The excavation in the 1890s of a skeleton of the warm‐water marine mammal Dugong dugon, associated with Aboriginal artefacts, from a Botany Bay salt marsh, marked the beginning of speculation about climate and sea level change in Australia over the period of human occupation. The dugong bones have recently been dated, giving a conventional 14C age of 5520±70 years BP, which is consistent with three older 14C dates for a layer of buried trees that underlies much of the north Botany sediments. The carefully drawn cross‐sections of depositional strata produced by the original discoverers allow further interpretation of the pattern of Holocene sea‐level fluctuations in the Sydney region. Layers of estuarine sediment, such as the one containing the dugong skeleton, are inter‐bedded with peat layers containing in situ roots and stumps, suggesting that the site alternated between sub‐aerial exposure and submergence throughout the Holocene. The presence of the dugong is suggestive of warmer conditions, and its inland location indicates a more extensive Botany Bay in the recent past. This is in agreement with other work from southern New South Wales describing both warm‐water marine species and higher sea levels several thousand years ago.

Introduction     
In November 2004, France carried out one of the biggest evacuation operations of its expatriates since the Algerian War of 1954–1962. Within a couple of days, more than 8000 French citizens were forced to leave Côte d'Ivoire because of violent anti-French protests by the supporters of the Ivorian regime. This article examines the dispute between French repatriates from Côte d'Ivoire and the French government by analysing the arguments put forward by both sides in legal texts and semi-structured interviews conducted in France and Côte d'Ivoire. It is argued that the dispute cannot be explained satisfactorily as a mere instrumentalisation of the current debates in France about Françafrique. On the contrary, the article shows that Françafrique should be understood primarily as an ideological discourse that organises Franco-African relations and makes them resilient to change.  相似文献
