Many structures that were once interpreted as fossils of plants, sea-grasses, or seaweeds are now treated as ichnofossils produced by ancient marine benthic animals. However, the origin ofArchaeozosterahas still debated owing to a lack of clear and persuasive evidence. At last, we found special specimens thatArchaeozosterais not a fossil of the Zosteracean sea-grass but a trace fossil produced by infaunal benthic animal from the late Cretaceous submarine fan deposits in Japan. Detailed field observations of occurrence, morphological analysis, and X-ray diffraction analysis revealed that previous discussions ofArchaeozosterawere based not only on incomplete specimens but also on biased outcrop observations. On the basis of morphological analysis of new specimens, we demonstrate the first complete overall morphology ofArchaeozosteraand clear evidence thatArchaeozosterais a trace fossil produced by a sedentary endobenthic detritus feeder, which systematically excreted fecal matter deep in sediments. A representative specimen ofArchaeozostera, which has recently found from Eocene deep-sea sediments in Spanish Pyrenees, strongly suggests that it is no longer an endemic trace fossil of the Upper Cretaceous of Japan.
