ABSTRACT We describe the anatomy and bone histology of an enantiornithine specimen from the Early Cretaceous Jehol Group of northeastern China. CNUVB-0903 is larger than most Early Cretaceous enantiornithine birds and also different from all other named taxa. Thus, we erect the new species Zhouornis hani for the new specimen. CNUVB-0903 preserves a suite of new morphologies for the clade. Noteworthy are those of the braincase and occipital region of the skull, which was previously poorly… Expand
New information on the anatomy of the Chinese Early Cretaceous Bohaiornithidae (Aves: Enantiornithes) from a subadult specimen of Zhouornis hani
TLDR
An exquisitely well-preserved specimen from the Lower Cretaceous Jehol Group of northeastern China, which pedal morphology is suggestive of a unique ecological specialization within Enantiornithes. Expand
A new small enantiornithine bird from the Jehol Biota, with implications for early evolution of avian skull morphology
TLDR
The results indicate that the quadratojugal is an inverted L-shaped element, morphologically similar to that of more basal birds Archaeopteryx bavarica, Jeholornis prima, Confuciusornis sanctus and Sapeornis chaoyangensis, contributing to the refinement of the cranial kinesis in early birds. Expand
First species of Enantiornithes from Sihedang elucidates skeletal development in Early Cretaceous enantiornithines
TLDR
The Sihedang locality of the Lower Cretaceous Yixian Formation is the only recognized ornithuromorph-dominated locality in the Jehol Group of north-eastern China and a new taxon Monoenantiornis sihedangia is erected, consistent with the pattern of ossification that occurs in neornithines. Expand
Anatomy of a New Specimen of Piscivorenantiornis inusitatus (Aves: Enantiornithes) from the Lower Cretaceous Jehol Biota
ABSTRACT We describe a new enantiornithine specimen from the Lower Cretaceous Jiufotang Formation of the Jehol Biota, northeastern China, which can be assigned to the species PiscivorenantiornisExpand
Cranial and dental morphology in a bohaiornithid enantiornithine with information on its tooth replacement pattern
  • Di Liu, L. Chiappe, +5 authors Zhaohui Zeng

  • 2022
TLDR
A new and exquisitely preserved specimen of a bohaiornithid enantiornithine from the Lower Cretaceous Jiufotang Formation in Liaoning Province, northeastern China is described, providing novel information on the cranial anatomy of these birds and unprecedented data on their tooth resorption, implantation, and replacement pattern. Expand
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. Expand
New Bohaiornis-like bird from the Early Cretaceous of China: enantiornithine interrelationships and flight performance
TLDR
The anatomy of another “bohaiornithid” species from the 125 million-year-old Yixian Formation of Liaoning Province, China is described and the first assessment of the flight properties of Bohaiornis-like enantiornithines is offered. Expand
New anatomical information on the bohaiornithid Longusunguis and the presence of a plesiomorphic diapsid skull in Enantiornithes
TLDR
The rarely preserved postorbital of the bohaiornithid Longusunguis kurochkini is completely preserved on both sides of the skull, confirming the presence of a complete postorbitals bar in some enantiornithines. Expand
Soft tissue preservation in two new enantiornithine specimens (Aves) from the Lower Cretaceous Huajiying Formation of Hebei Province, China
TLDR
The presence in this new taxon of traits characteristic of younger enantiornithines and the broad phylogenetic spread of the clade during the Huajiying Formation corroborates previous claims that a significant episode of taxonomic differentiation took place prior to the earliest known phases of this clade's evolutionary history. Expand
Yuanjiawaornis viriosus, gen. et sp. nov., a large enantiornithine bird from the Lower Cretaceous of western Liaoning, China
Abstract Here we describe a new enantiornithine bird, Yuanjiawaornis viriosus gen. et sp. nov., based on a nearly complete, mostly articulated postcranial skeleton from the Lower Cretaceous JiufotangExpand

Phylogenetic Support for a Specialized Clade of Cretaceous Enantiornithine Birds with Information from a New Species
ABSTRACT A new species of enantiornithine bird from the Lower Cretaceous Yixian Formation of northeastern China is reported. The new taxon, Shanweiniao cooperorum, possesses several enantiornithineExpand
Phylogenetic support for a specialized clade of Cretaceous enantiornithine birds with information from a new species
TLDR
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. Expand
Juvenile Birds from the Early Cretaceous of China: Implications for Enantiornithine Ontogeny
TLDR
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. Expand
A revision of enantiornithine (Aves: Ornithothoraces) skull morphology
TLDR
A comprehensive overview of the current knowledge of enantiornithine skull anatomy is presented and a number of trophic specializations can be deduced from the range of preserved morphologies, further hinting at the morphological and ecological diversity of the Cretaceous Enantiornithes. Expand
A new, three-dimensionally preserved enantiornithine bird (Aves: Ornithothoraces) from Gansu Province, north-western China
TLDR
The exceptional, three-dimensional preservation of these specimens (compared to the crushed, nearly two-dimensional condition of most other Early Cretaceous avian fossils) reveals new information regarding enantiornithine anatomy, evolution, and diversity. Expand
A New Skull of Gobipteryx minuta (Aves: Enantiornithes) from the Cretaceous of the Gobi Desert
TLDR
The new skull from Ukhaa Tolgod and the reinterpretation of cranial aspects of the previously published material of Gobipteryx minuta and Nanantius valifanovi permit an accurate reconstruction of the palate of this enantiornithine bird, thus adding significant data for understanding the poorly known palatal structure of Mesozoic birds. Expand
Insight into diversity, body size and morphological evolution from the largest Early Cretaceous enantiornithine bird
TLDR
The largest Early Cretaceous enantiornithine bird from north‐east China is reported, which provides evidence that basal members of Enantiornithes share more morphologies with ornithurine birds than previously recognized, and allows a re‐evaluation of a previously proposed hypothesis of competitive exclusion among EarlyCretaceous avian clades. Expand
A New Enantiornithine Bird from the Lower Cretaceous of Western Liaoning, China, and Its Implications for Early Avian Evolution
TLDR
A new enantiornithine bird from the Lower Cretaceous Jiufotang Formation of western Liaoning, China is described, indicating that a carpometacarpal morphology similar to that seen in modern birds probably evolved independently in enantiornsithines and appeared earlier than in Ornithuromorpha, and demonstrates that character evolution in early birds was more complex than previously believed.

A second enantiornithean (Aves: Ornithothoraces) wing from the Early Cretaceous Xiagou Formation near Changma, Gansu Province, People's Republic of China
A new specimen of an enantiornithean bird from the Lower Cretaceous Xiagou Formation of Gansu Province, northwestern China, consists of an articulated distal left humerus, ulna, radius, carpus, andExpand
The skull of a relative of the stem-group bird Mononykus
TLDR
The configuration of the temporal region of the skull and its articulation with the rostrum indicate the capability for prokinetic movement in which flexing occurs at the junction of the upper jaw and neurocranium, and support the idea that prokinesis preceded other types of avian intracranial kinesis.
