In the Thar Desert, northwest India, aeolian sand grains were sampled from late Pleistocene dunes and the presence of marine Foraminifera was noted. The frequency of Foraminifera declines in a progressive fashion with distance from the sea, but they are found at least up to 800 km from the nearest point downwind on the coast. This indicates that Foraminifera have been susceptible to long distance transport by the wind, that the coast has been an important source area for the sands of the Thar Desert, and that the presence of Foraminifera in aeolian sediments does not necessarily imply former close proximity to the sea.
