Another new Graham Sumner book?

[Duncan Head]

That still does not explain away that it is apparently a Cathaginian wreck and not a roman one. The pottery does indeed point out towards the III Century BC but the remains are Punic along with North African Amphorae.

(Sorry its in Spanish)

While the culturaclasica link refers to Punic amphorae of C3 BC, the d'Amato book refers (p.224) to the cuirass:

"coming from a Roman shipwreck and found together with amphorae of Dressel 20 and Dressel 38 type, i.e. dated around the beginnning of the first and the end of the second centuries AD."

So there seems to be disagreement about the ceramic dating evidence. Does anyone have access to a more detailed report? Could there be stuff from more than one wreck in the cave? How certain is it that the cuirass is associated with the amphorae (whatever the date)?
