Notes

[1] We use the Russian-Kazakhian stages until the ICS gets around to finally giving these Early Cambrian ages some names.  As of this date (041118), the ICS Early Cambrian Epoch is undivided.

[2]  We use chaotic in its mathematical sense, meaning that the end state of a closed system is extremely sensitive to initial conditions.  The classical example is from meteorology, in which the occurrence of a hurricane is supposedly determined by the wing beat of a butterfly six months earlier and ten thousand miles away. 

[3]  These peculiar names are English corruptions of French corruptions of Micmac (Amerind) place names.  Escuminac and Miguasha actually have very pedestrian meanings: "Lookout Point"  and "Red Cliff," respectively, thus proving that the original inhabitants were just as unimaginative as the French and Tory settlers who replaced them.
