Chrono-59 and biostratigraphic12 classification of the crater infill of the Ries and the Steinheim impact structures and the lower and upper seismite horizons. The lower seismite horizon of Ries age5,6 is embedded in OSM deposits that contain faunal elements characteristic for the ELMZ MN 5/6 to MN 6. The lowermost Ries crater lake deposits are dominated by the same faunal assemblage. The upper seismite horizon is under- and overlain by faunal elements of the ELMZ MN 6 to MN 6/7, strikingly consistent with identical faunal elements that occur in the lowermost Steinheim crater lake deposits; ELMZ European Land Mammal Zone.
