Fossil coral,moss?, bryozoan

I picked this up at the flea market. He told me it was petrified moss...which I dont think it is. Im thinking coral but I wasn't able to find the answer after some research. Its from Arizona and was collected in 1968 and its jurassic in age. Pretty cool fossil.

I suspect it's a rather beautiful sponge. The long rods and "flowers" look like spicules. I'm not convinced it's Jurassic - I've seen Palaeozoic ones resembling that - though sponges are massively diverse...

 

EDIT: I probably let my imagination run away here and travertine/tufa moss or other plant is probably right - see comment below by DPS Ammonite.

An extremely large version ?

I thought they were microscopic.

Never seen a sponge or fossil like that from Arizona. 
 

It might be travertine limestone covering plant material; the label says “moss”. Note everything is hollow; (covering plant material.) If it is travertine, I doubt that it very old; it looks very fragile. Anything very old would have been crushed or the spaces would have been filled in with sediment or another mineral. It is probably Tertiary. Maybe a paleobotanist could help. @paleoflor
 

Does it fizz in acid?

I was imagining an etched out silicified specimen but I think you're probably right. :)

Hi, thanks for your response. Im a little confused when you say covering plant material. So are you saying it is more recent but just got covered by limestone and is preserved...aka not a fossil? Its actually not that fragile at all. Its a pretty solid chunk. I mean im sure its not the strongest fossil out there but I dont worry when I pick it up or put it down. Here are some pics of the back to help.

That almost looks like the same rock and “fossilized” plant. 
 

Could you please translate what kind of plants it is covering, age and formation that it is from.

Limestone from a spring or limestone rich stream covered plant material which has since rotted away. It is a fossil if it is more than 10,000 years old.  Regardless, it is a very nice piece.

Ah okay. Cool, thanks. So are we undetermined if it is older then 10k?

That's from the "ager tiburtinum" plain  (Agro tiburtino, being Tiberis the latin for Tiber River), east of Rome, near Tivoli, not far from the Emperor Hadrian’s Villa.
Holocenic in age and encrusting mainly Carex sp., Thypa sp. etc.

I bet this would study well as a CT scan.
