History is literally right under our feet, we just need to find it.

The conspiracy begins.....

Previous investigations found that the vessel's timbers had been damaged by burrowing holes of Lyrodus pedicellatus, a type of "shipworm" typically found in high-salinity, warm waters -- a sign that the ship, at some point in its life, made a trip to the Caribbean, perhaps on a trading voyage. Martin-Benito speculated that the infestation might have been one of the reasons the ship met its demise just 20 or 30 years after it was built.

Typical for ships like these to have a life expectancy of 20-30 years, looks like its been used to fill a site in order to build on top. This was rinsed and repeated as standard practice back then.
