Daily growth increments on fish otoliths as seasonality indicators on archaeological sites: The Tilapia from late palaeolithic Makhadma in Egypt

Daily growth increments in fish otoliths have been demonstrated for the first time on Quaternary sagittae from a late palaeolithic site in Egypt and they have allowed us to establish the season of fishing. Transverse sections of tilapia sagittae studied under light-microscope demonstrate that recrystallization during diagenesis renders the majority of the margins unreadable. The well-preserved otoliths, however, all have widely spaced outer growth lines, indicating that the fish died during a period of fast growth which coincides with the flood season. Moreover, counting the daily increments showed that late palaeolithic man captured the animals on the floodplain of the Nile after the maximum of the flood, when residual pools were present.     

Seasonality only works in certain parts of the year: the reconstruction of fishing seasons through otolith analysis

Seasonality estimations using incremental data usually suffer from small sample sizes and from the lack of comparison with sufficiently large modern samples. The present contribution reports on incremental studies carried out on large assemblages of plaice (Pleuronectes platessa) and haddock (Melanogrammus aeglefinus) from a late medieval fishing village (Raversijde, Belgium) on the North Sea coast. In an attempt to refine previous seasonality estimates made for this site, and to expand conclusions concerning general methodology, extensive monthly samples of modern otoliths of these species, caught within the North Sea, have also been investigated. The modern material shows that the timing of the seasonal changes in the edge type (hyaline or opaque) of the otoliths is extremely variable and that it is dependent on the fishing ground, the year considered, and the age of the fish. It also appears that the increase of the marginal increment thickness is highly variable, to such an extent that the thickness of the last increment of a single otolith is mostly useless for seasonality estimation. Where large archaeological otolith assemblages can be studied, preferably from single depositional events, seasonality determination becomes possible on the condition, however, that the archaeological assemblage corresponds to fish that were captured during their period of fast growth. The growth ring study on the otoliths from Raversijde shows that plaice fishing took place in spring and that it was preceded by a haddock fishing season, probably in late winter/early spring.

Estimation of Age,Growth and Fishing Season of a Palaeolithic Population of Grayling (Thymallus thymallus) Using Scale Analysis

The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus ¸ has the most easily recognizable scales and is a commonly recovered species from Palaeolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n  = 22), Switzerland (n  = 16), Finland (n  = 20) and Sweden (n  = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The results showed that the archaeological population of grayling is closer to the present Finnish population. Furthermore, the comparison of seasonal growth patterns between current and archaeological European populations demonstrated that graylings were normally captured during the spring at Le Taillis des Coteaux Magdalenian site. This type of approach can be used to understand environmental conditions at a low spatial scale and also to help identify fishing seasons during archaeological periods.

The Role of The Gentleman's Magazine in the Dissemination of Knowledge About Electric Fish in the Eighteenth Century

Although torpedoes and Malopterurus, a Nile catfish, had been described and even used medically in antiquity, their discharges were poorly understood before the second half of the eighteenth century. It was then that their actions, along with those of certain South American “eels,” became firmly associated with electricity. The realization that an animal could produce electricity marked a turning point in the history of neurophysiology, which had long described nerve actions with recourse to animal spirits. By examining The Gentleman's Magazine during the period when electric fish were becoming electrical, one can begin to appreciate how new discoveries about these unusual creatures captured the imagination of scientists and were filtered down to the literate public.     

Fish communities and populations during the post-Saladoid period (AD 600/800–1500), Anguilla,Lesser Antilles

Analysis of vertebrate remains from two archaeological sites indicates human exploitation did not adversely impact fish populations and fish communities during the post-Saladoid period (AD 600/800–1500) on Anguilla, northern Lesser Antilles. Barnes Bay (AL-14-BB) and Sandy Ground (AL-03-SG) are contemporaneous, large village sites located within 10 km of one another in similar terrestrial and adjacent marine environments. Despite substantial human population growth and increasing social complexity by AD 1000, residents at these sites exploited the same marine fishes and captured similar relative frequencies of fish families throughout the occupational sequence. No evidence of overfishing is found, either as a decline in the mean size of members of three fish families or in the ranges of size of these families through time. Evidence of a greater use of some members of a fourth family is found at Sandy Ground during the later post-Saladoid. It is likely that economic or social factors, rather than environmental change, contributed to this increase. By identifying specific locations where human over-exploitation did or did not impact fisheries, we may begin to distinguish patterns and characteristics which led to unsustainable fishing in the past at other sites, or in other circumstances.     

Insights into early Holocene hunter-gatherer mobility on the Peruvian Southern Coast from mollusk gathering seasonality

Quebrada de los Burros (QLB) is an early Archaic coastal archaeological site in southern Peru (∼18.1°S) and the most extensively studied in the area for this period. It was occupied from 10 to 6.5 ka by fishermen also practicing hunting and mollusk gathering. Shell growth lines in 116 individuals of the surf clam Mesodesma donacium were studied to determine the month of their death (±2 months). Our results show that, for the whole occupation period, mollusk gathering was a seasonal activity mainly practiced during austral spring and summer. A change occurred between the early and the middle Holocene: the mollusk gathering season in the middle Holocene occurred ∼3 months earlier in the year than in the older levels. This behavior change could have a cultural origin, rather than dictated by the environment for it is associated with changes in the lithic industry. QLB occupants also hunted herbivores in the nearby lomas ecosystems. These plant communities only grow during the fog season from June to December, suggesting that the site was occupied during this season. A comparison of the span of the mollusk gathering season and the lomas season suggests that, at least during the early Holocene, QLB was occupied all the year round. A permanent freshwater source and the proximity of the sea, the lomas, and raw lithic materials, provided ideal conditions for a permanent occupation. This result reveals a strategy based on a seasonal alternation between marine and terrestrial resources exploitation.     

A 2500‐year record of marine resource use on Ulong Island,Republic of Palau

The paper reports fish bone and shellfish assemblages from Ulong Island in the Rock Islands of Palau, western Micronesia dating from ∼3100 to 500 BP . Use of marine resources in early prehistory appears to have been highly localised with increasing capture of outer‐reef/pelagic taxa including shark and tuna after 1000 BP . Local stocks of large Tridacnids were depleted during initial human use of Ulong Island, and there is a size decrease in Scarus sp. remains consistent with pressure on the inshore fishery, especially after establishment of permanent stonework villages in late prehistory. Comparison of archaeological assemblages of fish bone from other Rock Islands dated to after 2000 BP indicate that the captured fish species and major capture methods differ between sites and likely reflect local marine environments at each location.

Fishing in Denmark during the Ertebølle periodxs

Fishing in Denmark during the Ertebølle period is discussed on the basis of almost 100000 identified fishbones from 14 coastal and two inland settlements. Forty-one fish species were identified from coastal materials, 15 from inland ones. The frequency distribution of total body length of the numerically most important fish species was estimated from bone measurements, using logarithmic regression equations. Otoliths were analysed in order to provide an estimate of season of catch. The main conclusion of the study is that fishing was predominantly conducted by means of stationary fish traps with which uncritical samples of the local fish faunas were taken. Regional differences in the spectrum of species and their relative frequencies are shown to exist. Examples of connections between the coast and inland are given.     

Middle Holocene fishing strategies in East Africa: zooarchaeological analysis of Pundo,a Kansyore shell midden in northern Nyanza (Kenya)

A zooarchaeological and taphonomic analysis is presented for the faunal remains from the Pundo shell midden in northern Nyanza province (Kenya), which contains Kansyore ceramics and dates to ca. 8000–7600 cal. BP. The faunal assemblage is overwhelmingly dominated by fish and molluscs, of which only the fish data are presented in detail. Taxonomic identifications suggest a diachronic change in relative species abundance, with cichlids becoming increasingly dominant, eventually comprising nearly 80% of the fish assemblage. The Pundo faunal data are compared with those from a number of other Kansyore sites. Pundo confirms that early Kansyore sites are purely forager sites, with domestic caprines only appearing at late Kansyore sites (post‐dating ca. 4400 cal. BP). Comparing ethological data for fish taxa found at Pundo and other lakeshore shell middens with those for fish taxa found at larger riverside sites, a seasonal round is suggested, in which short‐term fishing camps such as Pundo may have been occupied in the dry season, while riverside sites were probably occupied during the rainy season.

Reconstructing age distribution,season of capture and growth rate of fish from archaeological sites based on otoliths and vertebrae

The growth increments of otoliths and vertebrae of plaice (Pleuronectes platessa) derived from a 15th century single depositional event at Raversijde (Belgium) are analysed with the aim of reconstructing (a) the age distribution of the population, (b) the season of capture, and (c) the growth rate. Otoliths and vertebrae give slightly different age distributions but it is possible to arrive at similar seasonality estimations in both structures when information from the literature and our own data from monthly captures of plaice from the North Sea are taken into account. These modern data show that the timing of annulus formation in otoliths and vertebrae is more or less similar. Back‐calculations on vertebrae and otoliths yield similar growth curves. The age distribution, the edge condition of both vertebrae and otoliths, and the growth rate obtained on the material from Raversijde all show that the plaice from the studied assemblage were captured during spring in the southern part of the North Sea. Vertebrae are commonly preserved in archaeological sites whereas otoliths rarely survive. Although they are more difficult to read than otoliths, vertebrae of plaice can be used for growth increment analyses, and the growth rates obtained from vertebrae from archaeological sites can, therefore, be compared in the future to growth data from modern otoliths studied in sea fisheries research. Archaeozoological material predating industrialized fishing since the 19th century can hence serve as a reference in the study of the compensatory response of commercially important species to heavy exploitation.

The pectoral fin spines of European catfish Siluris glanis; cultural artifacts or food remains?

The urban archaeological site of Nicopolis ad Istrum in north central Bulgaria, which has multiple periods of use and abandonment, has produced a large and varied ichthyofauna. A number of bones of the European catfish Siluris glanis have been identified and have been interpreted as both food remains and bone artifacts. It was found that a percentage bias in the distribution of S. glanis bones from the Roman period of occupation called for further analysis. The investigation attempts to identify the reason or reasons for the apparent overrepresentation of the pectoral fin spines of this species. Taphonomic factors are considered along with butchery and an actualistic study of butchery on modern S. glanis material. Studies from north Africa are used to illustrate the possible function of the spines. The conclusions drawn are that a high proportion of the pectoral fin spines were brought into the site, possibly as personal artifacts. Their use is open to debate; no clear functional use can be determined from the archaeological material, although it cannot be ruled out that they were used for medicinal purposes or as charms.     

The radiocarbon reservoir effect: new evidence from the cemeteries of the middle and lower Dnieper basin,Ukraine

This paper presents preliminary results of new radiocarbon dating of human, faunal and fish skeletal remains from a number of the cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results appear to demonstrate the presence of a radiocarbon reservoir effect during the Neolithic–Eneolithic periods, the first time that this has been identified in this region. The data indicate that the radiocarbon reservoir effect is currently only evident during these periods, and not in the earlier Epipalaeolithic–Mesolithic periods, prompting the suggestion that the radiocarbon reservoir effect is associated with elevated fish consumption from the Neolithic period onwards.     

A pre-Columbian fisheries baseline from the Caribbean

A pre-Columbian (ca. AD 500–1500) fishery baseline is established for Anguilla, British West Indies from analyses of the remains of captured fishes from five archaeological sites. The zooarchaeological fishery baseline shows pre-Columbian communities captured diverse fishes, many of which are vulnerable to overexploitation. Composition of the captured fish community varies by site underscoring the potential importance of including samples from sites located adjacent to different marine habitats. Analyses of abundance–biomass relationships, community trophic structure, fish size and taxonomic composition indicate the Anguillian pre-Columbian fishery and coral reef ecosystem was healthy and sustainable. By providing a thorough baseline of Amerindian use of fishes on Anguilla, we provide a foundation that aids researchers asking questions about long-term change in Caribbean coral reef fisheries.     

Developing baseline data to understand environmental change: a geochemical study of archaeological otoliths from the Coorong,South Australia

Otoliths are calcium carbonate structures found in the inner ear of teleost fish. While they are routinely studied by marine scientists, analyses of otoliths recovered from archaeological sites in Australia and the Pacific have generally been restricted to identification of species and sometimes the fish age. Otoliths can also provide information on the season of catch, and, through trace element analysis, allow the reconstruction of environmental conditions experienced by fish. In this study, we use otoliths from mid- to late Holocene aged archaeological shell middens at the Coorong (South Australia) to examine species present, season of catch, age of fish and environmental conditions experienced by fish. Results demonstrate that the majority of the fish (identified as Argyrosomus japonicus and Acanthopagrus butcheri) were caught in freshwater environments during the warm season, and had grown to an age and size indicative of their having reached sexual maturity. This study provides data indicating fluctuating levels of salinity in the estuary, which are significantly lower than the hypersaline conditions experienced today. Ultimately, this project highlights the usefulness of conducting more detailed investigations of otoliths, including geochemical analyses, to address a wide range of research questions in archaeology and palaeoenvironmental research.     

Fishery in prehistoric and medieval Tallinn,Estonia

During archaeological excavations in central Tallinn, Estonia, many fish bones were collected among other archaeological finds. As these were salvage excavations conducted under limited time and cost restraints, only a very small part of the removed soil could be examined for fish bones. In such hasty conditions, the only option was to take soil samples from selected areas and carry out water sieving in the laboratory. This procedure resulted in the recovery of a variety of fish remains. Also, a previous conclusion that only large fish were captured is re-evaluated. This paper focuses on two recently excavated medieval sites in Tallinn: Tartu Road 1 and Vabaduse Square. In Vabaduse Square, a Late Neolithic settlement was also discovered under the medieval layers. The analysis of the three different assemblages of fish bones from the two sites, which were collected by somewhat different methods, contributes to our knowledge on fishing and fish consumption in Tallinn's past.     

Seasonality and age structure in an archaeological assemblage of Sika deer (Cervus nippon)

Sika deer (Cervus nippon) was one of the major terrestrial mammals hunted in Japan throughout the Jomon period, which extends from the end of the Palaeolithic until the arrival of rice agriculture in the first millennium bc . Mandibular analysis of hunted deer is believed to be more useful in determining the season of death than antlers in archaeological contexts. This paper aims to present a new method of estimating an occupational season of a Jomon site by using sika deer mandibles. This method consists of two stages. First, two measurements on a mandible should be taken. If the distribution shows any gaps among young juveniles, this strongly suggests that the sika was hunted in a specific season. Second, tooth eruption and attrition stage should be observed; this may suggest the season in which hunting took place. This method was utilized to analyse sika deer remains from Awashimadai in eastern Kanto. The result of the analysis shows that deer were hunted only from spring to summer at Awashimadai. Putting these results together with the estimate of seasonality deduced from other species strongly suggests that the site was occupied only from April to July. This paper also examines how the tooth attrition stages of sika deer progress. The preliminary comparison with red deer (Cervus elaphus) in England suggests that molar wear progresses more quickly in sika than in red deer. Copyright © 1999 John Wiley & Sons, Ltd.     

A Wax Effigy Pierced by Three Bones: The Pharaonic Origins of a Late-Antique Cursing Ritual?

Papyrus fragments from a late-antique Greek magical handbook preserve a unique recipe that directs us to make a wax “voodoo doll” and pierce it with three bones – “the left one, the right one and the one from the back” – “of an eisphatēs”, a previously unknown Greek word that has been emended to mean “sacrificial victim” (sphaktēs) or “dove” (phattēs). Emendation is not warranted, however, because the word is probably a local and previously unknown Egyptian term for the Nile catfish, which has three distinctive nail-like spines – the right and left pectoral and the dorsal – that match those of the eisphatēs. The bone of this fish is, moreover, used in a native Egyptian cursing ritual of Pharaonic date also involving a wax “voodoo doll”, that is inscribed with the bone, rather than pierced by it.     

Seasonality of human site occupation based on stable oxygen isotope ratios of cod otoliths

Oxygen isotope ratios (δ¹⁸O) were measured in micromilled samples of cod otoliths recovered from two Stone Age sites, one from Skoklefald, southeastern Norway and five from Skipshelleren, southwestern Norway. Discrete samples of otolith material were milled from the edge of the otolith towards the centre, each sample representing 3–4 weeks of growth. The δ¹⁸O values showed seasonal signals, covering a period 1–2 years prior to the time of capture. Isotope ratios at the edge of the otoliths, which is the material deposited at the time of fish capture, corresponded to the coldest seasonal water temperatures, in late winter or early spring. These data provide independent evidence for the season of use of the Skoklefald and Skipshelleren sites.     

Asteropygine trilobites from the Late Devonian of the Kerman region,Iran

The discovery of two new Frasnian species of the subfamily Asteropyginae, Bradocryphaeus kermanensis and Radiopyge hamedii, in the Haruz section north of Kerman, east-central Iran, demonstrates for the first time the presence of North Gondwanan trilobites in this region. The two new species provide a link between faunas from Afghanistan to the east and the Alborz Mountains in north Iran. The recognition of R. hamedii confirms the validity of Radiopyge Farsan, hitherto known only from Afghanistan, as well as the presence in some Frasnian Asteropyginae of six pairs of lateral pygidial spines.     

High-resolution sclerochronological analysis of the bivalve mollusk Saxidomus gigantea from Alaska and British Columbia: techniques for revealing environmental archives and archaeological seasonality

The butter clam, Saxidomus gigantea, is one of the most commonly recovered bivalves from archaeological shell middens on the Pacific Coast of North America. This study presents the results of the sclerochronology of modern specimens of S. gigantea, collected monthly from Pender Island (British Columbia), and additional modern specimens from the Dundas Islands (BC) and Mink and Little Takli Islands (Alaska). The methods presented can be used as a template to interpret local environmental conditions and increase the precision of seasonality estimates in shellfish using sclerochronology and oxygen isotope analysis. This method can also identify, with a high degree of accuracy, the date of shell collection to the nearest fortnightly cycle, the time of day the shell was collected and the approximate tidal elevation (i.e., approx. water depth and distance from the shoreline) from which the shell was collected.Life-history traits of S. gigantea were analyzed to understand the timing of growth line formation, the duration of the growing season, the growth rate, and the reliability of annual increments. We also examine the influence of the tidal regime and freshwater mixing in estuarine locations and how these variables can affect both incremental structures and oxygen isotope values. The results of the sclerochronological analysis show that there is a latitudinal trend in shell growth that needs to be considered when using shells for seasonality studies.Oxygen isotope analysis reveals clear annual cycles with the most positive values corresponding to the annual winter growth lines, and the most negative values corresponding to high temperatures during the summer. Intra-annual increment widths demonstrate clear seasonal oscillations with broadest increments in summer and very narrow increments or no growth during the winter months. This study provides new insights into the biology, geochemistry and seasonal growth of S. gigantea, which are crucial for paleoclimate reconstructions and interpreting seasonality patterns of past human collection.
