Found these walking along the beach, no clue what they are. The one in the middle we found first, very light in the hand and chalky to the touch. The curvature is weirdly perfect, and nothing like I've seen before. The one on the left was found second, my mother claiming it felt similar to the first one I found (middle). This one seems a lot more like a rock in texture, lots of tiny holes in it and is heavier than the first one I found. Of the three, it's the one I am least confident in being a bone. The third one I found (right) was one I found walking back up. It's very smooth and polished to the touch, one side of the tubes is open and hollow like a straw, but it is closed up on the other side. My father suggested it may be a tube worm of sorts. All three were found off of the sand and in the rocks.
Looking for any help identifying these three, if they are even bones at all. If these are very common in the North American East Coast, I sincerely apologize as I am from the prairies and from nowhere near the region.
If anyone has further questions, I still have them and I am happy to answer any further questions from you all. Thanks in advance!
