How to play this prompt
Strategy notes specific to “Name a type of fossil” — not generic advice.
Science prompts reward precision — the vague version of your answer is common, the exact term is rare.
Your edge here is Coprolite: specific, valid, and far from the crowd's first thought. If it feels slightly too obscure to say out loud, that's usually the sign it's worth real points. Bank Trace fossil as your backup — same logic, different answer.
The trap is Fossilized bone — correct, but it's the reflex answer for a reason: it's the first thing the category suggests. Ammonite is the same story. Typing either one puts you shoulder-to-shoulder with most of the player base at 10 points.
Cast fossil and Imprint fossil are the honest middle of this prompt — answers most players know but few type first. If your instinct answer feels too easy, reach for this layer instead of the obvious.
Build yourself a mental shelf for this prompt: Mold fossil, Petrified wood, Trace fossil. They're different answers, same rarity neighborhood — and that neighborhood is where dives are won.
Rated 4/5 difficulty — only 12 banked answers, so matching the bank is genuinely hard. Precision matters more than speed here.
