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
fossil is autochthonous or allochthonous. In fact, a single fragment
is probably more often allochthonous than otherwise.
The peace of God be with you.
