Morphology
The meaning ('copal that has been partly mineralized/ancient copal') is directly compositional from 'fossil' (ancient/remains) + 'copal' (tree resin); a learner who knows both words can infer that this refers to copal in a fossilized or aged state. The noun+noun modifier pattern is a straightforward, cross-linguistically common way to indicate an X that is fossilized, so the phrase is transparently derivable from its parts.
Etymology
Fossil copal comes from fossil + copal and gives a clear picture: copal is tree resin and fossil shows it is old and buried, so it is resin that has partly hardened underground. That's why fossil copal means an in-between stage between 'resin' and 'amber', and why it is often used as cheaper jewelry material.
