Coral Skeleton .. or might it return!?

[SnowManSnow]

Hi.. I noticed this on a piece of Fuji LR that I picked up today (finally have all the rock I want in my tank!). It LOOKS like a coral... it's hard... but is white like a skeleton... will it come back with appropriate lighting? Or is it an organism long gone?

Any ideas?

Thanks.

Here is somthing else that probably USE to be something... a dead shroom? THis particular rock has 5 or 6 of these spots on it. Is it long gone too?

Believe it or not this tank is a LONG way from where I started a month ago.. actually from nothing! Appropriate lighting should be in the near future although I MAY have to wait till NOv. .. when my brithday rolls around haha.

Have a great night everyone!

Both are stone dead. The upper looks like a Faviidae coral. The lower looks like a Bryozoan colony.

They probably are dead, but who knows what else might pop up. I purchased the "garf grunge" to start out my tank 2 months ago. This week I found 3 small pieces of crushed coral fragments that have small polyps beginning to pop out of the small holes. At first I thought it to be diatom fuzz, but alas they retract into the holes if disturbed. I think they might be some form of a plate coral. Sorry no pic to post but hopefully for christmas. I know the feeling of running a saltwater on a shoestring budget. I've deceided to sit back and watch the tank mature for a while before I try to add much more.
