The evolution of the modern avian digestive system: insights from paravian fossils from the Yanliao and Jehol biotas

  title={The evolution of the modern avian digestive system: insights from paravian fossils from the Yanliao and Jehol biotas},
  author={Jingmai K. O’Connor and Zhonghe Zhou},
The avian digestive system, like other aspects of avian biology, is highly modified relative to other reptiles. Together these modifications have imparted the great success of Neornithes, the most diverse clade of amniotes alive today. It is important to understand when and how aspects of the modern avian digestive system evolved among neornithine ancestors in order to elucidate the evolutionary success of this important clade and to understand the biology of stem birds and their closest…

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.
Investigating Possible Gastroliths in a Referred Specimen of Bohaiornis guoi (Aves: Enantiornithes)
Gastroliths, where preserved, can provide indirect evidence regarding diet in extinct avian and non-avian dinosaurs. Masses of gastroliths consistent with the presence of a gastric mill are preserved
Exceptional avian pellet from the Paleocene of Patagonia and description of its content: a new species of calyptocephalellid (Neobatrachia) anuran
A fossil gastric pellet from the Danian ‘Banco Negro Inferior’ of the Salamanca Formation at Punta Peligro Locality (Chubut, Argentina) and its 3D preserved fossil content is studied, representing a new species of the genus Calyptocephalella.
Diet of Mesozoic toothed birds (Longipterygidae) inferred from quantitative analysis of extant avian diet proxies
Background Birds are key indicator species in extant ecosystems, and thus we would expect extinct birds to provide insights into the nature of ancient ecosystems. However, many aspects of extinct
Integrated phylogenomic and fossil evidence of stick and leaf insects (Phasmatodea) reveal a Permian–Triassic co-origination with insectivores
A Permian to Triassic origin of crown Phasmatodea coinciding with the radiation of early insectivorous parareptiles, amphibians and synapsids is recovered.
Mammal‐bearing gastric pellets potentially attributable to Troodon formosus at the Cretaceous Egg Mountain locality, Two Medicine Formation, Montana, USA
Fossil gastric pellets (regurgitalites) have distinct taphonomic characteristics that facilitate inferences of behavioural ecology in deep time, despite their rarity in the fossil record. Using the
Two emetolite-pterosaur associations from the Late Jurassic of China: showing the first evidence for antiperistalsis in pterosaurs
Knowledge about the pterosaur diet and digestive system is limited, and there is little direct evidence in the fossil record. Here, we report two specimens of the wukongopterid Kunpengopterus
New toothed Early Cretaceous ornithuromorph bird reveals intraclade diversity in pattern of tooth loss
The earliest record of the Ornithuromorpha, which includes crown birds, is currently known from the Early Cretaceous Jehol Biota in north-eastern China. Here we describe a new ornithuromorph bird,
Title: Trophic shift and the origin of birds
Birds are characterized by evolutionary specializations of both locomotion (e.g., flapping flight) and digestive system (toothless, crop, and gizzard), while the potential selection pressures
Trophic shift and the origin of birds

The results suggest that the powered flight and specialized digestive system of birds may have evolved as a result of their tropic shift-associated predation pressure.


Early evolution of the biological bird: perspectives from new fossil discoveries in China
While no skeletal or integumentary features are recognized to define Aves, a partial reconstruction of the biology of Aves very close to its origin is identified: the presence of a crop and the loss of the right ovary.
Exceptional dinosaur fossils reveal early origin of avian-style digestion
Six gastric pellets attributable to the recently discovered Anchiornis suggest that a digestive system resembling that of modern birds was already present in basal members of the Paraves, a clade including troodontids, dromaeosaurids, and birds, and that the evolution of modern avian digestion may have been related to the appearance of aerial locomotion in this lineage.
A new basal bird from China with implications for morphological diversity in early birds
Phylogenetic analyses indicate that Chongmingia zhengi is basal to the dominant Mesozoic avian clades Enantiornithes and Ornithuromorpha, and represents a new basal avialan lineage.
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.

A new ornithurine from the Early Cretaceous of China sheds light on the evolution of early ecological and cranial diversity in birds
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.
Fossil evidence of avian crops from the Early Cretaceous of China
Two Early Cretaceous birds, the basal ornithurine Hongshanornis and a basal avian Sapeornis, demonstrate that an essentially modern avian digestive system formed early in avian evolution.
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,
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
