Abstract

A recently proposed subsystem scale seeks to overlay a threefold subsystem scheme onto the four-series Cambrian. It does this by uniting the two lowest global series within a single subsystem, whereas the remaining two subsystems coincide with the global Miaolingian and Furongian series. This is an impractical scheme, strongly influenced by historical precedent, and an alternative scheme of two subsystems, each comprising two global series, is here proposed.
