switchedtogeico Posted August 5, 2018 Share Posted August 5, 2018 Hello everyone, I found the following fossils along the cost of Lake Huron in Ontario last weekend, and was hoping I could get some help identifying them. I've tried guessing at what they are, but I'm rather inexperienced with this. I also have no clue as to the time periods, sorry! The first one I assumed was some kind of gastropod Link to comment Share on other sites More sharing options...
switchedtogeico Posted August 5, 2018 Author Share Posted August 5, 2018 The next few I've been unsure about. Perhaps some kind of coral or barnacle fossils? Link to comment Share on other sites More sharing options...
Kane Posted August 5, 2018 Share Posted August 5, 2018 Neat finds. Yes, the first is a gastropod, and the second is rugose coral. Where along Lake Huron? ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Kane Posted August 5, 2018 Share Posted August 5, 2018 Those would also be rugose coral. The septae are clearly visible on these. I would guess these are possibly Devonian in age. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Thanks! I was near the eastern shores, so a little south of Tobermory, near Kincardine Link to comment Share on other sites More sharing options...
Kane Posted August 5, 2018 Share Posted August 5, 2018 That sounds about right for Devonian deposits (Detroit River Group). There are some impressive coral reef fossils up that way. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 5, 2018 Share Posted August 5, 2018 I agree, with Professor Kane, ... Rugose corals, and a nice gastropod steinkern. (A steinkern is a fossil that has formed by sand or mud filling up the inside of a shell and hardening. The shell itself often dissolves away, leaving just the fill behind.)

switchedtogeico Posted August 5, 2018 Author Share Posted August 5, 2018 Not sure if these are considered impressive, but I did in fact find a number of other coral fossils! This was one of the biggest. Link to comment Share on other sites More sharing options...
Kane Posted August 5, 2018 Share Posted August 5, 2018 These would be tabulate (colonial) corals. They can definitely get quite large! ~370 million years ago, that whole area was a coral reef system a bit south of the equator. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Ludwigia Posted August 5, 2018 Share Posted August 5, 2018 That last coral is probably a species of Favosites. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
