Its not a tube though since there are none of the typical markings (seen even is the tube is eroded away). It could the burrow of something that makes a lining, like mucus. That would keep it intact if it were from marine sediment.Kevin Zelniohttps://www.blogger.com/profile/14192385384151149566noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-11905244297833245982007-11-04T01:47:00.000+08:002007-11-04T01:47:00.000+08:00I don't know if it's common but it's certainly pos...I don't know if it's common but it's certainly <A HREF="http://members.aol.com/Waucoba5/ione/trace1.html" REL="nofollow">possible</A>. Say the burrow is in mud and is filled in by sand that gets cemented during diagensis. The shale erodes away leaving behind a cast of the burrow. <BR/><BR/>Steinkern is certainly a possibility although I would expect it to taper in one direction (and perhaps it does I can't quite tell from the picture).Neilhttps://www.blogger.com/profile/10293693723899837239noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-85899707269733157862007-11-02T14:06:00.000+08:002007-11-02T14:06:00.000+08:00Toby - I don't think a coprolite would have that d...Toby - I don't think a coprolite would have that distinctive spiral form.<BR/><BR/>Mike (if that is Mike) and Neil - is it common for fossilised burrows to be dissassociated from their original matrix like that?
