Cape Cod arrowhead?

[simulant]

Found this in the breakwater on a Cape Cod beach in Hyannis. The edge looks somewhat serrated. Do you guys think this is an arrowhead? If so it'll be the first one I've found ever!

The second piece I'm taking a gamble on only because it doesn't look entirely natural. It's completely flat on one side and has that notch in it. Suppose it could just be a broken rock. I'm definitely green in this area!

Thanks all.

Well the flint looks like a triangular type of a point. If it isn't broken. The 2nd one is probably just a rock but maybe somebody else will see something different. Nice finds, rock

Thanks rock. I did some searching around and I think this is probably a Levanna triangle projectile point.

The triangle looks like a point to me too. I would have kept it.
