Possibly one of the horn corals in matrix.

I am with Fossilman - thinking deathplate. ((Besides petrified deathplate sounds way more hardcore than petrified flowers ))

Spheroids are possible if it was formed in igneous material.

I don't know, a cab of "petrified flowers" sounds pretty good to me.

Looks like a combination of starburst jasper and leopardskin orbs to me.

Great word Ted - rugose! Love it.
Like the stone in the OP too. Looks marble'y to me. Like a "fireworks" marble.

That's it. i agree about the rugose coral. As Don mentioned, horn coral. May still be off though.

I'm kind of with the non fossil origin folks. I've seen several types of ryholite with those starburst type patterns that resemble fossil symmetry but are not fossils. Answer is simple really. Drop a little acid or scratch test on a corner of the matrix. If it fizzes or scratches, it's probably limestone and fossil coral. No fizzy, no scratchy, harder matrix likely rhyolite.....Mel

This one is marble, or is it dino bone? Doesn't have to be organic origin to look organic

as fossils get mineralized/agatized, quartz replaced , they lose their original structure to varying degrees , even to total loss of structure . this specimen still has some structure. Rugose corals were solitary corals but lived in close proximaty in favorable environments . specimens can be found with multiple corals very close , but there is usually a matrix of seabed between . the mineralization is often different of the coral and the matrix . can be quartz corals and pure limestone matrix,quartz corals chert/jasper matrix , calcite corals calcite matrix,others . the acid test does not work on quartz replaced fossils. but does on lime/calcite . if it does not fizz does not mean it is not fossil . anyway i think the pic looks like fossil coral .

Hi Lee my 2 pennies woRTH is that it is an anomily, (did I spell that right)jasper. Doesnt look like a coral to me. Do you know where it came from? Hard like jasper?
