  • Understanding how materials move under the ground after sedimentation has taken place is still a problem for taphonomists due to the constraints imposed by certain diagenetic processes to create analogical frameworks through experimentation where variables are hard to control. The present study addresses one of these processes and provides important information regarding how bones move horizontally and vertically in clay sedimentary deposits. An experiment was conducted for one year and the clays were exposed to periodic cycles of wetting and drying. The results indicate that plastic sediments are prone to modify the original position of bones. Bones move vertically but mostly without tilting. Vertical tilting is mostly associated with trampling or other (e. g., bioturbation) processes.
