Congrats to The Brummell who came closest with the suggestion that the spines were of an ancient shark, similar to the modern spiny dogfish (Squalus acanthius). Indeed, acanthodians share many characteristics with sharks.
That was extra tough, don’t worry the next one will be easier!

I guess I did come the closest, but I think I still missed by about 100 million years.
I like these mystery fossils (and not just because my current win rate is 100%).
