The earliest Phanerozoic hardground occurs from the middle Cambrian of China.
- class="label">•
The hardgrounds develop on oolitic grainstone, oncolitic wackestone, and microbialite.
- class="label">•
Microbialites encrusted hardgrounds, whereas macroborers were generally absent.

Metazoan encrustors and macroborers could not inhabited newly appeared hardgrounds.

Additional evidence of middle Cambrian calcite sea is presented by hardgrounds.
