Presbyornis - примитивный представитель ствола гусеобразных птиц.

Морфология плечевой кости энанциорнисовых птиц предполагает, что она у них находилась в протрагированном положении по сравнению с таковым у современных птиц. При таком положении плеча дистальное перекручивание способствует выносу предплечья и кисти в субгоризонтальную плоскость.

A new heron species, Ardea sytchevskayae sp. nov., from the Middle Miocene Sharga locality is described. The new species is represented by an almost complete coracoid and a few partial coracoids, partial scapula, and caprometacarpus. A. sytchevskayae was a relatively large heron, of the same size...

Кладограммы обычно включают большое число эволюционных реверсий, параллелизмов и конвер генций, объединяемых под общим понятием гомоплазии. В последние годы стало ясно, что моле кулярные признаки, выглядящие как гомоплазии, на самом деле могут представлять собой истин ные гомологии. Процессы...

A partial synsacrum of a primitive bird from the Zenge Kurgan 3 locality in the Kyzyl Kum Desert (Uzbekistan) is described. The vertebrate fauna from this locality is similar to that of the Bissekty Formation of the Dzharakuduk locality (Central Kyzyl Kum, Uzbekistan); however, this synsacrum...

Medium sized diving ducks from the Middle Miocene of the Sharga locality (western Mongolia) are described. Sharganetta mongolica gen. et sp. nov. and Nogusunna conflictoides gen. et sp. nov. are evolutionary more advanced than the thoroughly studied Early Miocene genus Mionetta, but more...

Получен таксономический состав птиц из средне- миоценового местонахождения Шарга (самого богатого по числу таксонов неогенового местонахождения Азии). Кроме того, изучены новые материалы по неогеновым местонахождениям Хиргис-Нур 2, Чоно-Хариах 1 и 2, Шамар и Береговая. В результате данной...

In recent decades numerous findings, mostly from the Early Cretaceous of China, have changed traditional conceptions about the diversity and evolution of the most ancient Aves. Findings of Mesozoic birds in Russia are extremely rare. Here we describe a new bird from the Lower Cretaceous...

Large phasianids from four Miocene and Pliocene localities of Mongolia are reviewed. Lophogal lus naranbulakensis gen. et sp. nov. from the Middle Miocene of the Naran Bulak locality is described. It resembles extant Gallus, Lophura, and partially Pavo. The fossil pheasant Syrmaticus kozlovae...

The Ostantsevaya Cave (Sakhalin Island, Russian Far East) yielded rich and diverse vertebrate fauna of Late Glacial through Holocene time. The bone assemblage is dominated by remains of brown bear and hare, reindeer and snow sheep. The fauna for the first time documented the presence on Sakhalin...

Phylogenetic analysis based on osteological characters of some Neogene and Recent phasianids is performed. Phylogenetic tree shows close relationships of Plioperdix with Ammoperdix and Tologuica with Excalfactoria. Chauvireria is at the base of the clade (Alectoris + (Coturnix + (Excalfactoria +...

The phasianid genera Perdix, Plioperdix, and Bantamyx from the Neogene of Mongolia and Transbaikalia are reviewed. Based on published data and new material, the diagnoses of Late Pliocene Perdix margaritae Kurochkin and Plioperdix ponticus (Tugarinov) and Late Miocene Bantamyx georgicus Kurochkin...

Representatives of the avian taxon Zygodactylidae are among the most abundant small arboreal birds in the early Palaeogene of the Northern Hemisphere. Still, however, the osteology of these birds, which have recently been shown to be the sister taxon of the Passeriformes, is only incompletely...

A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix....

Recent mousebirds are the smallest of the living neognathous bird orders – just two genera comprising six species. Understanding the evolutionary dynamics of this avian lineage is important because these birds occupy a critical position within Neoaves and can be used as a model for patterns of...

Two new fossil psittaciform birds from the Lower Eocene 'Mo Clay' (Fur Formation) of Denmark (c. 54 Ma) are described. An unnamed specimen is assigned to the extinct avian family of stem-group parrots, Pseudasturidae (genus and species incertae sedis), while a second (Mopsitta tanta...

Djuktai cave is a Paleolithic site located in the south-eastern part of Yakutia. Bird remains originate from the late Pleistocene (12 000–14 000 BP) and late Holocene (about 740 BP) deposits. Anseriform birds are represented by 13 species: Anser sp. nov., Anas platyrhynchos, A. crecca, A....

Avian remains from the Late Palaeolithic Djuktai Cave (15000 – 740 years B.P.) are represented by more than 700 bird bones. We identified 65 species from 10 modern orders. The most abundant are remains of the Willow Grouse (Lagopus lagopus), and Ptarmigan (L. mutus). The remains of Ducks...

Описаны остатки птиц из двух голоценовых местонахождений Белоруссии.

The foot structure of piciform and coraciiform birds is examined in detail. Certain similarity in foot structure between woodpeckers and woodhoopoes is shown and provides the basis for the model of the evolutionary formation of the zygodactyl foot. It is shown that African mousebirds and the...

Миология и остеология дятлов хорошо изучены, однако практически ничего не известно о различи- ях между видами в строении задней конечности. Для обнаружения этих различий и их функциональ- ной интерпретации изучена мускулатура ноги Jynx torquilla, Colaptes auratus, Dryocopus martius, Picoides...

Из верхнеплейстоценовых и голоценовых отложений Дюктайской пещеры (Восточная Сибирь) исследованы остатки птиц, принадлежащие к 64 совре- менным и двум вымершим видам. Приводятся данные по распределению отде- льных таксономических групп по горизонтам, а также по размерам ископае- мых белых...

Пособие посвящено механизмам дыхания и особенностям кровообращения у представителей разных классов хордовых животных. Подробно рассмотрены принципы противоточной системы, различные механизмы дыхания. Дается краткое описание строения кровеносной и дыхательной систем. Пособие может быть...
