Morphological coevolution of the pygostyle and tail feathers in Early Cretaceous birds

  title={Morphological coevolution of the pygostyle and tail feathers in Early Cretaceous birds},
  author={Wang Wei and Jingmai K. O’Connor},
The transformation from a long reptilian tail to a shortened tail ending in a pygostyle and accompanied by aerodynamic fanning rectrices is one of the most remarkable adaptations of early avian evolution. However, no fossils directly capture this transition, and information regarding the structural morphology and the early evolution of the pygostyle in Mesozoic birds and their integuments is relatively limited. Here we provide a review of the pygostyle morphology of Early Cretaceous birds with…

Avian tail ontogeny, pygostyle formation, and interpretation of juvenile Mesozoic specimens
It is shown that fusion of distal vertebrae into the pygostyle structure does not occur in extant birds until near skeletal maturity, and mineralization of vertebral processes also occurs long after hatching, demonstrating that avian tail ontogeny is a crucial parameter specifically for the interpretation of Mesozoic specimens, and generally for insights into vertebrale formation.
An unusual bird (Theropoda, Avialae) from the Early Cretaceous of Japan suggests complex evolutionary history of basal birds
This first record of the Early Cretaceous non-ornithothoracine avialan outside of the Jehol Biota is presented and increases the understanding of their diversity and distribution during the time and provides evidence that the evolutionary history of early birds was more complex than previously realised.
Osteohistology of the Scapulocoracoid of Confuciusornis and Preliminary Analysis of the Shoulder Joint in Aves
It is hypothesized that the fused scapulocoracoid of Confuciusornis is secondarily evolved and suggest the primary factor responsible for this morphology may have been a decrease in mechanical stimulation at the glenoid ofconfuciusORNis relative to other volant birds, linked to the unique flight style of this taxon.
Reinterpretation of a previously described Jehol bird clarifies early trophic evolution in the Ornithuromorpha
Close inspection of STM35-3 reveals that the specimen represents a new species not closely related to hongshanornithids, distinguished by large forelimbs that exceed the length of the hindlimbs, robust and narrow coracoids, and a delicate edentulous rostrum.
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.
A new bohaiornithid-like bird from the Lower Cretaceous of China fills a gap in enantiornithine disparity
A new enantiornithine, Musivavis amabilis n. gen. n. sp., is reported from the Lower Cretaceous Jehol Biota in western Liaoning, China. The new taxon is similar to the bohaiornithids in the robust
Distal spinal nerve development and divergence of avian groups
This study shows that tail anatomy is not universal in avians, and suggests several possible scenarios regarding bird evolution, including an independent paleognathous long-tailed ancestor.
The assembly of the avian body plan : a 160-million-year long process
Birds are one of the most successful groups of vertebrates. The origin of birds from their reptilian ancestors is traditionally rooted near the Jurassic “Urvogel” Archaeopteryx, an approach that has
Taxonomic review of the late Cenozoic megapodes (Galliformes: Megapodiidae) of Australia
Diversity of brush-turkeys halved during the Quaternary, matching extinction rates of scrubfowl in the Pacific, and phylogenetic analysis places four extinct taxa in a derived clade with the extant Australo-Papuan brush-Turkeys Talegalla fuscirostris, L. ocellata, Alectura lathami and Aepypodius bruijnii.


Unique caudal plumage of Jeholornis and complex tail evolution in early birds
Jeholornis reveals that tail evolution was complex and not a simple progression from frond to fan, and probably evolved as the result of complex interactions between natural and sexual selective pressures and served both aerodynamic and ornamental functions.
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,
Insight into the evolution of avian flight from a new clade of Early Cretaceous ornithurines from China and the morphology of Yixianornis grabaui
The complete articulated holotype specimen of Yixianornis grabaui, from the Early Cretaceous Jiufotang Formation of Liaoning Province, in north‐eastern China, arguably the best‐preserved basal ornithurine specimen yet discovered, provides the earliest evidence consistent with the presence of extant avian tail feather fanning.
New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers
An analysis of the phylogenetic distribution of pennaceous feathers on the tail, hindlimb and arms of advanced maniraptorans and basal avialans strongly indicates that these structures evolved in a functional context other than flight, most probably in relation to display, as suggested by some previous studies.
A new specimen of the Early Cretaceous bird Hongshanornis longicresta: insights into the aerodynamics and diet of a basal ornithuromorph
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.

The data support the interpretation that the bulbi rectricium independently controls tail fanning; other muscles are neither capable of nor necessary for significant rectricial abduction, thereby allowing the exploitation of a wide range of lift forces.
From baby birds to feathered dinosaurs: incipient wings and the evolution of flight
These findings provide a quantitative, biologically relevant bracket for theropod performance and suggest that protowings could have provided useful aerodynamic function early in maniraptoran history, with improvements in aerodynamic performance attending the evolution of larger wings, more effective feathers, and faster angular velocities.
The Tail of Tyrannosaurus: Reassessing the Size and Locomotive Importance of the M. caudofemoralis in Non‐Avian Theropods
The resulting contractile force and torque estimates presented here indicate a sizable investment in locomotive muscle among theropods with a range of body sizes and give new evidence in favor of greater athleticism, in terms of overall cursoriality, balance, and turning agility.
Insight into diversity, body size and morphological evolution from the largest Early Cretaceous enantiornithine bird
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.
