Crossbedding and horizontal bedding formed by antidunes in a laboratory flume are described. These structures are characterized by faint lensor wedge-shaped bodies and by entirely low-angle laminae. Although bed-forms were destroyed by waning flow, some of the internal structures were preserved so such structures may be expected to occur in ancient rocks.
