Which item or items uncovered at an archaeological dig would indicate that the site probably dates from the mesolithic era rather than the paleolithic?

The choices can be found elsewhere and as follows:

a small dugout canoe
clay pottery shards
a chipped-stone harpoon head
several finely shaped bone needles

I think the correct answer would be the first option The item uncovered at an archaeological dig that would indicate that the site probably dates from the mesolithic era rather than the paleolithic would be a small dugout canoe .
