• The trace fossil Rosselia socialis Dahmer, 1937 is a thickly mud-lined and spindle-shaped tube oriented vertically or obliquely to the bedding plane. It is known to record detailed information on the paleoenvironment. Although it has been reported from Lower Cambrian to upper Pleistocene deposits, no Holocene specimens have previously been found. Well preserved specimens of R. socialis are herein reported from the Holocene shallow marine deposits at Shima, Tako Town, Chiba Prefecture, central Japan, co-occurring with some prehistoric earthenware vessels that were made from 9950 to 2950 yrs. B.P. This is the vouneest record of R. socialis.
