And Anthrozoic and Psychozoic and many others.
This reminds me of the figure from Lapworth's 1898 _Intermediate Text-Book
of Geology_ (which is in the excellent _Supercontinent_ by Ted Nield) which
includes a number of geochronologic units that have since dropped off. Some
of them are actually useful heuristically: a Protozoic (Cambrian-Silurian)
and Deuterozoic (Devonian-Permian), and a Neozoic (Mesozoic plus Cenozoic).
On the other hand, it includes the redudant Quaternary Cycle, Anthrozoic
Life Period, and Post-Tertiary System.
