And the symbol for Cambrian is not a 'C' anyway but a 'C' with a line
through it. Carboniferous has a straight 'C' and Cretaceous has a 'K'
(Kreide = chalk in German). By the way the 'Tertiary' does not exist
anymore. The Cainozoic begins with the Palaeogene followed by the
Neogene Systems each of which is subdivided into Series such as
Paleocene, Eocene, Oligocene, etc.... so that some formal
systematics in the upper part of the geological column makes it
comparable with formal System breakdown in the lower part of the
geological column, e.g., Silurian System - divided formally into
Llandovery, Wenlock, Ludlow and Pridoli, on a global basis, ratified
Thought you might like the up-to-date stratigraphy that is now formally
accepted. I suppose the boundary should now be the K/P boundary!
