Flint is a sedimentary rock so fossils are possible. Not sure what that ring is, but I can tell you what it's not. It's not a crinoid fossil as they were from the Mississippian time period and long gone by the Cretaceous period when your flint was formed. Gary

Crinoids are still alive today: https://en.wikipedia.org/wiki/Crinoid

The ring seems to run through until you see it at the bottom picture. Thanks for the response much appreciated

Flint like that is nodular. A concretion. Some of the nodular flints over here show concentric banding like a bull's eye. I'd guess it's something to do with that. Gary
