New Members dhavlena Posted November 11, 2009 New Members Share Posted November 11, 2009 HI New here so please excuse any mistakes. Can anyone help me identify just what kind of coral I've got here?? They are paddle shaped, from 4" to 6" tall & are fairly common at the nearby Rockport Quarry (now thankfully owned by the state of Michigan). I've been searching the images on Google (& elsewhere) for over a week and have found nothing like these paddle-shaped corals that taper to an attaching base. ONE PHOTOS ATTACHED _ TRIED to attach two, but system refused it! Will try to send 2nd, different angle, photo in another posting. Rockport's a great place if anyone finds themselves in northern Michigan! THANKS Dennis Havlena dhavlena@gmail.com www.DennisHavlena.com Link to comment Share on other sites More sharing options...
New Members dhavlena Posted November 11, 2009 Author New Members Share Posted November 11, 2009 ME again -- here's the 2nd photo of the paddle-shaped corals that I couldn't get on my first posting a few minutes ago. Please let me know if I'm doing things wrong. Thanks Dennis Link to comment Share on other sites More sharing options...
jkfoam Posted November 11, 2009 Share Posted November 11, 2009 Dennis, They appear to me to be the tabulate coral Favosites favosus (Goldfuss). JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...
crinus Posted November 12, 2009 Share Posted November 12, 2009 (edited) These corals are Hexagonaria. In Michigan they are more commonly known as Petoskey stone. These are not water worn as Petoskey stone is. Go to the Michigan Basin fossil site (http://strata.geology.wisc.edu/mibasin) and search under Hexagonaria to see some other examples. The overall shape has nothing to do with the type of coral. It is the individual coralites that determine the kind that you have. crinus Edited November 12, 2009 by crinus Link to comment Share on other sites More sharing options...

Guest solius symbiosus Posted November 12, 2009 Share Posted November 12, 2009 These corals are Hexagonaria. I think that they look more like a columnariid or favositid than a disphyllid. Dhavlena, can you get a close up of an individual corralite? Link to comment Share on other sites More sharing options...

Let me know if any other photos would be helpful Dennis Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted November 14, 2009 Share Posted November 14, 2009 As the columnariids are restricted to the Ord and Sil rocks from Laurentia, I think that jkfoam nailed it. They are probably Favosites, though a longitudinal image would be nice. Link to comment Share on other sites More sharing options...
