Abstract
Biogenic mounds made of materials ejected around burrow openings are preserved in miliolite deposits of Saurashtra region of western India. The mounds are associated with scratchings on the bedding planes. Burrows of varying diameters, partially filled with sediments, are inclined to the bedding (max. 28°) and reach a depth of up to 15 cm. The presence of these lebensspuren, attributable to crabs, precludesthe inland miliolites of the Saurashtra Peninsula being considered as arrested dunes. From 234U and corrected 230Th concentrations, the age of the rocks containing the mounds is 54.2±6.2 Kyr B.P. This finding might throw light on the palaeoenvironmental response to Quaternary neotectonism and sea level changes in the Saurashtra Peninsula, India.
