Pippa posted a topic in Fossil IDI picked up this jasper for its banding. Only later, when checking the rock through my hand lense did I discover what I think are a bunch of little rugose colonial corallites at the top and bottom of this rock. If these are indeed corals, all but one lack most detail in the center. If septa are faintly visible, they look differently preserved than on any of my other coral specimens. Mostly it's just circle after circle here, and areas full of "pores". Now that I'm looking at them on my larger screen, the "pores" themselves seem to be corallites - microscopic ones. The black dots are in the center of honeycomb like shapes. I'm confused now, are these the fossilized remains of one or two type of corals, or maybe a colonial coral and a bryozoan? Sorry about the bad quality and distortion of the pictures taken through a microscope lens on my phone. Please help me ID these tiny hurricane look-alikes. As always, thanks in advance. Here a couple of them in various states of preservation. Lots of them have a vug where the center of the corallite would be. Here the circles look like growth rings and in some areas the "pores" are clearly visible. #1: This one is the only one with detail in the center. Septa? #2: a vug at the center seems all that's left here. #3: Just pores in the center, and in between the circles, maybe the faintest lines that could have been septa? #4: Area in between corals, with faintly visible honeycomb shapes: Detail of the above: Another area in between, looking somewhat different again:
