Environment
Lithology: sandstone
Taphonomic context: fluvial deposit
Habitat comments: Bed D6 is comprised of fine-medium-grained, light-yellow sand
Bed D6 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
