Nal Posted September 5, 2017 Share Posted September 5, 2017 I found this specimen on a beach in northern michigan. It was found along with sea shell fossils and petaskys. Link to comment Share on other sites More sharing options...
Kane Posted September 5, 2017 Share Posted September 5, 2017 Welcome to the Forum! It looks to me like you have a rugose coral, somewhat weathered. Your area is certainly Paleozoic in origin, so this is a likely match. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Nal Posted September 5, 2017 Author Share Posted September 5, 2017 Thanks for the welcome and the reponse. I really appreciate it. Would this be considered a fossil? Sorry for beginner questions. Thanks again Link to comment Share on other sites More sharing options...
FossilDudeCO Posted September 5, 2017 Share Posted September 5, 2017 Kane is all over this one! I think he is correct with a very weathered Rugose horn coral. Yes it would be a fossil and would be several million years old Link to comment Share on other sites More sharing options...
Kane Posted September 5, 2017 Share Posted September 5, 2017 It is a fossil! I would place it somewhere in the Devonian given your location, but I may be wrong (Michigan is a big place!).

Nal Posted September 5, 2017 Author Share Posted September 5, 2017 Thanks for the map. Very interesting. For scale, the fossil is 1.5 inches in diameter and 2.25 inches long. Link to comment Share on other sites More sharing options...
JohnBrewer Posted September 5, 2017 Share Posted September 5, 2017 Welcome to the forum Nal. Rugose for me too. I love the shape it's been given by the sea. Nice find. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Nal Posted September 5, 2017 Author Share Posted September 5, 2017 It ws found close to traverse city. So devonian is spot on. The diversity of the rocks found on the beaches the area is astounding.

Nal Posted September 5, 2017 Author Share Posted September 5, 2017 Is there any chance this is a huronia annulata? Link to comment Share on other sites More sharing options...
FossilDAWG Posted September 5, 2017 Share Posted September 5, 2017 I have to respectfully disagree with the ID of a rugose coral. The interior shows no structures resembling septa, tabulae, dissepiments, etc that would be expected of a coral. Rather, the fossil seems to me to be a portion of the siphuncle of an actinocerid nautiloid; Huronia is a likely candidate. Don C 4 Link to comment Share on other sites More sharing options...
Nal Posted September 5, 2017 Author Share Posted September 5, 2017 It seems to resemble the pictures on page 6. And yes, it seems as if my journey is just beginning. My three year old son is in awe of the fossils we found. 1 Link to comment Share on other sites More sharing options...

Basing on the pictures, I suppose I assumed the appearance of septae in this piece. Good catch, Don! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Kane Posted September 5, 2017 Share Posted September 5, 2017 I am going to agree with @FossilDAWG that this is a piece of Huronia. The big annulations are a big tip-off (although, in my defense, I've seen some rugose that have been very weathered showing similar appearance - and you did say it was a beach find!). ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

abyssunder Posted September 6, 2017 Share Posted September 6, 2017 (edited) Pickin' up the pieces, no doubt, it has a close resemblance to Huronia, and H. vertebralis. buoyancy-controlling tubes in cephalopods. Little is known about their outer shells, but, in general, they were probably about twice the diameter of these tubes. Some specimens have been reported about 5 or 6 feet long. - to complete the missing part of the text Edited September 7, 2017 by abyssunder " 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.

Huronia is a Silurian species right?
