MainefossilRocks Posted February 16, 2021 Share Posted February 16, 2021 I have two fossil rocks like this one, around the same size. I find these in the Telos Lake to Frost Pond range in Northern Maine, around the Chesuncook Dome. Brachiopods everywhere, but this one is odd. Coral or something? It has a little depth to it, and graduates deeper towards the center. Link to comment Share on other sites More sharing options...
FranzBernhard Posted February 16, 2021 Share Posted February 16, 2021 Welcome to TFF from Austria! It has something of a favositid coral to it. But I am not totally sure. @Rockwood? 29 minutes ago, MainefossilRocks said: It has a little depth to it, and graduates deeper towards the center. This could be due to weathering/erosion.

FossilDAWG Posted February 16, 2021 Share Posted February 16, 2021 I think it is the impression of a small favositid coral colony. The original colony was dome-shaped, and so the impression appears as a depression, with the "tubes" being the interior of the individual corallites.

Rockwood Posted February 16, 2021 Share Posted February 16, 2021 I bet there wasn't a superstore in sight. It's a good idea to have a second spare tire and plenty of gas with you up that far. I agree that it is a fine, if inverted, example of a favositid coral head. It is primarily a weathered mold at this point. Most likely it was exposed to erosion by glaciers thousands of years ago. 2 Link to comment Share on other sites More sharing options...
IsaacTheFossilMan Posted February 16, 2021 Share Posted February 16, 2021 I agree with Rockwood. ~ Isaac; www.isaactfm.com "Don't move!

MainefossilRocks Posted February 16, 2021 Author Share Posted February 16, 2021 Thanks for the ID. I see a photo at this link of a coral of the sort you mention - https://louisvillefossils.blogspot.com/2015/11/favosites-coral-fossil.html which looks like it would leave such an impression 2 Link to comment Share on other sites More sharing options...
abyssunder Posted February 16, 2021 Share Posted February 16, 2021 It reminds me of tabulate corals like Pleurodictyum, characterized by polygonal corallites. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Pleurodictyum was my first impression as well. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rockwood Posted February 16, 2021 Share Posted February 16, 2021 I'm not convinced the resolution needed to make the distinction between regular and irregular polygons is available. Link to comment Share on other sites More sharing options...
