Funny coincidence (?!)

I was studying for my Geology test coming up and I had to make an acronym to help me remember all the Periods of the geologic time scale. Here's the first thing I came up with:

(Periods) Acronym

(Cambrian) Can

(Ordovician) Our

(Silurian) States
(Devonian) Dig
(Carboniferous) Coal
(Mississippian) Mines
(Pennsylvanian) Permanently
(Permian) Providing
(Triassic) That
(Jurassic) Juries
(Cretaceous) Continue
(Tertiary) Treating
(Paleogene) Poor
(Quaternary) Quadrupeds
(Neogene) Negligently?

This college has burned environmentalism into my subconscious!

P.S. Sorry it's so hard to read. This dang blog program makes it hard to make separate lists...
