ChrisBCritters Posted February 8, 2021 Share Posted February 8, 2021 (edited) I'm looking for assistance identifying a large fossil that was in with skids of limestone rockery from the Niagara Escarpment. I have uploaded a series of pictures to Flickr https://flic.kr/s/aHsmTVvrFN and attached one image. It looks like a type of coral. There is lots of texture on the surface. When opened up, it is full of long columns. Thanks. Edited February 8, 2021 by ChrisBCritters Link to comment Share on other sites More sharing options...
Coco Posted February 8, 2021 Share Posted February 8, 2021 Hi, I don’t know if it’s a fossil, but it looks like it’s made of aragonite. Please put your photos directly on the forum, don't require members to leave to go see them elsewhere, you will have little visibility and your link is not permanent.

I could only find one picture that fit within the download limit. The others were 7MB in size. I will try to shrink them. Link to comment Share on other sites More sharing options...

Thomas.Dodson Posted February 8, 2021 Share Posted February 8, 2021 I agree with Favosites. Favosites favosus is reported from the Silurian Lockport Formation (the formation that makes up the outcrops of the Niagaran Escarpment) at Lake Timiskaming. In fact, it is within the Favosites favosus zone. "The Favosites favosus zone marks the Cordell dolomite in Michigan (MM) and Wisconsin (MW), the Hopkinton dolomite in Iowa (HOP),the Fossil Hill formation in Manitoulin Island and the Bruce Peninsula (FH), and the Lockport formation at Lake Timiskaming (LT) (called the Thornloe limestone by Flower, 1946, p. 519). The widespread coral beds in this area carry the following typical fauna: Favosites favosus (Goldfuss) - Hop, MW, MM, FH, LT. Arachnophyllum pentagonum (Goldfuss) - Hop, MW, MM, FH, LT. A. striatum (d'orbigny) - Hop, MM, FH. Romingerella major (Rominger) [ = Thecia major] - MM, FH. Coenites crassus (Rominger) - MM, FH, LT. Halysites labyrinthicus (Goldfuss) - MW, MM, LT. Ptychophyllum stokesi Edwards & Haime - MM, FH. Stokesoceras romingeri Foerste - MM, LT. Huronia vertebralis Stokes - HOD.MM. FH." -SILURIAN ROCKS OF MICHIGAN AND THEIR CORRELATION, George M.

FossilDAWG Posted February 8, 2021 Share Posted February 8, 2021 These are all favositid corals, as has been stated already. However there is more than one species of Favosites in the Lockport, the Cordell, and in equivalent strata at Lake Temiskaming. It could be useful to have an indication of scale in the images with the close-ups of the corallites as corallite diameter is one useful diagnostic character (though not the only one).

In fact, it is within the Favosites favosus zone. It probably is unlikely these are coming from Lake Timiskaming as that is quite a long haul for rock! It is more likely coming from anywhere along the escarpment band that has active quarries, from Bruce Peninsula down to Niagara region. The escarpment itself is certainly more diverse in its stratigraphic range than simply the Lockport or Amabel dolomite, so one cannot entirely rule out a non-Lockport Fm source. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted February 8, 2021 Share Posted February 8, 2021 They way I phrased it might have been misleading. I just meant to mention that it is reported from the Lockport Formation and the Lockport is in the Favosites favosus zone. I wasn't trying to suggest that they came from Lake Timiskaming or it was definitely Favosites favosus. It's simply that the paper specifically lists corals from Lake Timiskaming for Lockport Formation fossils which is why I mentioned the locality. The paper also mentions that there are additional coral species not limited to that zone but occur across others. 17 minutes ago, Kane said: The escarpment itself is certainly more diverse in its stratigraphic range than simply the Lockport or Amabel dolomite, so one cannot entirely rule out a non-Lockport Fm source. I wasn't aware of this but I'm not surprised. @ChrisBCritters, can we get a more specific locality to try and narrow down a Formation? Link to comment Share on other sites More sharing options...
