The fourth age of the Cambrian period (the time when the fourth stage of the Cambrian system, ie. succession of rock, was laid down) does not yet have an official (ICS) name, but it is informally known as the Botomian after the [[Siberia]]n-[[Kazakhstania]]n stage corresponding to its earlier part (its later part corresponds to the Toyonian).

The fourth age of the Cambrian period (the time when the fourth ''stage'' of the Cambrian ''system'', ie. succession of rock, was laid down) does not yet have an official (ICS) name, but it is informally known as the Botomian after the [[Siberia]]n-[[Kazakhstania]]n stage corresponding to its earlier part (its later part corresponds to the Toyonian).
Relative to later ecosystems, the Cambrian ecology was extremely delicate. This may be due to the fact that diversity was very low, compared to modern ecosystems, and so environmental disruptions could easily wreak havoc (we are witnessing the groundwork of what may well be a similar disaster today - human stupidity and short-sightedness means that large areas of wilderness and biodiversity are being destroyed, to make way for extensive fields of ecologically vulnerable monocultures.)
