An ornithurine bird, Hongshanornis longicresta gen. et sp. nov., represented by a nearly complete and articulated skeleton in full plumage, has been recovered from the lacustrine deposits of the Lower Cretaceous Jehol Group in Inner Mongolia, northeast China. The bird had completely reduced teeth and possessed a beak in both the upper and lower jaws, representing the earliest known beaked ornithurine. The preservation of a predentary bone confirms that this structure is not unique to… 

Figures and Topics from this paper

A new ornithurine from the Early Cretaceous of China sheds light on the evolution of early ecological and cranial diversity in birds
TLDR
It is found that, consistent with a proposed developmental shift in cranial ontogeny late in avialan evolution, this elongate rostrum in Changzuiornis ahgmi is achieved through elongation of the maxilla while the premaxilla remains only a small part of rostral length.
The oldest record of ornithuromorpha from the early cretaceous of China
Ornithuromorpha is the most inclusive clade containing extant birds but not the Mesozoic Enantiornithes. The early evolutionary history of this avian clade has been advanced with recent discoveries
A new basal ornithuromorph bird (Aves: Ornithothoraces) from the Early Cretaceous of China with implication for morphology of early Ornithuromorpha
TLDR
A comprehensive phylogenetic analysis resolved the new taxon in a basal position that is only more derived than Archaeorhynchus and Jianchangornis among ornithuromorphs, increasing the morphological diversity of basal ornithuomorphs.
A NEW BASAL ORNITHURINE BIRD(JIANCHANGORNIS MICRODONTA GEN.ET SP.NOV.) FROM THE LOWER CRETACEOUS OF CHINA
TLDR
The discovery of a new basal ornithurine from the Lower Cretaceous Jiufotang Formation of Jianchang, Liaoning, China further shows that the diversification of the Ornithurae is probably no less than the enantiornithes, and the near lakeshore adaptation had definitely played a key role in the early ornithURine radiation.
A New Ornithuromorph (Aves: Ornithothoraces) Bird from the Jehol Group Indicative of Higher-Level Diversity
TLDR
The discovery of a new bird from the Lower Cretaceous Yixian Formation, Liaoning Province, China, which represents a new species, but bears similarities to Hongshanornis longicresta from the same formation of Inner Mongolia, and represents a clade of specialized ‘shorebirds’ whose elongate hindlimbs indicate ecological adaptations different from those of other Jehol ornithuromorphs.
A new piscivorous ornithuromorph from the Jehol Biota
TLDR
The preservation of fish bones ventral to the dentary and in the stomach provides direct evidence that the new species was piscivorous – previously only reported in Yanornis, and as in some living birds, was capable of moving food bidirectionally through the alimentary canal.
The First Enantiornithine Bird from the Upper Cretaceous of China
TLDR
Histological study shows that the bones of Parvavis were composed of parallelfibered bone tissue without lines of arrested growth, and indicated that growth rate had slowed but had not stopped at any stage prior to death, and the new bird was probably close to adult body size at the time of death.
A new advanced ornithuromorph bird from Inner Mongolia documents the northernmost geographic distribution of the Jehol paleornithofauna in China
ABSTRACT We describe a new taxon of advanced ornithuromorph bird, Khinganornis hulunbuirensis gen. et sp. nov., from the previously unreported Pigeon Hill locality of the Lower Cretaceous Longjiang
A new specimen of the Early Cretaceous bird Hongshanornis longicresta: insights into the aerodynamics and diet of a basal ornithuromorph
TLDR
Most notable are the well-preserved wings and feathered tail of DNHM D2945/6, which afford an accurate reconstruction of aerodynamic parameters indicating that as early as 125 million years ago, basal ornithuromorphs had evolved aerodynamic surfaces comparable in size and design to many modern birds, and flight modes alike to those of some small living birds.
Anatomy of the Basal Ornithuromorph Bird Archaeorhynchus spathula from the Early Cretaceous of Liaoning, China
TLDR
These new specimens are subadult: together with the holotype of Archaeorhynchus, they constitute the entire Early Cretaceous record of subadult ornithuromorphs and reveal important information regarding the ontogeny of this group.

A beaked bird from the Jurassic of China
TLDR
As the first Jurassic birds to be described from outside Germany, they show that birds with long fingers terminating in large recurved claws were widely distributed and are not found in the Early Cretaceous sediments of the same region, where there is a diverse assemblage of more advanced flying birds with smaller fingers and claws.
A long-tailed, seed-eating bird from the Early Cretaceous of China
The lacustrine deposits of the Yixian and Jiufotang Formations in the Early Cretaceous Jehol Group in the western Liaoning area of northeast China are well known for preserving feathered dinosaurs,

Fossil that fills a critical gap in avian evolution
TLDR
The new taxon, Apsaravis ukhaana, is the best-preserved specimen of a Mesozoic ornithurine bird discovered in over a century and provides data important for assessing morphological evolution across Avialae, with implications for the monophyly of Enantiornithes and Sauriurae.
Anatomy of the primitive bird Sapeornis chaoyangensis from the Early Cretaceous of Liaoning, China
Two new, nearly completely articulated skeletons of Sapeornis chaoyangensis provide much new information about the anatomy of this basal avian, particularly in the skull, pectoral girdle, forelimb,
Early diversification of birds: Evidence from a new opposite bird
TLDR
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.
Cretaceous age for the feathered dinosaurs of Liaoning, China
TLDR
The results of this dating study indicate that the lower Yixian fossil horizons are not Jurassic but rather are at least 20 Myr younger, placing them within middle Early Cretaceous time.
The origin and early evolution of birds: discoveries, disputes, and perspectives from fossil evidence
TLDR
Significant size and morphological differences and variation in flight capabilities, ranging from gliding to powerful flight among early birds, highlight the diversification of birds in the Early Cretaceous.
New Early Cretaceous fossil from China documents a novel trophic specialization for Mesozoic birds
TLDR
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.
