Over millions of years, the island's shoreline vegetation fossilified, preserving a snapshot of ancient ecosystems.

Over decades, the committee's informal practices began to fossilify, resisting any attempt at reform.

Fossilization of soft tissues is rare, but under the right conditions it can preserve delicate structures for millions of years.

The geologist examined a fossiliferous sandstone bed and was excited to uncover numerous well-preserved shells.

She spent her summers exploring the fossildom along the coastal cliffs.

The strata were fossiliferously packed, yielding countless specimens to the paleontologists.

The clay layer was non-fossiliferous, suggesting rapid deposition in an environment hostile to organism preservation.

Soft tissues are rarely fossilisable unless exceptional chemical conditions preserve them.
