The feeding apparatus of Paleogene birds is rarely well-preserved. Here, we describe the earliest known pelican (early Oligocene, Luberon, southeastern France), with its almost complete beak. Morphologically identical to modern pelicans, the new fossil already shows several advanced features unique to extant species of the genus Pelecanus. It probably belongs to the lineage ancestral to all or some of these pelican species. This fossil reveals a remarkable evolutionary stasis in the morphology…

The Earliest Recorded Fossil Pelican, Recovered from the Late Eocene of Wadi Al-Hitan, Egypt
ABSTRACT The Paleogene record of pelicans (Pelecanidae) is represented at present by a single early Oligocene specimen from southeastern France. Here we describe a new pelecanid from the early
First record of fossil birds (Pelecaniformes: Pelecanidae and a probably Odontopterygiformes: Pelagornithidae) from the Upper Miocene of Costa Rica
For the first time, remains of two fossil marine birds are recorded for Costa Rica; these fossils came out from the Upper Miocene Curre Formation. These finds are associated to shallow marine
The earliest Tyrannida (Aves, Passeriformes), from the Oligocene of France
TLDR
One of the few earliest fossil passerines, from the early Oligocene of southern France, and one of the best preserved and most complete, can be conservatively assigned to Tyrannida, a subclade of the New World Tyranni (Suboscines), i.e. of the Tyrannides.
The phylogenetic relationships of the extant pelicans inferred from DNA sequence data.
TLDR
This data rejects the widespread notion that pelicans can be divided into white- and brown-plumaged groups and finds that the species fall into three well-supported clades: an Old World clade of the Dalmatian, Spot-billed, Pink-backed and Australian Pelicans, a New World clades of the American White, Brown and Peruvian Pelicans, and monospecific clade consisting solely of the Great White Pelican.
Lunge feeding in early marine reptiles and fast evolution of marine tetrapod feeding guilds
TLDR
It is reported that the evolution of marine predator feeding guilds, and their trophic structure, proceeded faster than expected after the end-Permian extinction, and a simple recovery to a Permian-like trophics does not explain the biotic changes seen after the Early Triassic.
Phylogenetic Analysis of Pelecaniformes (Aves) Based on Osteological Data: Implications for Waterbird Phylogeny and Fossil Calibration Studies
TLDR
Relationships of extant pelecaniforms inferred from morphology are more congruent with molecular phylogenies than previously assumed, though notable conflicts remain.
The origins of crown group birds: molecules and fossils
TLDR
It is shown how new sequence-based phylogenies may shed light on the relationships of fossils with an unexpected character mosaic, and how such fossils can improve the understanding of character evolution in morphologically disparate avian taxa.
A Pelican Tarsometatarsus (Aves: Pelecanidae) from the Latest Pliocene Siwaliks of India
TLDR
The observation that this tarsometatarsus is morphologically distinct from those of known pelicans provides further support for the distinctiveness of at least one extinct species of pelican from the Siwalik Group sediments.
On the Middle Miocene avifauna of Maboko Island, Kenya ☆
Abstract The Middle Miocene sediments of Maboko Island (Lake Victoria) in western Kenya yielded numerous avian bones, which remained, however, little studied. The significance of this material is
A New Species of Threskiornithidae-Like Bird (Aves, Ciconiiformes) from the Green River Formation (Eocene) of Wyoming
TLDR
This new species represents the first proposed part of Ciconiiformes (and possibly stem-Threskiornithidae) in the Green River Formation of North America and implies that additional lineages within the waterbird assemblage had diverged by the late early Eocene.

Diversification of Neoaves: integration of molecular sequence data and fossils
TLDR
The calibration results suggest that Neoaves, after an initial split from Galloanseres in Mid-Cretaceous, diversified around or soon after the K/T boundary, and show that there is no solid molecular evidence for an extensive pre-Tertiary radiation of Neoaves.
Hummingbird with modern feathering: an exceptionally well-preserved Oligocene fossil from southern France
TLDR
The new fossil reveals that these European Trochilidae were remarkably modern in size, skeletal proportions and the shape of the wing, tail and beak and hyoid bones, and confirms the early acquisition of the abilities of hovering and nectarivory in hummingbirds, probably before the Oligocene.
A Phylogenomic Study of Birds Reveals Their Evolutionary History
TLDR
This study examined ∼32 kilobases of aligned nuclear DNA sequences from 19 independent loci for 169 species, representing all major extant groups, and recovered a robust phylogeny from a genome-wide signal supported by multiple analytical methods.
Fossil birds of the Kibish Formation.
TLDR
Four of the birds are referrable to extant taxa that provide some paleoenvironmental clues for Member I of the Kibish Formation, and two species of pelican, the darter, and the heron indicate the presence of local freshwater bodies, a lake or a slow river, supporting resources of fish.

TLDR
Although the species show considerable morphological diversity, many in fact are notoriously difficult to identify in the field (especially females and immatures).
Processes generating macroevolutionary patterns of morphological variation in birds: a simulation study
TLDR
A computer simulation of cladogenesis and anagenesis based on a genetic and a random walk model (drift) of morphological variation in birds is employed to analyse the possible evolutionary processes behind this pattern.

TLDR
It is suggested that mineral content may be an overlooked component to cranial kinesis in birds.

TLDR
A new framework is emerging for deepening the understanding of evolution and speciation, which provides a plausible multidimensional alternative to the conventional view of rugged adaptive landscapes.
