Capable of being fossilized or turned into a fossil.
From fossilise (British spelling of fossilize) + -able (Latin habilis 'able to be'). The suffix -able indicates something that can be done or is possible.
This British spelling variation reminds us that English evolved differently in different countries—in Britain they kept the 's' from fossil, while Americans switched to 'z' following French patterns. Both are correct depending on where you are!
