The ichnogenus Protovirgularia McCoy, 1850 is reported from nonmarine strata of the Cretaceous Jinju Formation of the Sacheon area Korea. There, the Jinju Formation is composed mainly of fine-grained sandstone, grey to brownish grey mudstone, and shale which were deposited in a freshwater lacustrine environment. This occurrence represents the fist formal recording of the ichnotaxon from Korea and the first, on a global basis, from a nonmarine depositional environment.
