What coral is this?

I thought it was small piece of GSP but after zooming in, it doesn't look like it.

1st is probably green sinularia. Not sure on the other one. Stoney base?

First pic was size comparison actually.

I found this small piece a few days ago on the gravel. It is attached to a single piece of crushed coral.
