minnbuckeye Posted June 14, 2017 Share Posted June 14, 2017 A recent trip to Coralville, Iowa provided me with these coral specimens, each unique in their own way: 1. I posted this a few weeks ago prior to removing most of the matrix from it This rugosa coral was huge!! Check out the scale. 2. The next coral might be mistaken for a mushroom: Oops, I meant this one: 1 Link to comment Share on other sites More sharing options...

Jeffrey P Posted June 15, 2017 Share Posted June 15, 2017 Those are three totally awesome specimens. Corals are not a primary feature of my collection, but if I had those they would be. Congratulations. What age or they? Link to comment Share on other sites More sharing options...

Doctor Mud Posted June 15, 2017 Share Posted June 15, 2017 Wow! I'm not usually excited by coral but these are awesome! Link to comment Share on other sites More sharing options...
doushantuo Posted June 15, 2017 Share Posted June 15, 2017 In the first picture,there SEEMS to be a change in growth direction,the reorientation of the alar plane probably means reorientation to the current direction . The second possibility is regeneration at an angle. Link to comment Share on other sites More sharing options...

The second possibility is regeneration at an angle. It seems like many rugosa corals that I find do this and I have always wondered why. My experience shows that the larger the rugosa, the more likely for redirection. In my mind, I equated it to weight, causing it to tip over, then regrowth at a different angle. But that means it would have to be dislodged at the base. If this happened, then it likely would have tipped over. So I will go with the flow, meaning a change of current to explain it. Thanks.
