The extinct dromornithids, gastornithids and phorusrhacids are among the most spectacular birds to have ever lived, with some giants exceeding 500 kg. The affinities and evolution of these and other related extinct birds remain contentious, with previous phylogenetic analyses being affected by widespread convergence and limited taxon sampling. We address these problems using both parsimony and tip-dated Bayesian approaches on an expansive taxon set that includes all key extinct flightless and…

Endocranial Anatomy of the Giant Extinct Australian Mihirung Birds (Aves, Dromornithidae)

Functional interpretations suggest that dromornithids were specialised herbivores that likely possessed well-developed stereoscopic depth perception, were diurnal and targeted a soft browse trophic niche.

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

Late Cretaceous neornithine from Europe illuminates the origins of crown birds

A newly discovered fossil from the Cretaceous of Belgium is the oldest modern bird ever found, showing a unique combination of features and suggesting attributes shared by avian survivors of the end-Cretaceous mass extinction.

Reappraisal on the Phylogenetic Relationships of the Enigmatic Flightless Bird (Brontornis burmeisteri) Moreno and Mercerat, 1891

It is concluded that Brontornis does belong to Galloanserae, and that it represents a member of a largely unknown radiation of giant graviportal birds from South America.

First Record of a Giant Bird (Ornithuromorpha) from the Uppermost Maastrichtian of the Southern Pyrenees, Northeast Spain

This finding demonstrates that large-sized birds were part of the ecological communities of the Ibero-Armorican island from the late Campanian to the Late Maastrichtian, being present during the last hundreds of thousands of years prior to the K/Pg extinction event.

Phylogenetic relationships of the Early Miocene diving and flightless duck Cayaoa bruneti (Aves, Anatidae) from Patagonia: homology or convergence?

A new phylogenetic analysis using only morphological characters places Cayaoa bruneti as part of a single radiation of diving ducks within Anatinae, as sister group to the Erismaturinae.

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.

Body size evolution in palaeognath birds is consistent with Neogene cooling-linked gigantism




The Extinct Flightless Mihirungs (Aves, Dromornithidae): Cranial Anatomy, a New Species, and Assessment of Oligo-Miocene Lineage Diversity

A well-preserved cranium from the middle Miocene Bullock Creek Local Fauna is described and morphological similarity of this cranial material suggests that the emusized B. tedfordi is a smaller precursor to and differs little from species of Ilbandornis.

Osteology Supports a Stem-Galliform Affinity for the Giant Extinct Flightless Bird Sylviornis neocaledoniae (Sylviornithidae, Galloanseres)

Sylviornis neocaledoniae is found to be a stem galliform, distant from megapodiids, and the sister taxon to the extinct flightless Megavitiornis altirostris from Fiji, which is transferred to the family Sylviornithidae.


This analysis provided a case study in the application of phylogenetic nomenclature at the species level and evaluated the relationships among Mesozoic ornithurines including Ichthyornis dispar and the newly identified taxa.

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.

Systematic relationships of the palaeogene family Presbyornithidae (Aves: Anseriformes)

The often suggested close relationship of anseriform and galliform birds is not confirmed by osteology, and the Anseriformes and the Phoenicopteridae form a monophyletic clade that is the sister to the remaining ciconiiform birds.

The unexpected survival of an ancient lineage of anseriform birds into the Neogene of Australia: the youngest record of Presbyornithidae

The morphological similarity between species of Wilaru and the Eocene South American presbyornithid Telmabates antiquus supports the hypothesis of a Gondwanan radiation during the evolutionary history of the PresbyORNithidae and underscores the temporal continuance of Australia’s vertebrates.

Phylogenomics and Morphology of Extinct Paleognaths Reveal the Origin and Evolution of the Ratites

Ancient DNA reveals elephant birds and kiwi are sister taxa and clarifies ratite bird evolution

It is suggested that convergence toward gigantism and flightlessness was facilitated by early Tertiary expansion into the diurnal herbivory niche after the extinction of the dinosaurs.

Morphology of the quadrate in the Eocene anseriform Presbyornis and extant galloanserine birds

The quadrate's morphology is inconsistent with the currently accepted anseriform phylogeny that nests Presbyornis within the crown‐group as a close relative of the Anatidae and shares ancestral galloanserine characters with the Megapodiidae, the earliest branch of extant galliforms.

Phylogenetic interrelationships of living and extinct Tinamidae, volant palaeognathous birds from the New World

Temporal calibration of the resultant phylogeny indicates that such a basal divergence had already taken place in the early Miocene, some 17 million years ago, and the placement of the fossil species within the open-area and the forest-dwelling tinamous is consistent with the palaeoenvironmental conditions inferred from the associated fauna.
