Morphology
The compound is a regular adjective+noun composition: 'fossorial' means adapted for digging and 'foot' is the body part, so the phrase directly denotes a foot adapted for digging. This compositional pattern is predictable and cross-linguistically common, so a B1 learner who knows both constituents would understand the meaning.
Etymology
Fossorial foot comes from words used to describe animals that dig: fossorial means 'digger' and a strong, shovel-like foot is used to move soil. So, fossorial foot means a 'foot adapted for digging'.
