Gerald Mayr, Auteur ; James L. Goedert, Auteur ; Renate Rabenstein, AuteurWe describe the fossil cranium of a pheasant-sized galliform land bird from latest Eocene or earliest Oligocene marine rocks of the Jansen Creek Member, Makah Formation (Washington State, USA), which is the only three-dimensionally preserved cra[...]
Article
Cheng-Hsiu Tsai, Auteur ; Gerald Mayr, AuteurTaiwan accommodates more than 600 avian species, including about 30 endemic ones. As yet, however, no fossil birds have been scientifically documented from Taiwan, so that the evolutionary origins of this diversified avifauna remain elusive. Her[...]
Article
Gerald Mayr, Auteur ; Vanesa L. De Pietri, Auteur ; Richard Paul Scofield, Auteur ; Thierry Smith, AuteurWe describe the earliest temporally well-constrained fossil that can be assigned to the Ardeidae (herons), from the lowermost Oligocene (32.0-33.0 million years ago) of Belgium. The specimen, a partial tarsometatarsus, belongs to a small species[...]
Article
Gerald Mayr, AuteurPasseriform birds exhibit previously unreported differences in the course of the arteria ophthalmica externa in the middle ear, which can easily be traced through examination of the involved osseous structures. In the Suboscines and most of the [...]
Article
Gerald Mayr, AuteurThe evolution of the avian flight musculature is poorly understood and most studies focused on Archaeopteryx. However, important evolutionary changes occurred within Aves, and here the morphology of the pectoral girdle of Mesozoic birds is inter[...]
Article
Gerald Mayr, AuteurNew specimens of Scaniacypselus szarskii, a stem group representative of the Apodidae (true swifts) from the middle Eocene Messel oilshale in Germany, are described. These fossils show that Scaniacypselus differs from crown group Apodidae in a n[...]
Article
Gerald Mayr, AuteurA partial skeleton of the early Eocene tropicbird Prophaethon shrubsolei (Prophaethontidae) from the London Clay of Walton-on-the-Naze (UK) is described. Most of the bones preserved in this fossil have not been described previously for Prophaeth[...]

Article
Gerald Mayr, Auteur ; Charles W. Knopf, AuteurA new species of the charadriiform taxon Turnipax Mayr, 2000 is described from the Lower Oligocene fossil site Frauenweiler in southern Germany. The postcranial skeleton assigned to Turnipax oechslerorum sp. nov. is very well preserved and allow[...]
Article
Gerald Mayr, AuteurA partial skeleton of a medium-sized fossil rail is described from the early Oligocene of Hofheim-Wallau in Germany and tentatively assigned to Belgirallus oligocaenus Mayr & Smith 2001. It is the earliest substantial fossil record of Rallidae a[...]
Article
Gerald Mayr, AuteurMolecular analyses support a sister group relationship between the African Cuckoo Finch (Anomalospiza imberbis) and Viduidae (whydahs and indigobirds). This result was interpreted as evidence for a single origin of brood parasitism in Old World [...]
Article
Gerald Mayr, AuteurA tarsometatarsus of a diminutive representative of the Phalacrocoracoidea, the clade including the Phalacrocoracidae (cormorants) and Anhingidae (anhingas), is described from the early Miocene of Germany. The fossil is assigned to a new species[...]
Article
N. Adam Smith, Auteur ; Gerald Mayr, AuteurNewly discovered fossil remains of an auk (Aves, Charadriiformes) extend the temporal range of Pan-Alcidae in the northeastern Atlantic Ocean basin and the geographic range of the clade during the Miocene. The new specimen consists of a partial [...]

Article
Gerald Mayr, AuteurA new fossil stem group representative of Coliiformes (mousebirds) with a remarkable skull morphology is described from the late Oligocene of Germany. Oligocolius psittacocephalon sp. nov. for the first time preserves the skull of a post-Eocene [...]
Article
Cristeta Brause, Auteur ; Hagen Gasse, Auteur ; Gerald Mayr, AuteurIn swifts and hummingbirds (Apodiformes), the splenius capitis muscle displays a characteristic modification, the 'cruciform origin'. The muscle pairs arise from the second vertebra by several slips which criss-cross and interdigitate with each [...]
Article
Gerald Mayr, AuteurNew specimens of the early Oligocene (32 million years ago) stem group hummingbird Eurotrochilus inexpectatus Mayr, 2004, are described from the type locality Frauenweiler in Southern Germany. One of these is the second slab of the holotype, who[...]
Article
Gerald Mayr, AuteurRecent phylogenetic analyses provide strong evidence for some previously undetected clades of morphologically very divergent avian groups. Also, within the past decades, palaeornithology has experienced a renaissance and the Paleogene fossil rec[...]
