Innocentx Posted December 14, 2016 Share Posted December 14, 2016 This is from the Wabaunsee Group (Phanerozoic | Paleozoic | Carboniferous Pennsylvanian-Late [Virgilian]) Includes: Wood Siding FM, Root Shale, Stotler Limestone (base ST), Pillsbury Shale, Zeandale Limestone (base Z), Willard Shale, Emporia Limestone (base E), Auburn Shale, Bern Limestone (base BR), Scranton Shale, Howard Limestone (base H), and Severy Shale. Found these unknown objects attached to the interior of a myalina clam shell. This is a marine environment but I'm not sure which layer of the Wabaunsee Group this is from. I've never seen this before so would appreciate any help with ID. I'd be happy to furnish more photos of layer and fossil.

Innocentx Posted December 14, 2016 Author Share Posted December 14, 2016 (edited) Herb, they seem rather elaborate for worm tubes. Can you post photo of similar, please? Also, I have never seen worm burrows that were laid down on the surface of a shell.

abyssunder Posted December 14, 2016 Share Posted December 14, 2016 I see Spreiten there connected with, also, U shaped crosslines. Looks similar to Rhizocorallium . 6 " 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.

Pemphix Posted December 15, 2016 Share Posted December 15, 2016 +1 more for trace-fossil. Spreitenbau (following SEILACHER) and Rhizocorallium seems to be fine in an first attempt. Maybe special name for this formation and location. Nice find ! Never seen this on a shell, too.... 1 Link to comment Share on other sites More sharing options...
Plax Posted December 15, 2016 Share Posted December 15, 2016 thanks for the enlightenment Abyssunder! I thought these were much bigger traces and took the ones attached to the shells in the pics as worm tubes. Link to comment Share on other sites More sharing options...
westcoast Posted December 15, 2016 Share Posted December 15, 2016 Certainly looks like Rhizocorallium however I have never seen one attached to shell like that. It would be good to see the other side of the shell to see if it has been bored through. Really nice find! Link to comment Share on other sites More sharing options...
Innocentx Posted December 15, 2016 Author Share Posted December 15, 2016 Thanks to all, and I do feel welcome here. The location, surface of the shell, had thrown me off. "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Drizzt0000 Posted January 2, 2017 Share Posted January 2, 2017 Looks like a trace fossil. I have a large one I posted on here along time ago so...I'm for trace fossil too Link to comment Share on other sites More sharing options...
abyssunder Posted May 27, 2017 Share Posted May 27, 2017 Accidentally I've found these little ones in my research for other goodies. The resemblance would be excellent although the geological time is fairly different, but I think that couldn't be a problem. They look appropriate to the specimens in question.

Innocentx Posted May 28, 2017 Author Share Posted May 28, 2017 Oh. that is so cool and so small. Yes, different time period but life repeats forms down through time which is an amazing feature!

abyssunder Posted May 28, 2017 Share Posted May 28, 2017 I totally agree with you, especially after I checked the possibility of 'Caulostrepsis in Myalina shell'. And bingo! - A. Seilacher. 1969. Paleoecology of Boring Barnacles. Am. Zoologist, 9: 705-719. Once again the eminent Seilacher...

Innocentx Posted May 30, 2017 Author Share Posted May 30, 2017 I appreciate your renewed interest in this fossil. Because of this I've done more research and learned more. Even though the internet is an unparalleled resource, there often remain questions. The forensic aspects of paleontology, the mystery to be solved, is what maintains interest. The ichnofacies are complicated subject. Of many theories, one says they are independant of geological time periods, and are indicators of conditions. Mostly what I know is I enjoy seeing them, wondering about creature that did them, so I'm easily amused by all the fossils I find. I will have to get my better magnifyer out and check for small marks on the drilled holes.
