Hit a few local beaches this week to do some sharks tooth and fossil hunting .
got a bunch of shark teeth over the past week or so. and a few odd little pieces i could use a little help with ID`ing
#3-4-5 approx 1 inch long ... #1-2 approx 1 inch long ... #14 longest object approx 6 inches long
TY for any help ... H.H.

1) mouth plate (stingray?)
2) vertebrae (prob fish of some kind)
3-5) wow that's weird. no clue
14) hard to say from pic, but I think not coral; probably worm tube casts

rem, scale always helps.

Thank you for the ID`s ... here is a scale photo on the other object ...

Well, its killing me that no one knows what this thing is, so I am going to hazard a guess to hopefully get something started:

its a sponge fossil.

been doing some eyeballing around.
looks like # 14 may be fossilized coral
think you are right on the last item, appears to be fossilized sponge, and a pretty nice little one.
here is a link to one that has the same shape.
