Fassaite?

This is quite interesting! It may be a Fassaite specimen? Google suggests that, at least, when you search for “fassite” – as it appears someone once wrote on the tape attached. And, it looks like other Fassaite photos? However, if the writing says “Fossil” instead, it’s plausible this could be a fossil as well? Bets are it’s Fassaite, but no guarantees.
