Here we provide a detailed comparison of the anatomy of Ambiortus relative to other known Early Cretaceous ornithuromorphs from the Chinese Jehol Group and Xiagou Formation. We include new information on Ambiortus from a previously undescribed slab preserving part of the sternum. Ambiortus is superficially similar to Gansus yumenensis from the Aptian Xiagou Forma tion but shares more morphological features with Yixianornis grabaui (Ornithuromorpha: Songlingorni thidae) from the Jiufotang Formation of the Jehol Group. In general, the mosaic pattern of character distri bution among early ornithuromorph taxa does not reveal obvious relationships between taxa. Ambiortus was placed in a large phylogenetic analysis of Mesozoic birds, which confirms morphological observations and places Ambiortus in a polytomy with Yixianornis and Gansus.

Description of the skull of the genus Syluiornis Poplin, 1980 (Aves, Galliformes, Sylviornithidae new family), a giant extinct bird from the Holocene of New Caledonia. In ALCOVER, J.A. & BaVER, P. (eds.): Proceedings of the International Symposium "Insular Vertebrate Evolution: the Palaeontological Approach': Monografies de la Societat d'Història Natural de les Balears, lZ: Z05-118. Resum El crani de Sylviornismostra una articulació craniarostral completament mòbil, amb dos còndils articulars situats sobre el rostrum, el qual s'insereix al crani en dues superfícies articulars allargades. La presència de dos procesos rostropterigoideus sobre el basisfenoide del rostrum i la forma dels palatins permet confirmar que aquest gènere pertany als Galliformes, però les característiques altament derivades del crani justifiquen el seu emplaçament a una nova família, extingida, Sylviornithidae. El crani de Syluiornis està extremadament eixamplat i dorsoventralment aplanat, mentre que el rostrum és massís, lateralment comprimit, dorsoventralment aixecat i mostra unes cristae tomiales molt fondes. El rostrum exhibeix un ornament ossi gran. La mandíbula mostra una símfisi molt allargada, les branques laterals també presenten unes cristae tomiales fondes, i la part posterior de la mandíbula és molt gruixada. Es discuteix el possible origen i l'alimentació de Syluiornis. Paraules clau: Aves, Galliformes, Extinció, Holocè, Nova Caledònia. Abstract The skull of Syluiornis shows a completely mobile craniorostral articulation, with two articular condyles situated on the rostrum, which insert into two elongated articular surfaces on the cranium. -
A Classification of the Rallidae
A CLASSIFICATION OF THE RALLIDAE STARRY L. OLSON HE family Rallidae, containing over 150 living or recently extinct species T and having one of the widest distributions of any family of terrestrial vertebrates, has, in proportion to its size and interest, received less study than perhaps any other major group of birds. The only two attempts at a classifi- cation of all of the recent rallid genera are those of Sharpe (1894) and Peters (1934). Although each of these lists has some merit, neither is satisfactory in reflecting relationships between the genera and both often separate closely related groups. In the past, no attempt has been made to identify the more primitive members of the Rallidae or to illuminate evolutionary trends in the family. Lists almost invariably begin with the genus Rdus which is actually one of the most specialized genera of the family and does not represent an ancestral or primitive stock. One of the difficulties of rallid taxonomy arises from the relative homo- geneity of the family, rails for the most part being rather generalized birds with few groups having morphological modifications that clearly define them. As a consequence, particularly well-marked genera have been elevated to subfamily rank on the basis of characters that in more diverse families would not be considered as significant. Another weakness of former classifications of the family arose from what Mayr (194933) referred to as the “instability of the morphology of rails.” This “instability of morphology,” while seeming to belie what I have just said about homogeneity, refers only to the characteristics associated with flightlessness-a condition that appears with great regularity in island rails and which has evolved many times. -

The status of CASG 71892 as the oldest known record of either of the two spp. of Uria was recently confirmed by the review of Watanabe et al. (2016). The younger of the two marine transgressions at the Tolstoi Point corresponds to the Bigbendian transgression (Olson, 2013), which contains the Gauss-Matuyama magnetostratigraphic boundary (Kaufman and Brigham-Grette, 1993). Attempts to date this reversal have been recently reviewed by Ohno et al. (2012); Singer (2014), and Head (2019). In particular, Deino et al. (2006) were able to tightly bracket the age of the reversal using high-precision 40Ar/39Ar dating of two tuffs in normally and reversely magnetized lacustrine sediments from Kenya, obtaining a value of 2.589 ± 0.003 Ma. -
A Loon Leg (Aves, Gaviidae) with Crocodilian Tooth from the Late Oligocene of Germany
A Loon Leg (Aves, Gaviidae) with Crocodilian Tooth from the Late Oligocene of Germany GERALD MAYR1* AND MARKUS POSCHMANN2 1Forschungsinstitut Senckenberg, Sektion Ornithologie, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany 2Generaldirektion Kulturelles Erbe RLP, Direktion Landesarchäologie, Referat Erdgeschichte, Große Langgasse 29, D-55116 Mainz, Germany *Corresponding author; E-mail: [email protected] Abstract.—The first late Oligocene fossil record of a loon (Gaviiformes) is described from the lacustrine depos- its of the German locality Enspel. The specimen is an isolated foot, which is associated with a crocodilian tooth. The fossil belongs to a species about half the size of the smallest extant loon, and is morphologically most similar to the Paleogene taxon Colymboides. In all probability it constitutes the prey remains of a crocodilian, which is of particular significance because the distribution ranges of loons and crocodilians hardly overlap today. The Enspel palaeocli- mate was warm-temperate and subtropical, and the Enspel specimen and other Paleogene fossils of gaviiform birds raise the, as yet, unanswered question of why loons largely disappeared from inland habitats of the warmer regions.

California Clapper Rail (Rallus Longirostris Obsoletus) 5-Year Review
California clapper rail (Rallus longirostris obsoletus ) 5-Year Review: Summary and Evaluation Photo by Allen Edwards U.S. Fish and Wildlife Service Sacramento Fish and Wildlife Office Sacramento, California April 2013 5-YEAR REVIEW California clapper rail (Rallus longirostris obsoletus) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. The California clapper rail was listed as endangered under the Endangered Species Preservation Act in 1970, so was not subject to the current listing processes and, therefore, did not include an analysis of threats to the California clapper rail. In this 5-year review, we will consider listing of this species as endangered or threatened based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of this species. We will consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed. -

A North American Stem Turaco, and the Complex Biogeographic History of Modern Birds Daniel J
Field and Hsiang BMC Evolutionary Biology (2018) 18:102 https://doi.org/10.1186/s12862-018-1212-3 RESEARCHARTICLE Open Access A North American stem turaco, and the complex biogeographic history of modern birds Daniel J. Field1,2* and Allison Y. Hsiang2,3 Abstract Background: Earth’s lower latitudes boast the majority of extant avian species-level and higher-order diversity, with many deeply diverging clades restricted to vestiges of Gondwana. However, palaeontological analyses reveal that many avian crown clades with restricted extant distributions had stem group relatives in very different parts of the world. Results: Our phylogenetic analyses support the enigmatic fossil bird Foro panarium Olson 1992 from the early Eocene (Wasatchian) of Wyoming as a stem turaco (Neornithes: Pan-Musophagidae), a clade that is presently endemic to sub-Saharan Africa. Our analyses offer the first well-supported evidence for a stem musophagid (and therefore a useful fossil calibration for avian molecular divergence analyses), and reveal surprising new information on the early morphology and biogeography of this clade. Total-clade Musophagidae is identified as a potential participant in dispersal via the recently proposed ‘North American Gateway’ during the Palaeogene, and new biogeographic analyses illustrate the importance of the fossil record in revealing the complex historical biogeography of crown birds across geological timescales. Conclusions: In the Palaeogene, total-clade Musophagidae was distributed well outside the range of crown Musophagidae in the present day. This observation is consistent with similar biogeographic observations for numerous other modern bird clades, illustrating shortcomings of historical biogeographic analyses that do not incorporate information from the avian fossil record. -
Waterfowl in the Prehistory of South Dakota
Proceedings of the South Dakota Academy of Science, Vol. 89 (2010) 165 WATERFOWL IN THE PREHISTORY OF SOUTH DAKOTA David C. Parris1* and Kenneth F. Higgins2 1New Jersey State Museum P.O. Box 530 Trenton, NJ 08625-0530 2Wildlife and Fisheries South Dakota State University Brookings, SD 57007 *[email protected] ABSTRACT The paleontological and archaeological records of waterfowl have provided extensive evidence of a sixty million year prehistory of the Order Anseriformes. The distinctive shapes of the skulls and many of the limb bones have enabled recognition of this group in many paleofaunas of the Cenozoic Era, especially in North America. Abundant and useful, waterfowl have had a long association with human populations as well, especially in South Dakota. We compiled an extensive bibliography and examined a number of actual spec- imens in order to provide this review of waterfowl prehistory, focused on South Dakota. The earliest waterfowl, related to the Anseranatidae (Magpie Geese), are fossils from the earliest Paleocene. They are found in sediments laid down shortly after the extinction event that ended the reign of the dinosaurs. Later fossils attributed to waterfowl have been reported from Eocene sediments in Wyoming and from Oligocene, Miocene, and Pliocene rocks in South Dakota. One bone of a duck was recovered from the Late Pleistocene Lange-Ferguson Site (Shannon County), a mammoth kill attributed to early humans. Archaeological sites of the Missouri Basin dam salvage projects produced wa- terfowl bones, demonstrating that the Arikara and other cultures made use of at least thirteen species of swans, geese, and ducks. -

Avian Evolution, Gondwana Biogeography and the Cretaceous
doi 10.1098/rspb.2000.1368 Avian evolution, Gondwana biogeography and the Cretaceous±Tertiary mass extinction event Joel Cracraft Department of Ornithology, American Museum of Natural History, Central Park West at 79th Street, NewYork, NY 10024, USA ( [email protected]) The fossil record has been used to support the origin and radiation of modern birds (Neornithes) in Laurasia after the Cretaceous^Tertiary mass extinction event, whereas molecular clocks have suggested a Cretaceous origin for most avian orders.These alternative views of neornithine evolution are examined using an independent set of evidence, namely phylogenetic relationships and historical biogeography. Phylogenetic relationships of basal lineages of neornithines, including ratite birds and their allies (Palaeognathae), galliforms and anseriforms (Galloanserae), as well as lineages of the more advanced Neoaves (Gruiformes, Caprimulgiformes, Passeriformes and others) demonstrate pervasive trans- Antarctic distribution patterns.The temporal history of the neornithines can be inferred from fossil taxa and the ages of vicariance events, and along with their biogeographical patterns, leads to the conclusion that neornithines arose in Gondwana prior to the Cretaceous^Tertiary extinction event.
