Prehistoric fishhooks have previously been described in northern Europe as being common since the Mesolithic. Here we present a Final Palaeolithic ivory fishhook from the site Wustermark 22 (north-eastern Germany), the raw material of which is about 19,000 years old. Five further fishhooks were discovered in situ at the same site one of which has a calibrated radiocarbon age of about 12,300 years. The tool industries of flint artefacts and bone/antler tools are associated with descendants of the Federmesser-culture and the palynological context indicates a Younger Dryas environment. Wustermark 22 represents the largest collection of Palaeolithic fishhooks so far found at a single European site. A comparison with other sites in Europe, containing Palaeolithic fishhooks suggests that the appearance and development of fishhooks may be associated with a general change in resource availability during the Greenland Interstadial 1 (Bølling/Allerød warming), which is also connected with a change from late Upper Palaeolithic to Final Palaeolithic industries in Northern Central Europe. We conclude that Mesolithic fishhook tradition has its roots in the Final Palaeolithic. 相似文献

ABSTRACT This paper expands the literature on agglomeration economies in three ways. It disentangles amenity and productivity effects of agglomeration; it decomposes aggregate scale effects into agglomeration factors of interest to policy makers; and it estimates own effects and spillovers to neighbors. It proposes a spatial simultaneous equations model in a spatial equilibrium framework with three agents—workers, consumers, and producers of traded‐goods and housing. Results for Ohio counties estimate economies resulting from population size, agglomeration causes, and public service quality and cost on each of the three agents in own and neighboring counties. 相似文献
