My terminology knowledge suddenly fails me: in this context is "distal"
relative to the marine or the terrestrial end of the estuary??

Sigh, well given that provenance, the status indeed is ambiguous.

I know of no reliable way of determining if a single fragmentary

is probably more often allochthonous than otherwise.
