Suita - 巣板

Suita are best known for their telltale and eponymous Su; small holes that were formed by escaping gases during the lithification of their specific stratum.

However, It should be noted that the presence of what appears to be Su does not qualify that stone as Suita; there were only a few layers, or strata, that produced Suita, and only stones from those layers are actually Suita.

Additionally, not all Suita have Su; a Suita without Su is known as Sunashi Suita.
