Water transport is a frequent taphonomic agent in continental environments that may affect
and disturb original bone associations. Fossil allochthony occurs as a result of
resedimentation (before burial) and/or secondary deposition (after initial burial) altering
palaeoenvironmental and palaeoecological indications provided by fossils. Skeletal element
sorting or preferred orientations of fossils are evidence of fluvial transport as studied by
several authors. Bone surface abrasion is another trait recorded on fossils that may provide …
