two tone green capsule with no imprint.

Im trying to identify this capsule. it was found in a skelaxin bottle but judging from the other misc pills found in that bottle i doubt thats what it is. It is dark green on one half and lighter green on the other half and has no imprint whatsoever. anyone have any ideas?
thanks.

i know its a shot in the dark and probably wont be identified. but here is a pic if that helps.
