"Over 70 different types of shells were discovered and identified during the recent excavations at the historical site of Jiroft," he said. "At least seven types of the discovered shells were edible, showing that Jiroft residents were in the habit of eating shellfish"

Am I the only one who notices how much this fails to follow?

They found 63 types of shell that aren't edible. That would appear to prove that shells got there for a reason besides eating. Maybe the sea wasn't where they think it was, then. Maybe sea shells were money. Maybe collectors collected collections. None of which have anything to do with eating.

Re #9

You know, if you are part of the crew digging the site and ask too many inconvenient questions like you did, you could be dropped by the archeologist(s) in charge.

Just hail the boss.:)

I noticed that the text says "at least seven types... were edible" and that a number of the rest were extinct (meaning that there's no way to know for sure that they were edible). In any case, perhaps they ate the edible kinds, and used the others for something else, such as dyes, apparel, or decoration.
