ID possible?

Found this trunk in a dumpster 2 months ago. Looked like a dead trunk with some tapêr. Potted it in mostly pine bark. Sprouting sharp long leaves now. Anyone an idea what this could be? My guess would be
beaucernea recurvata or cracilis?

To me it looks like a Yucca species

A fairly old yucca too.

Thanks guys. Yucca elephantipes - after some elaborate screening on different yucca barks. Will go indoors after summer.
