pleecan Posted October 25, 2010 Share Posted October 25, 2010 (edited) This is lower Silurian in the layers above Queenston Shale Formation. I know that soft tissue does not usually fossilize.... but Do you see worm cuticle? Opinions? Could this be a worm / annelid? size 10mm Edited October 25, 2010 by pleecan Link to comment Share on other sites More sharing options...
jpc Posted October 25, 2010 Share Posted October 25, 2010 Hmmmm.... no, I see a black something, but I have a hard time making it anything wormy. Link to comment Share on other sites More sharing options...
Mr. Edonihce Posted October 25, 2010 Share Posted October 25, 2010 This is lower Silurian in the layers above Queenston Shale Formation. I know that soft tissue does not usually fossilize.... but Do you see worm cuticle? Opinions? Could this be a worm / annelid? size 10mm Well, I do see what you mean, from a commoner's standpoint (i.e. mine), but I have no idea what a Silurian worm should even look like. So, I certainly can't say anything helpful. Good luck. . ____________________ scale in avatar is millimeters ____________________ Come visit Sandi, the 'Fossil Journey Cruiser' ____________________ WIPS (the Western Interior Paleontological Society - http://www.westernpaleo.org) ____________________ "Being genetically cursed with an almost inhuman sense of curiosity and wonder, I'm hard-wired to investigate even the most unlikely, uninteresting (to others anyway) and irrelevant details; often asking hypothetical questions from many angles in an attempt to understand something more thoroughly." -- Mr. Edonihce Link to comment Share on other sites More sharing options...
paleobarbie Posted October 25, 2010 Share Posted October 25, 2010 Not likely because: 1) As you mentioned, soft tissue does not preserve well 2) The matrix looks like silicate. If so, the likelihood of it being an annelid is very slim. It is pretty cool, though. Link to comment Share on other sites More sharing options...

I believe the material comes from Clinton and Cataract Groups which include sandstone dolostone and shale layers, early Silurian. JPC and Edonihce, thank for your replies.

JimB88 Posted October 25, 2010 Share Posted October 25, 2010 this is a silurian a leech-like critter (which the segments in yours reminded me of) though this was preserved in shale. (Racine Formation) Link to comment Share on other sites More sharing options...
pleecan Posted October 26, 2010 Author Share Posted October 26, 2010 Thanks Jim for the pic of leach ... worms have a distinct cuticle pattern... here is an example of Cambrian worm from my collection: Chengjian Cambrian Annelid: Palaeoscolex Link to comment Share on other sites More sharing options...
Mr. Edonihce Posted October 26, 2010 Share Posted October 26, 2010 Now I totally see why you made the connection.....who knows? . ____________________ scale in avatar is millimeters ____________________ Come visit Sandi, the 'Fossil Journey Cruiser' ____________________ WIPS (the Western Interior Paleontological Society - http://www.westernpaleo.org) ____________________ "Being genetically cursed with an almost inhuman sense of curiosity and wonder, I'm hard-wired to investigate even the most unlikely, uninteresting (to others anyway) and irrelevant details; often asking hypothetical questions from many angles in an attempt to understand something more thoroughly." -- Mr. Edonihce Link to comment Share on other sites More sharing options...
