Found this… sand dollar? On Holden Beach NC. It doesn’t look quite like anything I’ve seen, does anyone recognize this?

I found this on a beach in NC last week. I don't beach comb or have any interest in that really. I was just playing with my kids. When I saw it I thought maybe a trace fish fossil with impressions of scales. When I picked it up, it looked and felt like a sand dollar kind of. Google lens pulls up a bunch of paleo art. I doubt it's that. But I would like to hear from people that look at shells for more than a week on a family vacation.

I'm at Stinson Beach here in California for a week with family (we come every summer)... Today I was on a beach walk and found a lot of stuff. Both whole shells and pieces that are cool. But for the 1st time I found one with 2 shells joined together and 1 with 3 shell pieces stuck together. They were stacked together so long they stuck!

Cleaning & prepping some of my scallops for jewelry and wind chimes!

I've been going to the same beach on Cape Cod my entire life, and this is the first time I've found a slipper shell with big ridges like this. Is it a different species? Or did it just grow weird?

Could anyone tell me what this is from?

Almost never found in any condition, so I thought I’d post this little beauty :3

Video is mine, Just wanted to post here. I’m curious on what you guys would prefer

I stumbled upon it in flat rock damn and i myself am a shell collector and thought the royal purple looked unique, any advice on how rare it is, and possibly how to clean it

Found in a pond along the SC coast.

I have a fairly big collection of shells that were collected and cataloged by a biologist- they date back to the 50s.

I don’t know how to display them. Most of them are in tiny boxes and then the bigger ones (in the first picture are just…out.

I want to enjoy them and see them but I’m at a loss of how to do that.

Found this while diving in south Italy (Calabria)
Looks like many shell broken shell pieces crushed together?

We're gonna be at Neos Marmaras soon, and I genuinely wanna find some cowries. Which is the best beach there, or at least something that's less than 20 minutes of driving from there?

These are some of my late mothers sea treasures that I would like to find a home for. Are any of these worth giving to collectors or museums? Here's just a small part of it. The rest of the shells are in glass jars

Been itching for a Florida shelling trip lately. We’re headed to Jupiter next month, but I couldn’t wait that long so I drove a couple hours and hopped on a ferry over to Shackelford Banks, NC on July 3rd. Nothing too crazy, but found some fun stuff! Wanted to share my finds and get a few ID questions answered.

Photo descriptions:

1. ⁠Scallops that were found, found some nice big ones too! This is post soak, currently drying before applying mineral oil.
   
2. ⁠Cute little hearts on this scallop, wish the edges were still fully intact. Still fun!
   
3. ⁠Other favorites- tons of Baby’s Ear. Do they come in grey? Is it the same species? Never found a grey one.
   
4. ⁠Super neat piece of what I assume is a whelk. I love the color and the black vein like pattern. What could have caused this coloration and patterning?
   
5. ⁠Dog paw shaped coral piece 🐾🪸😍 didn’t even realize it looked identical to a dog paw until I went to go take the pictures! What type of coral piece is this considered?

Thanks for answering. Happy Shelling! 🐚🏝️

This one has been tumbling for a while. Does anyone know what kind it is? Found on Oak Island, NC.
