Autochthonous deposits are autochthonous, because they show no signs of transportation.

You shouldn't differentiate between "current and autochthonous", but between autochthonous and allochthonous. Latter indicates transportation of the fossil away from its original deposition place. Even this transportation might me chaotic and not perfectly oriented in one direction, depending on the flow rate and the fact what flows there (water, debris).
