Bird tracks from the Green River Formation (Eocene) of Utah: ichnotaxonomy, diversity, community structure and convergence
- Environmental Science, GeographyHistorical Biology
ABSTRACT Abundant well-preserved bird tracks from lacustrine Green River Formation (Eocene) deposits in Utah, are diverse and paleoecologically significant, but remain poorly known. Three of the four…
First diagnosable non-sphenisciform bird from the early Paleocene of New Zealand
A new avian taxon from the early Paleocene Waipara Greensand in Canterbury, New Zealand, is described. The holotype of Australornis lovei, gen. et sp. nov. includes wing and pectoral girdle bones,…

Skeleton of a New Owl from the Early Eocene of North America (Aves, Strigiformes) with an Accipitrid-Like Foot Morphology
- Biology, Environmental ScienceJournal of Vertebrate Paleontology
It is hypothesize that a large-sized owl from Wasatchian strata of the Willwood Formation used its feet to dispatch prey items in a hawk-like manner, whereas extant owls kill prey with their beak.
An early Oligocene stem Galbulae (jacamars and puffbirds) from southern France, and the position of the Paleogene family Sylphornithidae
- Biology, GeographyThe Auk
A new fossil bird, named Jacamatia luberonensis, found in France and aged 30 myr, is the first pre-Pleistocene fossil for the whole suborder Galbulae (jacamars and puffbirds), and tentatively within the family Sylphornithidae.

A complete update of the fossil record of birds from Antarctica is provided, commenting on the importance of some of these remains for the evolution of the major clades.
A swan-sized anseriform bird from the late Paleocene of Mongolia
- Environmental Science, GeographyJournal of Vertebrate Paleontology
The new taxon Naranbulagornis khun represents the earliest global evidence of a spatial coexistence between presbyornithids and other basal waterfowl during the early Paleogene and indicates a greater morphological diversity of early Cenozoic anseriforms than previously thought.
Articulated avian remains from the early Oligocene of Poland adds to our understanding of Passerine evolution
- Environmental Science
In total, less than 50 specimens of the Passeriformes are known from the Paleogene, which contrasts with the fact that now it is the largest and most diverse order of birds. The so far described…
