Morphology

tar + pit

The noun phrase 'tar pit' is transparently compositional: 'tar' (viscous residue) combined with 'pit' (a hole) yields the straightforward idea of a hole containing tar. A B1 learner who knows both words can infer the basic meaning easily, although specific geological or paleontological details (e.g., preservation of remains) are additional factual knowledge.

Etymology

Tar pit comes from a simple, literal image: a deep pit filled with thick, sticky tar where animals could step in and get stuck. Their bodies and bones stayed in the black tar and were often kept for thousands of years, so the name now means a natural place that 'traps' and 'preserves' ancient animals.
