Fig 2
A. The shallow box core being extracted at Revdanda tidal flat. B & C. Field photographs of polychaete burrows associated with pellet mounds. The white arrows in C indicate pellet mounds. Innumerable pellets lie dispersed in the background on the surface of the mudflats. D. Wavy, sinuous and branched burrows of uniform width. Inset: pellet cluster. E. SEM photograph of a pellet aggregate. F & G. SEM images showing surficial striae on pellets. The pellet in F shows an attachment scar in negative relief. H. The undisturbed surface of the box core covered with randomly oriented pellets. Numerous cross-sections of pellets directed towards the reader show dark, homogenous internal structure of pellets. I. One of the several strings of fecal pellets connecting two pellet mounds. J. Lateral surface of box core showing stacked laminae of pellets.
