AbstractThe Middle Eocene locality of Eocliff, Namibia, has yielded a rich vertebrate fauna, including mainly mammals, but also a few bird remains. A coracoid and a scapula are ascribed to a new genus and a new species of galliform in the extinct family Paraortygidae. This family was so far known only from the Late Eocene and Early Oligocene of the northern hemisphere. A distal part of tarsometatarsus is ascribed to a new genus and a new species of psittaciform. This tarsometatarsus shows a… Expand
A small stem-galliform bird (Aves: Paraortygidae) from the Eocene of Uzbekistan
Abstract Landfowl (order Galliformes) are among the most characteristic birds of the modern avian faunas, but their early evolutionary history is insufficiently known. The diversity of previouslyExpand
New Bird Taxa (Aves: Galliformes, Gruiformes) from the Early Eocene of Mongolia
Abstract New bird taxa are described from the early Eocene Bumban Member of the Tsagaan-Khushuu locality in southern Mongolia. Bumbanortyx transitoria gen. et sp. nov. is a small galliform bird thatExpand
Evidence for Wide Dispersal in a Stem Galliform Clade from a New Small-Sized Middle Eocene Pangalliform (Aves: Paraortygidae) from the Uinta Basin of Utah (USA)
A new bird coracoid from the Uinta Formation in the Uinta Basin in Utah (USA) records the presence of the only known pangalliform from the middle Eocene of North America, occurring in a >15 millionExpand
Tufamyidae, a new family of hystricognath rodents from the Palaeogene and Neogene of the Sperrgebiet, Namibia
The Palaeogene tufa deposits at Eocliff are a ric h source of micromammals, probably the richest such site in Africa, having yielded thousan ds of specimens, including complete skulls, mandibl es andExpand
New remains of the very small cuckoo,Chambicuculus pusillus (Aves, Cuculiformes, Cuculidae) from the late Early or early Middle Eocene of Djebel Chambi, Tunisia
A very tiny cuckoo, Chambicuculus pusillus, was recently described after a few fragments of tarsometatarsi from the late Early/early Middle Eocene of Djebel Chambi, Tunisia. New remains, notably aExpand
Additional material of Namahyrax corvus from the Ypresian/Lutetian of Black Crow, Namibia
Three teeth of a small hyracoid were found during the 2017 campaign of acid digestion of blocks of limestone from Black Crow, Namibia. The s pecimens, a left D1/, half an upper premolar and a rightExpand
First discovery of avian egg and bone remains (Presbyornithidae) from the Gour Lazib (Eocene, Algeria)
Abstract Numerous avian eggshells and one well-preserved small ovoid-shaped egg (32 × 28 mm) were collected from three localities in the Gour Lazib area (HGL10, HGL51 and HGL62), western Algeria fromExpand
The evolution of a tropical biodiversity hotspot
It is observed that higher and more constant speciation rates occur in harsh environments relative to the tropics, and the results reveal a model in which species are forming faster in environmental extremes but have accumulated in moderate environments to form tropical biodiversity hotspots.

The first Palaeogene galliform from Africa
An almost complete tarsometatarsus from the middle Eocene locality of Silica South, Sperrgebiet, Namibia, is attributed to the order Galliformes, the earliest record of the order in Africa, and it is clear that it represents a new genus and species of galliform bird, which is named Namaortyx sperragbietensis.

New specimens of the early Eocene stem group galliform Paraortygoides (Gallinuloididae), with comments on the evolution of a crop in the stem lineage of Galliformes

Two new specimens of the fossil stem group galliform Paraortygoides messelensis Mayr 2000 (Gallinuloididae) are described from the Middle Eocene of Messel in Germany, including a complete skeleton inExpand
A new basal galliform bird from the Middle Eocene of Messel (Hessen, Germany)
The cup-like cotyla scapularis ofParaortygoides messelensis shows that the Gallinuloididae branched off very early in the evolution of the Galliformes. Expand
Stem Parrots (Aves, Halcyornithidae) from the Green River Formation and a Combined Phylogeny of Pan-Psittaciformes
Fossil evidence is consistent with a more recent origin of crown clade Psittaciformes than predicted from divergence dating analyses, and supports environmental shifts and dispersal as key drivers in parrot biogeography. Expand
Galliformes, Upupiformes, Trogoniformes, and other avian remains (?Phaethontiformes and ?Threskiornithidae) from the Rupelian stratotype in Belgium, with comments on the identity of “Anas” benedeni Sharpe, 1899
We describe new avian fossils from the Boom Formation of Belgium, which almost double the number of bird taxa known from this part of the Rupelian stratotype. Three galliform species can, at leastExpand
Quercypsitta-Like Birds from the Early Eocene of India (Aves, ?Psittaciformes)
It is concluded that, at least concerning the arboreal taxa, the early Eocene avifauna of India shows some concordances with the much better known one from the late Eocene of Europe, and is assigned to a new family, Vastanavidae. Expand
A small galliform and a small cuculiform from the Eocene of Tunisia
A distal tarsometatarsus and a fragment of carpometacarpus of a small galliform, the size of a recent quail, have been found in the late Early or early Middle Eocene of Chambi, in Tunisia, and is described as a new genus and species. Expand
On the osteology and phylogenetic affinities of the Pseudasturidae–Lower Eocene stem-group representatives of parrots (Aves, Psittaciformes)
Derived osteological characters which are visible in newly recognized specimens from the Lower Eocene London Clay of England most convincingly support classification of the Pseudasturidae into the Psittaciformes (parrots). Expand
The Fossil Galliform Bird Paraortygoides from the Lower Eocene of the United Kingdom
The results of a preliminary phylogenetic analysis suggest that Paraortygoides is basal within Galliformes (as already proposed by Mayr [2000]); monophyly of the order is supported with Megapodiidae as the basal sister taxon with respect to the Cracidae and Phasianidae. Expand
A new family of Eocene zygodactyl birds
The Pseudasturidae, a new family of small Lower to Middle Eocene zygodactyl birds is described in the Middle Eolithic of Grube Messel, near Darmstadt (Hessen, Germany), and the presence of large processus supraorbitales, which closely resemble the corresponding structures found in falconiform birds is characteristic.
