A new bird from the early Cretaceous Yixian Formation of Liaoning, China is described. This new species, Grabauornis lingyuanensis, shares several synapomorphies with the Enantiornithes. The specimen is relatively well preserved. The skeletal morphology of Grabauornis bears close resemblance to that of other Chinese members of this clade. The brachial index (the ratio between the lengths of humerus and ulna) is 0.95, which is close to the average for enantiornithine birds. It indicates that…

Chapter 2 The fossil record of Mesozoic and Paleocene pennaraptorans
An unabated surge of new and important discoveries continues to transform knowledge of pennaraptoran biology and evolution amassed over the last 150+ years. This chapter summarizes progress made thus
The plumage and colouration of an enantiornithine bird from the early cretaceous of china
A new basal enantiornithine bird specimen recovered from the Early Cretaceous Jiufotang Formation of Liaoning Province in northeastern China is described and data on skeletal ontogeny in the Bohaiornithidae is provided as well as evidence for intraspecific communication functions of plumage.
The Plumage of Basal Birds
Overall, early birds show a trend towards the reduction of the distal hindlimb feathers present in closely related nonavian dinosaurs, however, well-developed tarsometatarsal feathers are present in Sapeornis and two exceptionally well-preserved enantiornithine specimens indicate this group was diverse in thedistal extent of their hindlimB plumage, including at least one lineage with feathered pedal digits.

Birds are some of the most diverse organisms on Earth, with species inhabiting a wide variety of niches across every major biome. As such, birds are vital to our understanding of modern ecosystems.
A new bohaiornithid-like bird from the Lower Cretaceous of China fills a gap in enantiornithine disparity
Alternative scenarios based on progressive downweighting of the homoplastic characters support more basal placements of the pengornithids among Enantiornithes, but do not alter the affinity of Musivavis as a member of the “bohaiornithid-grade" group.


Description of a new enantiornithine bird from the Early Cretaceous of Hebei, northern China
This paper describes a new enantiornithine fossil bird, Vescornis hebeiensis, nov. sp. from the Early Cretaceous of China. We refer Vescornis to the crown clade Euenantiornithes based on several
A new Early Cretaceous enantiornithine bird reported from Liaoning, northeast China is about the size of Cathayornis but is more primitive, with advanced features of the scapula and the wing that suggest a powerful flapping flight capability.
A primitive enantiornithine bird and the origin of feathers.
A fossil enantiornithine bird, Protopteryx fengningensis gen. et sp. nov., was collected from the Early Cretaceous Yixian Formation of Northern China. It provides fossil evidence of a triosseal canal
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.
Anatomy of the early cretaceous bird Eoenantiornis buhleri (Aves : Enantiornithes) from China
The anatomy of Eoenantiornis reveals many morphological characters previously unknown for enantiornithine birds, such as presence of a distinct facet for the intramandibular articulation between the dentary and postdentary bones.
A New Enantiornitine Bird with Four Long Rectrices from the Early Cretaceous of Northern Hebei, China
This is the first record of Mesozoic birds in having four long rectrices, which may represent morphologically a secondary sexual character, an intermediate stage from elongated scale to branched feather, and possess functional advantage in supplementing the lifting surface to compensate the unskilled flight.
New Early Cretaceous fossil from China documents a novel trophic specialization for Mesozoic birds
The morphology of the skull suggests that Longirostravis had a probing feeding behavior, a specialization previously unknown for Enantiornithes, and provides the first evidence in support of the existence of such a foraging behavior among basal lineages of Mesozoic birds.
Neuquenornis volans, a new Late Cretaceous bird (Enantiornithes: Avisauridae) from Patagonia, Argentina
The structure of the wing and pectoral girdle of Neuquenornis indicates that it was an active flyer, an aptitude also inferred for the El Brete enantiornithines from the Upper Cretaceous Lecho Formation of northwestern Argentina.
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.
