Hey, new here! My 5 year old found this in the yard. We're in NC about 1 Mile from the Cape Fear River (literally back yard). We're also about an hour or so from beaches. I found some pictures it looks like Disphyllia Wangi which I'm thinking is coral from France. It also looks like it's possible honeycomb? I'm no archeologist, but my 5 year old has always been super interested in nature particularly anthropology and archeology. I'd love any help our resources to identify this and fuel his journey.
