  abstract = {{W}e measured the 14{C} age of pre-bomb suspension-feeding bivalves of known age from coastal {W}est {A}frica across a latitudinal transect extending from 33 circle {N} to 15 circle {S}. {T}he specimens are from collections belonging to the {M}useum {N}ational d'{H}istoire {N}aturelle ({P}aris, {F}rance). {T}hey were carefully chosen to ensure that the specimens were collected alive or that they died not long before collection. {F}rom the 14{C} dating of the known-age bivalves, we calculated the marine reservoir age (as {D}elta {R} and {R} values) for each specimen. {D}elta {R} values were calculated relative to the {M}arine20 calibration curve, and the {R} values were calculated relative to {I}ntcal20 or {SH}cal20 calibration curves. {E}xcept for five outliers, the {D}elta {R} and {R} values were generally homogenous with weighted mean values of -72 +/- 42 14{C} years (1 {SD}, n=24) and 406 +/- 56 14{C} years (1 {SD}, n=24) respectively. {T}hese values are typical of low-latitude marine reservoir age values. {F}ive suspension-feeding species living in five different ecological habitats were studied. {F}or localities where several species were available, the results yielded similar results whatever the species considered, suggesting that, in these locations, the habitat has only a limited impact on marine reservoir age reconstruction. {W}e show that our measured marine reservoir ages follow the declining trend of the global marine reservoir age starting ca. 1900 {CE}, suggesting that the marine reservoir age of coastal {W}est {A}frica is driven, at least to the first order, by the atmospheric {CO}2 14{C} ageing due to fossil fuel burning rather than by local effects. {E}ach outlier was discussed. {L}ocal upwelling conditions or sub-fossil specimens may explain the older 14{C} age and thus the larger marine reservoir ages for these samples. {B}ucardium ringens might not be the best choice for marine reservoir age reconstructions.},
