    Probably fossil sponge.

     

    You can understand the pattern/structure you see in your speciment better if you look at the amazingly good specimen, which happens to be Ventriculites

    That's from the NHM web site, but I can't link to its page directly; please go here to read the associated description - http://www.nhm.ac.uk/kids-only/earth-space/fantastic-fossils/

     

    Fossil sponges are very common in flint. In fact there's a book 'Fossil Sponges of the Flint Nodules in the Lower Cretaceous of Texas'. I'm not suggesting you get/borrow it.

     

    I can't sompletely rule out coral. Maybe somebody else could help decide...
