A comprehensive phylogeny of birds Aves using targeted next-generation DNA sequencing. Email alerts Article activity alert. Primitive bird tails underwent significant alteration, most notably reduction of the number of caudal vertebrae and fusion of the distal caudal vertebrae into an ossified pygostyle. The tail of extant birds, for example, functions to provide lift, braking, and turning surfaces for controlled flight [ 32 — 36 ], but is decoupled from the hind limb and has lost its ancestral contributions to terrestrial as opposed to aerial locomotion. While there is no equivalent gain-of-function mouse mutant, loss-of-function mutations in either Irx1 or Irx2 in the mouse do not cause posterior truncation or fused vertebrae, emphasizing an important caveat with this study that mutation of the same genes can be manifested differently depending on the nature of the mutation.

An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. Finally, increased apoptosis at the termination of somitogenesis removes all remaining progenitor cells. About this book Knowledge of the evolutionary history of birds has much improved in recent decades. Extant bird tails consist proximally of a small series of unfused caudal vertebrae with a high range of motion. Third, since long tails hinder flight, and flight mechanics evolved primarily with short tails [ 36 ], reintroduction of long tails would have likely impeded survival. Figure 5. While these mutations generally preserve the overall number of vertebral elements, some Hox gene disruptions can increase or more commonly decrease total vertebrae numbers reviewed in [ 78 ]. The three-inch skull, being delicate, was not even extricated from the rock. Stronger biting forces as well as the characteristic prey manipulation behavior of extant rollers may account for some of the observed differences in the cranial and vertebral morphology of the fossil and extant taxa, but the exact functional correlations remain elusive. Bird origins anew. Modern birds originated in the Late Cretaceous, and it has become increasingly apparent that the final 20 million years of the age of the dinosaurs 86 million to 66 million years ago was a pivotal time in avian evolutionary history.

  • Uropygial Gland in Birds
    UROPYGIAL GLAND IN BIRDS Prepared by Dr. Subhadeep Sarker Associate Professor, Department of Zoology, Serampore College Occurrence and Location: • The uropygial gland, often referred to as the oil or preen gland, is a bilobed gland and is found at the dorsal base of the tail of most psittacine birds. • The uropygial gland is a median dorsal gland, one per bird, in the synsacro-caudal region. A half moon-shaped row of feather follicles of the upper median and major tail coverts externally outline its position. • The uropygial area is located dorsally over the pygostyle on the midline at the base of the tail. • This gland is most developed in waterfowl but very reduced or even absent in many parrots (e.g. Amazon parrots), ostriches and many pigeons and doves. Anatomy: • The uropygial gland is an epidermal bilobed holocrine gland localized on the uropygium of most birds. • It is composed of two lobes separated by an interlobular septum and covered by an external capsule. • Uropygial secretory tissue is housed within the lobes of the gland (Lobus glandulae uropygialis), which are nearly always two in number. Exceptions occur in Hoopoe (Upupa epops) with three lobes, and owls with one. Duct and cavity systems are also contained within the lobes. • The architectural patterns formed by the secretory tubules, the cavities and ducts, differ markedly among species. The primary cavity can comprise over 90% of lobe volume in the Oilbird (Steatornis caripensis) and some woodpeckers and pigeons. • The gland is covered by a circlet or tuft of down feathers called the uropygial wick in many birds.

Chiappe3, Nathan Carroll3, Kimball L. Garrett4, Bino Accepted: 23 May 2018 Varghese5, Alida Bailleul6,7, Jingmai K. O’Connor 7, Susan C. Chapman 8 & John R. Horner1,9 Published: xx xx xxxx The avian tail played a critical role in the evolutionary transition from long- to short-tailed birds, yet its ontogeny in extant birds has largely been ignored. This defcit has hampered eforts to efectively identify intermediate species during the Mesozoic transition to short tails. Here we show 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. Evidence for post-hatching pygostyle formation is also demonstrated in two Cretaceous specimens, a juvenile enantiornithine and a subadult basal ornithuromorph. These fndings call for reinterpretations of Zhongornis haoae, a Cretaceous bird hypothesized to be an intermediate in the long- to short-tailed bird transition, and of the recently discovered coelurosaur tail embedded in amber. Zhongornis, as a juvenile, may not yet have formed a pygostyle, and the amber-embedded tail specimen is reinterpreted as possibly avian. Analyses of relative pygostyle lengths in extant and Cretaceous birds suggests the number of vertebrae incorporated into the pygostyle has varied considerably, further complicating the interpretation of potential transitional species. In addition, this analysis of avian tail development reveals the generation and loss of intervertebral discs in the pygostyle, vertebral bodies derived from diferent kinds of cartilage, and alternative modes of caudal vertebral process morphogenesis in birds.

  • At the Root of the Early Penguin Neck: a Study of the Only Two Cervicodorsal Spines Recovered from the Eocene of Antarctica Piotr Jadwiszczak

The new specimen is smaller E-mail: [email protected] than the counterpart elements in recent king penguins, whereas the second series belonged to a large-bodied penguin from the genus Palaeeudyptes. It had been assigned by earlier researchers to P. gunnari (a species of ‘‘giant’’ penguins) and a Bayesian analysis*a Bayes factor approach based on size of an associated tarsometatarsus*strongly supported such an assignment. Morphological and functional studies revealed that mobility within the aforementioned segment probably did not differ substantially between extant and studied fossil penguins. There were, however, intriguing morphological differences between the smaller fossil specimen and the comparative material related to the condition of the lateral excavation in the first cervicodorsal vertebra and the extremely small size of the intervertebral foramen located just prior to the first ‘‘true’’ thoracic vertebra.

  • Fossil Birds of New Zealand This Appendix Lists Birds Recorded As Fossils in New Zealand from Sediments Older Than the Middle Pleistocene (≥1 Ma)
    Text extracted from Gill B.J.; Bell, B.D.; Chambers, G.K.; Medway, D.G.; Palma, R.L.; Scofield, R.P.; Tennyson, A.J.D.; Worthy, T.H. 2010. Checklist of the birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th edition. Wellington, Te Papa Press and Ornithological Society of New Zealand. Pages 323 & 326-327. Fossil Birds of New Zealand This Appendix lists birds recorded as fossils in New Zealand from sediments older than the Middle Pleistocene (≥1 Ma). It therefore includes material from the Kaimatira Pumice Sand of the Kai Iwi Group (Oxygen Isotope Stage 25–27, c. 1 Ma) found at Marton (Worthy 1997a). All younger fossil birds are members of the Recent fauna, are of species that persisted to human arrival and are covered in the main text. The pre-Pleistocene record of birds in New Zealand has until recently comprised mainly penguins, as reviewed by Fordyce (1991b). No marine taxa other than penguins and pelagornithids had been described, but rare procellariid bones were known (Worthy & Holdaway 2002). The record of Tertiary terrestrial avifauna was until recently restricted to two undescribed anatids from the Miocene of Otago (Fordyce 1991b). Renewed investigations of the Miocene deposits at St Bathans, Otago, have recovered a rich avifauna from lacustrine deposits comprising at least 24 taxa (Worthy et al. 2007). In addition to the taxa named below (a diving petrel and several waterfowl), the St Bathans Fauna includes the following unnamed taxa: ratite (eggshell), two rails (Rallidae), a possible aptornithid (?Aptornithidae), three parrots (Psittacidae), an eagle (Accipitridae), two pigeons (Columbidae), at least three waders (Charadriiformes), and several passerines (Passeriformes).

  • A Late Cretaceous Diversification of Asian Oviraptorid Dinosaurs
    www.nature.com/scientificreports OPEN A Late Cretaceous diversification of Asian oviraptorid dinosaurs: evidence from a new species Received: 10 March 2016 Accepted: 06 October 2016 preserved in an unusual posture Published: 10 November 2016 Junchang Lü1, Rongjun Chen2, Stephen L. Brusatte3, Yangxiao Zhu2 & Caizhi Shen1 Oviraptorosaurs are a bizarre group of bird-like theropod dinosaurs, the derived forms of which have shortened, toothless skulls, and which diverged from close relatives by developing peculiar feeding adaptations. Although once among the most mysterious of dinosaurs, oviraptorosaurs are becoming better understood with the discovery of many new fossils in Asia and North America. The Ganzhou area of southern China is emerging as a hotspot of oviraptorosaur discoveries, as over the past half decade five new monotypic genera have been found in the latest Cretaceous (Maastrichtian) deposits of this region. We here report a sixth diagnostic oviraptorosaur from Ganzhou, Tongtianlong limosus gen. et sp. nov., represented by a remarkably well-preserved specimen in an unusual splayed-limb and raised- head posture. Tongtianlong is a derived oviraptorid oviraptorosaur, differentiated from other species by its unique dome-like skull roof, highly convex premaxilla, and other features of the skull. The large number of oviraptorosaurs from Ganzhou, which often differ in cranial morphologies related to feeding, document an evolutionary radiation of these dinosaurs during the very latest Cretaceous of Asia, which helped establish one of the last diverse dinosaur faunas before the end-Cretaceous extinction. Oviraptorosaurs are some of the most unusual dinosaurs. These bird-like, feathered theropods diverged dra- matically from their close cousins, evolving shortened toothless skulls with a staggering diversity of pneumatic cranial crests in derived forms1.

  • Anatomy of the Early Cretaceous Enantiornithine Bird Rapaxavis Pani
    Anatomy of the Early Cretaceous enantiornithine bird Rapaxavis pani JINGMAI K. O’CONNOR, LUIS M. CHIAPPE, CHUNLING GAO, and BO ZHAO O’Connor, J.K., Chiappe, L.M., Gao, C., and Zhao, B. 2011. Anatomy of the Early Cretaceous enantiornithine bird Rapaxavis pani. Acta Palaeontologica Polonica 56 (3): 463–475. The exquisitely preserved longipterygid enantiornithine Rapaxavis pani is redescribed here after more extensive prepara− tion. A complete review of its morphology is presented based on information gathered before and after preparation. Among other features, Rapaxavis pani is characterized by having an elongate rostrum (close to 60% of the skull length), rostrally restricted dentition, and schizorhinal external nares. Yet, the most puzzling feature of this bird is the presence of a pair of pectoral bones (here termed paracoracoidal ossifications) that, with the exception of the enantiornithine Concornis lacustris, are unknown within Aves. Particularly notable is the presence of a distal tarsal cap, formed by the fu− sion of distal tarsal elements, a feature that is controversial in non−ornithuromorph birds. The holotype and only known specimen of Rapaxavis pani thus reveals important information for better understanding the anatomy and phylogenetic relationships of longipterygids, in particular, as well as basal birds as a whole.

Notably, Chiappeavis preserves a primitive palatal morphology in which the vomers reach the premaxillae similar to Archaeopteryx but unlike the condition in the Late Cretaceous enantiornithine Gobipteryx. If rectricial bulbs were present, pengornithid pygostyle morphology suggests they were minimally developed. We estimate the lift generated by the tail fan preserved in this specimen and compare it to the tail fans preserved in other Early Cretaceous birds. Aerodynamic models indicate the tail of Chiappeavis produced less lift than that of sympatric ornithuromorphs. This information provides a possible explanation for the absence of widespread aerodynamic tail morphologies in the Enantiornithes.
