Imprints are relatively deep (0.5-1.5 mm) and are separated from the median ridge by less than 0.5 mm.

BEHAVIOR(S): Repichnia

POSSIBLE TRACEMAKERS: Isopod crustaceans

GEOLOGIC RANGE: ?Devonian-?Triassic

REMARKS: Description from Brady (1949) and Gaillard (2005). Oniscoidichnus was originally named Isopodichnus Brady 1947 but was changed to Oniscoidichnus; the ichnogenus resembles trackways of modern isopod Oniscus (Brady, 1949).
