New Early Cretaceous fossil from China documents a novel trophic specialization for Mesozoic birds

We report on a new Mesozoic bird, Longirostravis hani, from the Early Cretaceous Jehol Biota of northeastern China. The new taxon has a long, slender rostrum and mandible, and a small number of rostralmost teeth. Postcranial characters such as a furcular ramus wider ventrally than dorsally, a centrally concave proximal margin of the humeral head, and a minor metacarpal that projects distally more than the major metacarpal, support the placement of Longirostravis within euenantiornithine… 
Phylogenetic support for a specialized clade of Cretaceous enantiornithine birds with information from a new species
Shanweiniao provides new information on the anatomy of longipterygids, and preserves a rectricial morphology previously unknown to enantiornithines, with at least four tail feathers closely arranged, which supports the hypothesis that enantiORNithines were strong fliers and adds to the diversity of known tail morphologies of these Cretaceous birds.
A New Enantiornithine Bird from the Lower Cretaceous of Western Liaoning, China
ABSTRACT A new enantiornithine bird, Bohaiornis guoi, gen. et sp. nov., is described in this paper. The holotype, presumably a sub-adult, is a complete, fully articulated skeleton from the Lower
A New Robust Enantiornithine Bird from the Lower Cretaceous of China with Scansorial Adaptations
ABSTRACT We describe a new enantiornithine bird, Fortunguavis xiaotaizicus, gen. et sp. nov, from the Lower Cretaceous lacustrine deposits of the Jiufotang Formation in northeastern China. The new
A New Specimen of Large-Bodied Basal Enantiornithine Bohaiornis from the Early Cretaceous of China and the Inference of Feeding Ecology in Mesozoic Birds
It is hypothesized that cranial morphology as well as the number and shape of the preserved stones in Bohaiornis may be most consistent with a raptorial ecology previously unknown for Enantiornithes and considered rare for Avialae.
A new Enantiornithine bird from the Late Cretaceous of the Gobi desert
The combination of phylogeny and functional interpretation suggests that this new fossil bird is a representative of a flightless lineage, providing the first evidence of a trend towards more limited flying capabilities among Enantiornithes, a group of Cretaceous birds otherwise believed to be represented by competent fliers.
Novel evolution of a hyper-elongated tongue in a Cretaceous enantiornithine from China and the evolution of the hyolingual apparatus and feeding in birds.
The fossil of a new enantiornithine bird from the Lower Cretaceous Jiufotang Formation in Liaoning Province, northeastern China preserves a few important skeletal features previously unknown among early stem and extant birds, including an extremely elongate bony hyoid element (only slightly shorter than the skull), combined with a short cranial rostrum.
New Species of Enantiornithes (Aves: Ornithothoraces) from the Qiaotou Formation in Northern Hebei, China
The new taxon possesses a large postorbital with a long tapering jugal process indicating that some enantiornithines may have had a fully diapsid skull, as in Confuciusornis, and likely represents a previously unknown trophic specialization within Enantiornithes.
Juvenile Birds from the Early Cretaceous of China: Implications for Enantiornithine Ontogeny
The skeletal morphology of three nearly complete early juvenile avians from the renowned Early Cretaceous Yixian Formation of Liaoning Province in northeastern China are reported on, suggesting that fledging occurred very early in ontogeny, thus supporting a precocial or highly precocial strategy for enantiornithine hatchlings.
A Morphological Study of the First Known Piscivorous Enantiornithine Bird from the Early Cretaceous of China
It is shown that this fish-eating enantiornithine bird from the Lower Cretaceous Jiufotang Formation of Liaoning Province, northeastern China represents a new taxon, Piscivorenantiornis inusitatus, gen. et sp.
The first Mesozoic heterodactyl bird from China
Well-preserved alula feathers and a heterodactyl foot provide strong evidence for the arboreal habit of Dalingheornis, highlighting again the evolutionary relationship between birds and non-avian theropods.


Fossil birds from the Mesozoic of Gondwana are exceedingly rare (Chiappe, 1996a; Forster et al., 1998; Clarke and Chiappe, 2001). We report on a new avian specimen from the upper Cretaceous of
An exceptionally preserved Lower Cretaceous ecosystem
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight.
Early Evolution of Avian Flight and Perching: New Evidence from the Lower Cretaceous of China
Modern avian flight function and perching capability must have evolved in small-bodied birds in inland habitats not long after Archaeopteryx.
Early diversification of birds: Evidence from a new opposite bird
The new bird represents a new ecological type different from all known members of Enantiornithes, and shows that enantiornithines had probably originated earlier than the Early Cretaceous, or this group had experienced a rapid radiation right after it first occurred in the early EarlyCretaceous.
An Early Cretaceous bird from Spain and its implications for the evolution of avian flight
A new, exquisitely preserved, bird from the Lower Cretaceous Konservat-Lagerstätte of Las Hoyas (Cuenca, Spain) which provides evidence for the oldest known alula (bastard wing) and the recognition of a new enantiornithine taxon, Eoalulavishoyasi.
Archaeoraptor's better half
A new specimen that is also referable to this species, and which has its gut contents preserved, indicates that the principal part of this false raptor dinosaur–bird fossil is in fact a fish-eating bird.
A long-tailed , seed-eating bird from the Early Cretaceous of China

The origin and evolution of birds
Ornithologist and evolutionary biologist Alan Feduccia, author of "Age of Birds," here draws on fossil evidence and studies of the structure and biochemistry of living birds to present knowledge and data on avian evolution and propose a model of this evolutionary process.
Further support for a Cretaceous age for the feathered-dinosaur beds of Liaoning,China:New 40Ar÷39Ar dating of the Yixian and Tuchengzi Formations
We report new 40Ar÷39Ar dating results obtained from total fusion and incremental-heating analyses of sanidine and biotite from three tuffs found interbedded within the fossil-bearing deposits of
