Glaciers mix things around a lot, but it would be possible to find out where the glaciers crossed and what flint-bearing deposits are in that general vicinity. However, harbors also contain an assortment of ballast stones, picked up by ships around the world whenever they needed a little extra weight. Thus, the origin of the specimen is pretty uncertain.
Note that some fossil brachiopods can also vaguely resemble cardiids in general shape and sculpture.
