Abstract A new skeleton of the Early Eocene stem group mousebird Masillacolius brevidactylus is described, which for the first time provides information on the skull morphology of this unusual coliiform species. Notably, the mandible exhibits long, blade-like retroarticular processes, which were previously only known from two distantly related taxa of stem group Coliiformes. An assessment of the evolutionary significance of these structures depends on the phylogenetic interrelationships of stem… Expand
New data on the anatomy and palaeobiology of sandcoleid mousebirds (Aves, Coliiformes) from the early Eocene of Messel

TLDR
It is hypothesised that differences in the tail morphology of sandcoleids and coliids may have been due to changes in the habitual perching posture, which occurred early in the evolutionary history of the Coliidae. Expand
Early Eocene (Ypresian) birds from the Okanagan Highlands, British Columbia (Canada) and Washington State (USA)
We survey the known avian fossils from Ypresian (early Eocene) fossil sites of the North American Okanagan Highlands, mainly in British Columbia (Canada). All specimens represent taxa that wereExpand
The early Eocene birds of the Messel fossil site: a 48 million‐year‐old bird community adds a temporal perspective to the evolution of tropical avifaunas

TLDR
The crown groups of most avian taxa that already existed in early Eocene forests are species‐poor, which does not support the hypothesis that the antiquity of tropical ecosystems is key to the diversity of tropical avifaunas, and suggests that high diversification rates may be of greater significance.

A new eocene Chascacocolius-like mousebird (Aves: Coliiformes) with a remarkable gaping adaptation
TLDR
A skull of a new species of mousebird (Aves: Coliiformes) is described from the Middle Eocene of Messel in Germany, and the cranium and upper beak of Chascacocolius are seen for the first time in the new specimen; the latter shows a striking resemblance to some modern New World Blackbirds (Passeriformes: Icteridae).

Affinities of Palaeospiza bella and the Phylogeny and Biogeography of Mousebirds (Coliiformes)
TLDR
It is shown that P. bella is a member of the Coliiformes (mousebirds) and represents the latest North American occurrence of a clade with an exclusively African extant distribution and Phylogenetic results imply that a minimum of three mousebird dispersals from Europe to North America occurred during the Early Cenozoic.

UNUSUAL TARSOMETATARSUS OF A MOUSEBIRD FROM THE PALEOGENE OF FRANCE AND THE RELATIONSHIPS OF SELMES PETERS, 1999
TLDR
A nearly complete tarsometatarsus of a mousebird from the middle Eocene to upper Oligocene fissure fillings of the Quercy in France is described, providing further evidence that Selmes is a stem lineage representative of the Coliidae and not a sandcoleid bird as assumed in the original description.

THE FOSSIL RECORD AND EVOLUTION OF MOUSEBIRDS (AVES: COLIIFORMES)
TLDR
A review of all known fossil mousebirds and a new phylogenetic analysis suggest that the Lower Eocene Eocolius is the most basal member of clade Coliiformes, while the Lower–Middle Eocene Sandcoleidae form a basal clade with respect to all other known coliiforms. Expand
Late Oligocene mousebird converges on parrots in skull morphology
TLDR
The new fossil shows that late Oligocene European stem group Coliiformes significantly differed from their extant relatives in morphology and probably also in feeding ecology. Expand
New fossil mousebird (Aves: Coliiformes) with feather preservation provides insight into the ecological diversity of an Eocene North American avifauna
TLDR
A new species of Coliiformes is reported from the early Eocene Fossil Butte Member of the Green River Formation, represented by one of the comparatively few fossils from these deposits preserving carbonized traces of the wing and tail feathering. Expand
New or previously unrecorded avian taxa from the Middle Eocene of Messel (Hessen, Germany)
TLDR
An exceptionally well preserved skeleton of a sandcoleid bird gives new information on the osteology and feathering of sandcoelid birds, and an isolated foot of a gruiform bird is assigned to ldiornis cf. Expand
The mousebirds (Aves: Coliiformes) from the Middle Eocene of Grube Messel (Hessen, Germany)
TLDR
The monophyly of the Coliiformes (Sandcoleidae + Coliidae) is well corroborated with the recognition of ten osteological synapomorphies and the resemblances that exist between the Recent mousebirds and the “higher” non-passeriform and the passeriform birds respectively, most likely are due to convergence.

Skeletal morphology of the middle Eocene swift Scaniacypselus and the evolutionary history of true swifts (Apodidae)

TLDR
The less specialized wing and pectoral girdle morphology suggests that Scaniacypselus was probably not as aerial as extant Apodidae, and the differences in foot morphology indicate that it was more arboreal than its living relatives and had different breeding and roosting habits. Expand
