Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit
Habitat comments: Bed D7 is comprised of Large-medium grained sand with iron oxide, small gravel, washed carbonate concretions, mollusc shells, and "gray clayey clumps"
Bed D7 is part of the ancient alluvial deposits around this section of the Khoper River and seems to have been deposited by a rapid current close to the bank of the river
The rapid current may have washed out the faunal remains and deposited them downstream
