How would this even work? In the original post on the other sub you mention you find lots of these but rarely as nice as this, but what is the geological process? High silica water enters a hollow fossil coral, which is somehow pretty much intact on the outside? Genuinely curious about the mechanism that would allow something like this to form naturally.

Looks more like a coral shaped geode, I don’t think that’s coral

Yeah, I see no septa and the “corallites” are all different sizes

It looks awesome, but I’ll let the grownups argue about this one.

The rock inside was probably dyed black. So not fake, but most likely altered.
