<<<The PR says "large concentration", "concentrated" and "compact" to describe this new area. So, we have a large variety of artifacts in a compact, concentrated area from a colonial era vessel that "came to rest on the ocean floor.">>>
The PR did not say there was a "large" variety, Goldenboy... only that the variety "includes standing rigging, ships fittings, rope and wood fragments."
That may very well be all there is down there in that particular "compact, concentrated area."
