ABSTRACT We describe a partial skeleton of a large-sized owl from Wasatchian strata of the Willwood Formation (Wyoming, U.S.A.). The holotype of Primoptynx poliotauros, gen. et sp. nov., includes all major postcranial bones and is one of the most substantial Paleogene records of the Strigiformes. The fossil shows that owls exhibited a considerable morphological diversity in the early Eocene of North America and occupied disparate ecological niches. As in the protostrigid taxon Minerva from the… Expand
A partial skeleton of a new species of Tynskya Mayr, 2000 (Aves, Messelasturidae) from the London Clay highlights the osteological distinctness of a poorly known early Eocene “owl/parrot mosaic”
Tynskya eocaena is an early Eocene bird with a raptor-like skull and semi-zygodactyl feet, whose description is based on a skeleton from the North American Green River Formation. In the presentExpand
The coracoscapular joint of neornithine birds—extensive homoplasy in a widely neglected articular surface of the avian pectoral girdle and its possible functional correlates
TLDR
In taxa with a large crop, a flat facies articularis scapularis is likely to be associated with a reorganization of the pectoral musculature, whereas in procellariiform birds, the transition from a cotyla to a faciesArticularis appears to have been correlated with the capacity for sustained soaring without wing flapping.

TLDR
It is hypothesized that pleurocoels primarily serve to increase the structural resistance of the vertebral body and were reduced multiple times in neornithine birds. Expand

The world’s smallest owl, the earliest unambiguous charadriiform bird, and other avian remains from the early Eocene Nanjemoy Formation of Virginia (USA)
TLDR
All bird fossils from the Nanjemoy Formation are three-dimensionally preserved and, therefore, allow a detailed assessment of osteological features, which complements studies of compression fossils from lagerstätten-type fossil sites. Expand

TLDR
A new taxon of barn owl is described from the Middle Miocene localities at Steinberg and Goldberg in the Nordlinger Ries (Southern Germany) and shows some characters intermediate with Strigidae. Expand
THE BIRDS FROM THE PALEOCENE FISSURE FILLING OF WALBECK (GERMANY)
TLDR
All of the sufficiently well-preserved avian taxa belong to terrestrial forms, and by its species poorness the Walbeck avifauna sharply contrasts with the very diverse avifaunas known from the earliest Eocene of Europe. Expand
