Looks like a solitary rugose 'horn' coral to me.

Or rather the mold of one.

Where was it found?

Pretty.:)

Rogers Arkansas in a creek bed. We had some rains and the water was up but was down today. I went hiking down a creek bed. The bed is about 4 feet lower then ground level. The two holes are different in the same rock.

These zigzags are the edges of a bed of bivalves. They have rippled edges similar to scallops. Could be Pectinidae, Ostreidae, or something else, but definitely look like bivalve shells.

I refuse to give up my childish wonder at the world.

Thanks. Glad I picked it up. I almost dropped it because I was over half a mile back on a creek and a 4 pound rock was not fun in my coat pocket.
