A complete redescription of Cathayornis caudatus Hou, 1997 is provided based on new information from a resin cast of the holotype, leading to reinterpretation of many morphological features of this initially poorly diagnosed taxon. Detailed comparisons across various specimens referred to Cathayornithidae Zhou et al., 1992 indicate that Sinornis santensis, Cathayornis yandica, C. caudatus and Eocathayornis walkeri are valid taxa, but that C. chabuensis should be regarded as a nomen dubium.

A new enantiornithine (Aves: Ornithothoraces) with completely fused premaxillae from the Early Cretaceous of China
We report a new small enantiornithine, Shangyang graciles gen. et sp. nov., based on a nearly complete and articulated skeleton from the Lower Cretaceous Jiufotang Formation of Liaoning Province,Expand
A new small enantiornithine bird from the Jehol Biota, with implications for early evolution of avian skull morphology
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
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
Early Cretaceous Enantiornithine Birds (Aves, Ornithothoraces) and Establishment of the Ornithuromorpha Morphological Type
A new hypothesis concerning the phylogenetic position of Pengornithidae is proposed, which implies that the fan-shaped tail and modern-type humeral joint was formed once in the early evolution of birds. Expand
New Bohaiornis-like bird from the Early Cretaceous of China: enantiornithine interrelationships and flight performance
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
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 thusExpand
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. Expand
Soft tissue preservation in two new enantiornithine specimens (Aves) from the Lower Cretaceous Huajiying Formation of Hebei Province, China
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
New anatomical information on the bohaiornithid Longusunguis and the presence of a plesiomorphic diapsid skull in Enantiornithes
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
A previously undescribed specimen reveals new information on the dentition of Sapeornis chaoyangensis
The well-preserved skull of a juvenile specimen of Sapeornis, STM 16-18, is described and it is hypothesized that this morphology captures an early stage in dental reduction and indicates that in at least some avian lineages, the loss of teeth was gradual. Expand


A reassessment of Sinornis santensis and Cathayornis yandica (Aves: Enantiornithes). In Proceedings of the VII International Meeting of the Society of Avian Paleontology and Evolution, ed. W.E. Boles and T.H. Worthy
This paper conducts a detailed morphological review of both holotype specimens of C. yandica and S. santensis and concludes that the two birds constitute valid and distinct branches in the diverse enantiornithine evolutionary radiation. Expand
A redescription of Chaoyangia beishanensis (Aves) and a comprehensive phylogeny of Mesozoic birds
Unique among ornithurines, Chaoyangia possesses two dorsal processes on the ischium, and thus remains a valid taxon and is included in a cladistic analysis to test morphological hypotheses regarding its systematic position. Expand
A new piscivorous ornithuromorph from the Jehol Biota
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. Expand
A new diverse enantiornithine family (Bohaiornithidae fam. nov.) from the Lower Cretaceous of China with information from two new species
Two new enantiornithine birds,Parabohaiornis martini gen. et sp. nov.,and Longusunguis kurochkini gen. et sp. nov.,are reported here based on three nearly complete skeletons from the Lower CretaceousExpand
New enantiornithine bird (Aves, Ornithothoraces) from the Late Cretaceous of NW Argentina
A new enantiornithine bird, Intiornis inexpectatus gen. et sp. nov, is described here. It is based on a partial hind limb found in beds of the Upper Cretaceous Las Curtiembres Formation (Campanian),Expand
Anatomy of the Early Cretaceous Enantiornithine Bird Rapaxavis pani
The holotype and only known specimen of Rapaxavis pani is redescribed here after more extensive preparation and reveals important information for better understanding the anatomy and phylogenetic relationships of longipterygids, in particular, as well as basal birds as a whole. Expand
A reappraisal of Boluochia zhengi (Aves: Enantiornithes) and a discussion of intraclade diversity in the Jehol avifauna, China
It is suggested that the trophic specialization that characterizes longipterygids may have been a major factor contributing to the success of this clade of Early Cretaceous enantiornithines. Expand
