In 1991, Sabath described “larger avian eggs” from the Upper Cretaceous Barun Goyot and Djadokhta Formations of Mongolia. These were later included in the ootaxon Gobioolithus major. Here we recognize the larger avian eggs of Sabath as a distinct ootaxon, Styloolithus sabathi, oogen. et oosp. nov. These eggs differ from those of Gobioolithus in being larger (70 by 32 mm) and more elongate. Microscopically, the shell bears a third layer (possible external zone) thicker than the mammillary layer and nearly as thick as the second layer (possible squamatic zone); the continuous layer (including layers two and three) to mammillary layer thickness ratio is 3.1:1. Within the clutch, the tightly spaced eggs stand with their long axes steeply inclined. Adult remains are associated with two clutches, suggesting an incubation mode similar to that of troodontid maniraptorans, where adults sat atop largely buried eggs. S. sabathi provides evidence that relative egg size in Mesozoic non-ornithuromorph birds had increased markedly from the non-avian theropod condition in oviraptorids and troodontids, but had not yet reached the modern egg-adult proportions of Neornithes. Sediment-bound upright eggs appear common to Enantiornithes and more basal avians, suggesting that like non-avian theropods, these birds lacked chalazae, the chords of albumen allowing egg rotation in modern birds. Absence of this simple structure may have restricted these basal birds to ground nesting in areas with appropriate substrates and not permitted the type of nesting diversity found in Neornithes. Neornithes are the only Mesozoic clade of Dinosauria to nest completely free of sediment; this may have played a crucial role in their surviving the K-Pg mass extinction event.

Calamicoptes anatidus sp. nov., a new species of rarely found parasitic mites of the family Laminosioptidae (Acari: Astigmata) is described from quill walls of wing covert feathers of Aythya marila Linnaeus (Anseriformes: Anatidae) captured in Poland. This is the first record of the family Laminosioptidae on birds of the order Anseriformes and the first record of this mite family in the fauna of Poland. Females of the new species are most similar to those of C. arenariae Lombert, Gaud et Lukoschus, 1984 and differ from them by the presence of the pygidial shield, which covers dorsal and ventro-lateral parts of the opisthosoma, and by having setae c2 and d2 short and subequal in length, and setae se and cp not reaching the metapodonotal shield.

The paper contains a review of quill mites of the subfamily Picobiinae (Acari: Prostigmata: Syringophilidae) associated with woodpeckers (Aves: Piciformes: Picidae). Three new species are described: Picobia mentalis Skoracki et Unsoeld sp. nov. from Picus mentalis Temminck, Neopicobia ea Skoracki et Unsoeld sp. nov. from Celeus flavus (St. Mueller) (type host), C. elegans (St. Mueller), C. torquatus (Boddaert), and Neopicobia freya Skoracki et Unsoeld sp. nov. from Dryocopus galeatus (Temminck) (type host) and Piculus rubiginosus (Swainson). Additionally, six new host species for Picobia heeri Haller, 1878 and 12 new host species for Picobia dryobatis (Fritsch, 1956) are reported. A complete list of the picobiines parasitising birds of the family Picidae is presented in the tabular form.

Fossil avian and reptilian eggs and eggshells, from the Cretaceous of Mongolia and USSR (Kazakhstan, Zaisan basin) as well as samples of dinosaurian and the Eocene avian eggshells from USA, China, France and Argentina were studied. Methodological, terminological and biomineralization aspects of eggshell structure are discussed. Considered are different classifications of eggshell according to the structural levels of eggshell matter organization (texture, general histostructure, superficial morphology). Basic types, morphotypes, types of pore system and types of surface ornamentation are the main structural categories employed in the systematic description of fossil material. About 18 groups of fossil eggshells referred to turtles, geckoes, crocodiles, and to 14 “families” or dinosaur and bird oological remains are described. Their composition, occurence, paleobiology and systematics are shortly presented.

Praca zawiera przegląd budowy skorup jaj gadzich i ptasich oraz propozycją ujednoliconej terminologii oologicznej (fig. 1—8, tab. 1—2). Zbadany materiał obejmuje szczątki kredowych i kenozoicznych jaj gadzich i ptasich z Mongolii, Chin, Azji Środkowej, Francji, USA i Argentyny (pl. 21—39). Autor podaje kryteria klasyfikacji jaj na podstawie skorupy. Wyróżnia kilka poziomów organizacji strukturalnej skorup jaj: teksturę (ultrastrukturalne postaci biomineralizacji), histostrukturę ogólną i ogólną morfologię. Omawia i nazywa typy systemu porów oddechowych i ornamentacji zewnętrznej powierzchni skorupy. Na tej podstawie wyróżnia zasadnicze typy i morfotypy, oparte przede wszystkim na kryteriach ultra- i mikrostrukturalnych, jako najbardziej stabilnych i użytecznych diagnostycznie u grup współczesnych. Parataksonomiczny podział jaj kopalnych obejmuje 14 „rodzin” jaj dinozaurów i 18 grup jaj przypisanych krokodylom, żółwiom i gekkonom. Formalne opisy zawierają obok omówienia swoistych cech budowy skorup zaliczonych do poszczególnych grup także dane o ich występowaniu, spostrzeżenia paleobiologiczne i próbę powiązania parataksonów z grupami naturalnymi organizmów rodzicielskich.

The Solnhofen (Sixth) specimen of Archaeopteryx is assigned to Wellnhoferia grandis gen. et sp. n. on the basis of qualitative, size-independent autapomorphies. Wellnhoferia differs from Archaeopteryx in a short tail with the estimated number of 16-17 caudals; a nearly symmetric pattern of pedal rays II-IV with metatarsals II and IV of equal length and digit IV substantially shorter than in Archaeopteryx; and the number of four (instead of five) phalanges of pedal digit IV, which most probably results from a phylogenetic reduction rather than individual variation. A combination of large size and details of the pelvic limb suggests a locomotor specialization different from that of Archaeopteryx.

Solnhofeński, czyli szósty okaz praptaków przeniesiony zostaje z Archaeopteryx lithographica von Meyer, 1861 do Wellnhoferia grandis gen. et sp. n. na podstawie autapomorfii niezależnych od wielkości ciała, w tym cech jakościowych, merystycznych i proporcji. Okaz ten różni się od okazów Archaeopteryx krótszym ogonem o szacunkowej liczbie kręgów 16-17, bardziej symetryczną budową stopy z kośćmi sródstopia II i IV jednakowej długości i palcem IV zbliżonym długością do palca II, a więc znacznie krótszym niż u Archaeopteryx, i składającym się z 4 zamiast 5 paliczków. Taka budowa stopy przy stosunkowo dużych rozmiarach ciała sugeruje również nieco inną niż u Archaeopteryx, prawdopodobnie bardziej kursorialną, specjalizację lokomototyczną.

Scapular orientation in theropods and basal birds, and the origin of flapping flight

Basal birds such as Archaeopteryx and Confuciusornis are typically portrayed as flapping fliers. However, here I show that shoulder joint orientation in these animals prevented elevation of the humerus above the dorsum, thereby preventing use of the recovery stroke, an important part of flapping flight. In members of the clade Ornithothoraces, which includes extant birds and the extinct avian clade Enantiornithes, the shoulder joint is reoriented to permit elevation of the humerus above the dorsum, permitting flapping flight. Although basal birds may have glided, flapping flight began significantly later in avian evolution than has been thought.
