One example of a bioturbator that may have lived in this area, if it was oxygenated, is aquatic worms similar to this little terrestrial earthworm (Ctenoscolex procerus Ehlers). This worm was probably thrown into this part of the lagoon by a passing storm or dropped by a flying creature as it flew over the lagoon. Once in there it died and was burried, preserving all the detail of its soft body. If this was an oxygenated area aquatic worms or other bioturbators would have crawled around in the subsurface eating all the organic debris that had settled there, thereby destroying detail (modified from Barthel et. al., 1990).
