Hi, @jonelle-forbes – Hope you don’t mind that I moved your post into the ‘What Is It’ forum. Â Do you have any further information you could share about these finds (city/state info, did you find any of these on the beach, etc.)?
From a quick glance, it appears that you have quite a lot of quartz/agate pebbles. Â Quartz comes in many different colors (see here:Â http://www.minerals.net/mineral/quartz.aspx).
Your second picture appears to have mostly modern invertebrate shells and coral pieces. Â The specimens at the top of that picture might be fossilized, but I’d need individual pictures (with something for scale — do you have a penny?).
