The potential of bird remains for environmental reconstruction

Until relatively recently, studies of bird remains have been regarded as peripheral to mainstream research on early archaeological and palaeontological sites, rather than a potentially crucial factor in the reconstruction of the past environments in which hominids and other larger mammals were present This paper sets out to define the range of ecological information for a site which can be gained through study of the bird bones, using as an example the bones recovered in the excavations at Gorham's Cave, Gibraltar. © 1997 John Wiley & Sons, Ltd.     

Past human exploitation of birds on the Isle of Man

This paper makes comparisons between various sources—historical, ethnographic and archaeological—that relate to birds on the Isle of Man, in order to give a picture of the former uses of birds by the Manx people. Written references suggest that seabirds in particular were an important source of the essentials of life, and this is reinforced by recent archaeological evidence. The bird bones discussed are from excavations at St Patrick's Island off the west coast and Castle Rushen, Castletown. Manx Shearwaters Puffinus puffinus were present in greater numbers than they are now, and two fragments of the now extinct great auk Pinguinis impennis were identified, confirming the presence of this species on the Isle of Man. The evidence points to over-harvesting of the shearwaters and members of the auk family. © 1997 John Wiley & Sons, Ltd.     

The first fossil avian egg from Brazil

Marsola, J.C.A., Grellet-Tinner, G., Montefeltro, F.C., Sayão, J.M., Hsiou, A.S. & Langer, M.C., 2014. The first fossil avian egg from Brazil. Alcheringa 38, 563–567. ISSN 0311-5518.

In contrast to the rich record of eggs from non-avian dinosaurs, complete eggs attributable to Mesozoic birds are relatively scarce. Nevertheless, several well-preserved specimens have been discovered over the last three decades revealing functional and phylogenetic characters that shed light on the breeding strategies of extinct birds. Here we report the first fossil avian egg from Brazil, which was discovered in Upper Cretaceous strata of São Paulo in the southeastern part of the country. The taxonomic identity and structural features of the biomineralized tissues were determined using a combination of Scanning Electron Microscopy, Wave Dispersion Energy analyses and Computed Tomography. These show that the 125.5-μm-thick shell of the 31.4?×?19.5?mm egg incorporates three structural layers of similar thickness with both prismatic and aprismatic boundaries. Close similarity between the Brazilian bird egg and those of enantiornithines from the Upper Cretaceous Bajo de la Carpa Formation (Río Colorado Subgroup) of Argentina advocates affinity with basal Ornithothoraces. Furthermore, coherency of their depositional contexts might imply a compatible preference for breeding and nesting environments.

Fragmentation of Bird Bones in Food Remains of Imperial Eagles (Aquila heliaca)

Fragmentation of bird bones in pellets and uneaten food remains of imperial eagles (Aquila heliaca) was studied. The degree of fragmentation was higher than that produced by owls and lower than that in gyrfalcons. There were significant differences between pellets and uneaten remains in the survival of bones and their fragmentation. © 1997 by John Wiley & Sons, Ltd. Int. J.

《论语》雌雉节新解

《论语》雌雉节汉代以来无定解。朱熹在《四书集注》中判此节两处有阙文,此说遂成定论。此节与《乡党》篇旨通意连,决无阙文。两千年来先贤大师释不通此节,关键在于离开“雌雉”之“雌”而去释解“时哉时哉”,结果变成离“礼’’释义。只要从“雌”字着眼,以“雌”释“时”,“山梁雌雉,时哉时哉”就与“礼”连接起来。雌雉节是子路惊飞孵卵雌雉,孔子强调此时正是雌雉孵卵之时,责备子路不应违反“不唐不卵”的时令之“礼”。子路打拱认错,雌雉终又惊飞。此解不见于《论语》讲读各家释义。     

Stone Age exploitation of birds on the island of Gotland,Baltic Sea: a taphonomic study of the avifauna on the Neolithic site of Ajvide

We have conducted a detailed taphonomic study of the avifauna of the Pitted Ware culture site of Ajvide on the Island of Gotland in the Baltic Sea, in order to investigate the fowling patterns and the taphonomic history of the bird remains. We have investigated cultural as well as natural modifications on the bird bones, fragmentation and fracture patterns, and performed a systematic surface modification study. No specific area for the deposition of bird remains or specific bird species was identified. All major anatomical parts of birds are present in the assemblage, but there is a dominance of specimens from the wing elements. Traces of cultural modification were observed on the bones, including cut marks, burning, modification (implements, beads, raw material), and gnawing marks. The bone surface modifications and fracture analysis indicate that the majority of the bird bones at Ajvide did not lie on the soil surface for an extended period of time before being deposited in the soil. Dry fractures increase while fresh fractures decrease towards the upper levels of the stratigraphy, indicating more extensive post‐depositional destruction. This may partly be connected to modern agriculture, but also to later use of the settlement area as a burial ground. The Ajvide assemblage contains a variety of birds living in different biotopes. However, bird hunting was mainly focused on sea birds. Auks and ducks are the most common families in the assemblage. We find it likely that the Ajvide hunters conducted organised hunting expeditions to two nearby islands for the hunting of auks, while it was possible to hunt other birds such as ducks closer to the site. The presence of medullary bone and bones from subadult birds indicates a main hunting season in late spring and early summer. However, comparisons with modern migration patterns indicate that hunting may have occurred throughout the year. Of special palaeozoological interest is the find of gannet (Morus bassanus), which apparently in Neolithic times visited the Baltic area more regularly than today.

Redescription of the Miocene penguin Pseudaptenodytes macraei Simpson (Aves: Sphenisciformes) and redefinition of the taxonomic status of ?Pseudaptenodytes minor Simpson

Pseudaptenodytes macraei is redescribed in detail using current avian anatomical terminology. The age of the species is constrained to the late Miocene, and two humeral autapomorphies are identified for the species: a flattened elliptical ventral portion of the fossa tricipitalis and a curved margo cranialis lacking a preaxial angle. Pseudaptenodytes macraei is a distinct taxon based on a diagnostic-type specimen, but it is recommended that the nominal congener Pseudaptenodytes minor be designated a nomen dubium pending the discovery of more complete material.     

First record of Procariama simplex Rovereto, 1914 (Phorusrhacidae,Psilopterinae) in the Cerro Azul Formation (upper Miocene) of La Pampa Province; remarks on its anatomy,palaeogeography and chronological range

Vezzosi, R.I., June 2012. First record of Procariama simplex Rovereto, 1914 (Phorusrhacidae, Psilopterinae) in the Cerro Azul Formation (upper Miocene) of La Pampa Province; remarks on its anatomy, palaeogeography and chronological range. Alcheringa, 157–169. ISSN 0311-5518.

New records of Procariama simplex in central and northwestern Argentina are reported. The fossil material includes mandibular bones, cervical vertebrae and several elements of the fore and hindlimbs. After an exhaustive comparison of anatomical characters and morphometric analysis, the fossil specimens are assigned to the psilopterine Procariama simplex. The specimen from La Pampa Province represents the first record of a psilopterine in this central region of Argentina and derives from upper Miocene sediments of the Cerro Azul Formation. Lithological features and biostratigraphical data allow the host bed to be assigned to the Huayquerian faunal stage (late Miocene). The La Pampa record broadens the geographical distribution of Procariama simplex, which was previously restricted to northwestern Argentina.

Butchering and cooking of birds in the palaeolithic site of Grotta Romanelli (Italy)

Grotta Romanelli is one of the most important sites of the Italian palaeolithic. It contains a lithic industry from the Final Epigravettian, examples of rock and mobiliary art and numerous bone remains, among which were abundant remains of birds. Approximately 32 000 bird bones from over 3650 individuals and 109 species were identified. The most common species were bustards, Otis tetrax and O. tarda, and three species of goose, Anser fabalis, A. albifrons and Branta bernicla. Traces of butchering and burning were evident on numerous bones. The nature and location of the cut marks and burning is described here. The analysis has involved mostly the hind limbs and the shoulder girdle where traces are most numerous. The cut marks reflect a codified sequence of actions of disarticulation and dismemberment. © 1997 John Wiley & Sons, Ltd.
