Monica Posted January 15, 2019 Share Posted January 15, 2019 Hi all! While I was looking through some of my fossils, I came across the specimen below, and I think it's a new little coral for me! Does anyone have an idea as to its identity? It appears to be a tabulate coral, but if anyone could let me know its genus and species then I'd be much obliged! It's from Hungry Hollow near Arkona, Ontario, Canada (mid-Devonian in age). Thanks in advance for your help! Monica 1 Link to comment Share on other sites More sharing options...

Thecosmilia Trichitoma Posted January 15, 2019 Share Posted January 15, 2019 It looks like a coral from the genus Pleurodictyum IMO. 1 It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt -Mark Twain Link to comment Share on other sites More sharing options...

Al Tahan Posted January 15, 2019 Share Posted January 15, 2019 @Kane will know for certain but it’s probably as stated above...Pleurodictyum....but it does look kinda different. I’ll sit and wait 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 15, 2019 Share Posted January 15, 2019 Yes, Plaurodictyum, I think. Pleaurodictyum americanum? Very nice! 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Wrangellian Posted January 15, 2019 Share Posted January 15, 2019 Can't help either, but nice whatever it is. Lots of things going on on that piece. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted January 15, 2019 Share Posted January 15, 2019 I'm thinking it looks like a type of Favosites. F.nitella or F. alveola? 6 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Monica Posted January 15, 2019 Author Share Posted January 15, 2019 Thanks for responding, everyone! Because the specimen in question appears not to be exactly spherical (you can see a little bit branching off of the spherical part near the bottom of the picture), I'm leaning towards what Roger has stated - perhaps it's a new Favosites for me - perhaps F. nitella (although it would be great if it were a Pleurodictyum since I don't have that genus yet! ). I'll take a few more pictures tonight from different angles to see if a more certain ID can be nailed down. I'll also take a picture of the other item located above the coral in question - perhaps you can help me identify that one, too! Link to comment Share on other sites More sharing options...
Kane Posted January 15, 2019 Share Posted January 15, 2019 I like the sound of Favosites (possibly a small bit of F. alpenensis? -- but more likely closer to Ludwigia's guess of F. nitella). @middevonian has put in a lot more time than most with the corals at that site, so hopefully he can weigh in as well. I can also see if I have any similar ones left on hand to compare, as I've been downsizing the Arkona stuff and getting rid of a lot of the coral that I collected some years ago. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Northern Sharks Posted January 15, 2019 Share Posted January 15, 2019 I'm not sure of the correct ID, but I can say that, of all the corals at HH (and there are plenty of them), Pleurodictyum is one of, if not THE rarest. 2 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
erose Posted January 15, 2019 Share Posted January 15, 2019 I am also going to chime in with my two cents. Coralites seem small for Pleurodictyum and as stated above the overall shape is not as hemispherical as one would expect for Pleurodictyum. I am not familiar with the Hungry Hollow fauna, but I know that in the New York Middle Devonian there are numerous species of Favosites. My money is on that genus. Oh yes, nice specimen, too. 1 Link to comment Share on other sites More sharing options...
Malcolmt Posted January 15, 2019 Share Posted January 15, 2019 I have never found a Pleurodictyum at Arkona but it could be, looks similar and they have been found there in the past. This could be a broken fragment that has been flattend 3 Link to comment Share on other sites More sharing options...

Guest11596 Posted January 16, 2019 Share Posted January 16, 2019 Hi Monica, I believe the first coral is a piece of Favosites arbuscula. The second appears to be Cladopora. Best, Darrell 2 Link to comment Share on other sites More sharing options...

PyritizeMe Posted January 17, 2019 Share Posted January 17, 2019 In the first picture of the other angle pictures I see what seems to be a Cephalopod fossil , around 5 o clock , it looks like chambers and waves like a Goniatite? 1 Link to comment Share on other sites More sharing options...

Good eye! I didn't even notice that!!! I'll have a closer look and perhaps try to get some of the matrix off and let you know what I find... Thanks so much for the input!

Monica Posted January 26, 2019 Author Share Posted January 26, 2019 Hello again! After examining this piece a little more closely, I found another interesting tidbit on the rock that I think is likely part of a coral, but it kind of looks like a small crinoid calyx (it's about 5mm in diameter) - please see pictures below: What do you think? Thanks once again! Monica Link to comment Share on other sites More sharing options...
