Description:Dactyloidites is horizontal burrow structure that has a rosetted appearance in plan view; it also can show remanents of a central vertical shaft. Dactyloidites is interpreted as a cumulative deposit-feeding burrow produced by a worm-like animal. The trace began originally as a J-shaped burrow where the animal then probed repeatedly into the sediment in a fan-like pattern.
