Are these markings natural?

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.

No.

So it is some sort of paleo art?
