Yeah, I'd never seen one do tha either, dunno. There's a bunch of them around here and I've never seen it before either.
It was only the anteriors too which is what mede me look deeper into the core for the answer.

They seem to be a fairly good tooth generally from the little I know of them. No idea.
For all I know these were on a card in the techs live mould setup for 10 years.
