Jargon Run Amock?

Jerry wonders:

"keystone megaherbivores" -- a good name for a band?

(Gill, et al., page 1100 of current issue of Science.)

That's real nice terminology, actually. You can almost see the elephant, or dinosaur, or mammoth chewing its way through a tree's canopy.

And far below, scrambling through the leaf litter, evanescent microcarnivores.

Jerry replies:

My definition:

Keystone megaherbivore: A large salad eater from Pennsylvania.
