Was this a scallop pearl?

I ordered seafood Alfredo from a very well know seafood restaurant while I wait in my school bus for the next 5 hours for my team to get done. I'm chewing on a sea scallop and bit something very hard. I took the scallop out of my mouth, and this was stuck in it. It was 1 weird shaped piece, but I think when I bit it it cracked into 3 tiny pieces. It's like 3 little balls that were joined together. I googled it and the only thing I could come up with is scallop pearls, which I didn't even know were a thing until just now.

I'm not sure if this is the right place to post this or not.
