaries), and the volant tinamous of Central and South

New details of the hindlimb morphology of the species are reported based on unpublished and previously described fossils from the Geiseltal and show close affinities between the Palaeotididae and Geranoididae.

Extinct crane-like birds (Eogruidae and Ergilornithidae) from the Cenozoic of Central Asia are indeed ostrich precursors

New fossils from the late Eocene of Mongolia are described, which corroborate earlier assumptions that the Ergilornithidae as well as the closely related Eogruidae are struthioniform birds and suggest that true ostriches originated in Asia.

Dietary isotopes of Madagascar's extinct megafauna reveal Holocene browsing and grazing guilds

Megafauna play a disproportionate role in developing and maintaining their biomes, by regulating plant dispersal, community structure and nutrient cycling. Understanding the ecological roles of

The Miocene: The Future of the Past

The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and

Aerobic performance in tinamous is limited by their small heart. A novel hypothesis in the evolution of avian flight

This work proposes the “heart to fly” hypothesis that states that sustained flapping flight in modern birds required an enlargement of the heart for the aerobic performance of the flight muscles and test it experimentally by studying tinamous, the living birds with the smallest hearts.

A new Transantarctic relationship: morphological evidence for a Rheidae–Dromaiidae–Casuariidae clade (Aves, Palaeognathae, Ratitae)

A novel pattern of diversification of ratites is presented, which indicates that Australia and South America remained in contact across Antarctica until the earliest Tertiary, and repeated patterns of area relationships agree with current knowledge on Gondwana break-up.

Phylogenetic relationships of the Australian Oligo-Miocene ratite Emuarius gidju Casuariidae.

A phylogenetic analysis of morphological data robustly shows that E. gidju is the sister taxon of Dromaius and together these taxa form a clade that is sister to Casuarius, indicating that the evolution towards enhanced cursorality that characterises Dromaeus took place after the divergence of the emu-cassowary lineages and was likely not the driving mechanism of this divergence.

A new global palaeobiogeographical model for the late Mesozoic and early Tertiary.

A new biogeographical model for late Mesozoic terrestrial ecosystems is proposed in which Europe and "Gondwanan" territories possessed a common Eurogondwanans fauna during the earliest Cretaceous, and tree reconciliation analyses (TRAs) were performed based onBiogeographical signals provided by a supertree of late Meszoic archosaurs.

Earliest tinamous (Aves: Palaeognathae) from the Miocene of Argentina and their phylogenetic position

Placement of the Santa Cruz fossil tinamous between the open-area (Nothurinae) and the forest-dwelling (‘‘Tinaminae’’) tinamous is consistent with the paleoenvironmental conditions inferred from the associated fossil fauna.


Fossil ratite eggshell fragments recovered from the Late Miocene Baynunah Formation, United Arab Emirates, are described as Diamantornis laini and as an aepyornithid-type eggshell fragment. D. laini

Higher-order phylogeny of modern birds (Theropoda, Aves: Neornithes) based on comparative anatomy. II. Analysis and discussion

A phylogenetic (cladistic) analysis of 150 taxa of Neornithes, including exemplars from all non-passeriform families, and subordinal representatives of Passeriformes, confirmed the topology among outgroup Theropoda and achieved robust resolution at virtually all levels of the NeornIthes.

New Ratite Eggshells from the Miocene of Namibia

Namibian Neogene deposits have yielded a remarkably comprehensive register of fossil ratite eggshells spanning the entire Miocene and Plio-Pleistocene. Previous studies recognised three genera of

South American and Antarctic Continental Cenozoic Birds: Paleobiogeographic Affinities and Disparities

Several advances have been made on the understanding of the biotic and environmental history of South America and Antarctica including the discovery of additional fossil sites coupled with progress

Review of the putative Phorusrhacidae from the Cretaceous and Paleogene of Antarctica: new records of ratites and pelagornithid birds

There is no empirical evidence for the presence of terror birds in Antarctica, and the indeterminate Pelagornithidae specimen represents the largest pseudo−toothed bird known so far.
