Law and Diplomacy in Commodity Economics C. to C. acid units are characteristic of the free fatty acid (FA) fraction of epicuticular waxes. However, TEM and SEM investigations of the fossils revealed no evidence for cuticle preservation, and while a contribution from cutin cannot be excluded, the aliphatic component of the fossil polymer

https://doi.org/10.1057/9781137318107, living relatives of the eurypterids, showed that C. and C. fatty acyl moieties likewise dominate. Assuming that the original composition of the eurypterid cuticle was similar to that in living chelicerates, fossilization likely involved the incorporation of such lipids into an aliphatic polymer.
