Kane Posted March 23, 2021 Share Posted March 23, 2021 Some interesting finds in the field today, but this one made me wonder if this was a brachidium or some other related feature. It looks like a trilobite, so naturally I picked it up. The piece was long exposed to the elements. Length: ~3cm Age: Mid-Devonian (Dundee Fm, Ontario, Canada). ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted March 23, 2021 Share Posted March 23, 2021 Don't think it's a brachiopod bit. Looks a bit like a 'cystoid' to me. 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Kane Posted March 23, 2021 Author Share Posted March 23, 2021 Hm... A cystoid would be an unexpected and lovely surprise! I should provide a few better photos now that I'm home. In the darker of the two, you can see why I took it for a distorted/disarticulated trilobite! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Rockwood Posted March 23, 2021 Share Posted March 23, 2021 I agree with the echinoderm angle. Maybe one of the more unusually shaped crinoids such as Ammonicrinus ? It's listed as mid Devonian. Link to comment Share on other sites More sharing options...

Top Trilo Posted March 23, 2021 Share Posted March 23, 2021 Is there any chance of further prepping it? “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

Al Dente Posted March 23, 2021 Share Posted March 23, 2021 Here’s what I see. Blue is the cephalon, yellow the pygidium, red the axis and green is lateral pleurae. 2 2 Link to comment Share on other sites More sharing options...
Rockwood Posted March 23, 2021 Share Posted March 23, 2021 Some of the blue originally extended to overlap the green ? Seen in a faint sectioning to the lower. Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 23, 2021 Share Posted March 23, 2021 Kane is the trilobite whisperer of course, so I would expect him to instantly recognize a trilobite even if crushed or fragmentary. That being said it looks like a trilobite to me also. Don Link to comment Share on other sites More sharing options...
Kane Posted March 24, 2021 Author Share Posted March 24, 2021 Thanks, all! I suspected it might be, but second guessed myself (but brought it home just in case). But perhaps my hope turns out to be true. I’ll see if I can prep it a bit tomorrow, or what is left of it, and see if it is a match for one of three species it might be, out of the seven I’ve so far recorded in this facies. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Kane Posted March 24, 2021 Author Share Posted March 24, 2021 After some preliminary scribing, I can happily confirm it is a trilobite. This would be a Pseudodechenella sp. Despite its broken back, what is remarkable is in finding one nearly complete in this material -- known for having nothing but moulted or tidally disarticulated fragments. Given its state, this will not be the most fun prep in the world. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Top Trilo Posted March 24, 2021 Share Posted March 24, 2021 Mystery is solved! I think the difficulty was the fact it was disarticulated and that Kane wasn't sure it was a trilobite, not many would argue with that “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.
