Hello. Can anyone help me to identify these types of rocks fossil? It was found on Indian River Lagoon Stuart Florida. Thank you very much in advance for your time and help.

Kindly,

Stephanie

I believe that type of rock is called a coquina.

If You want an id on the shells in it better close up pictures of the shells will be needed.

Please include a scale.

Agree with Tony. This is one of the coquinas you run into down here. Given the location and general color it could be from the Anastasia formation which shows up along the coast. I cant tell you which pelecypods/clams ...I've seen the same apparent species up on beaches weathering out in Melbourne... 

Here's several photos/references:

Great! I will have weighed specimens included in my specimens from here on out, as well as a couple of close ups...Thank you so much yet again. You don't know how grateful I am to have a site like this. I wish I could give back (Knowledge) to the community rather than just "What is this, what is that?" I hope to someday become as seasoned as ynot, doushantuo and Plantguy (I love plants too!) and be able to share my learnt knowledge with others in the future.

The scale needed is for size not weight. A ruler works best.:D
