Transportation may be minimal where vertebrates are in marine or lacustrine sedimentary basins. Organisms may also be transported considerable distances by the agencies of predators, scavengers, fluvial systems, and be marine currents.

The transportation may result in specific orientation of skeletons, in most cases stable positions are horizontal, with specific sides up or down.  Trampling, bioturbation, plant growt and soil movement can disturb this pattern into near vertical positions.  Fossil skeletons in life position indicate rapid burial.
