Need Help - Unknown Specimens

[Arsenal]

I have recently come across some rocks/artifacts that look to be worked but are unknown to me.




The piece with three humps appears to be pottery but that is not my strong suit. The one with the lines has me just clueless. The lines were too congruent to not be man made, I THINK.

The two pieces that appear to be some kind of bones (??) were found together. The hole on the larger piece is very precise.

The last, small piece is not a point, but what is it??

As always any help is greatly appreciated!! Thank you in advance.

I thought these were all pretty odd and foreign, at least to me.

Any wild guesses?? Thanks!

Your 1st, 2nd and 3rd look to be modern day pottery that has been in the creek for a while 4,5,6 and 7 are natural rocks. The last photo is a preform or a small knife blade. Cool finds and welcome to T-net
