Ramo Posted February 11, 2012 Share Posted February 11, 2012 Well I just got back from my Tulsa Trip, and spent a little time around Keystone Lake. I didn't find much, but here are a few pictures. The ripple marks were impressive, and I did bring home a little crinoid hash plate. I also found these weird "Squiggly" lines that I figure are trace fossils from worms, or something. Some of them look kind of like tracks, but I'm guessing they are from indecisive worms, that started squirming one way, then backed up and started another way, etc. Until they made a little cluster that looks like a track. Does that sound possible, or does someone have a better explaination?

Missourian Posted February 11, 2012 Share Posted February 11, 2012 I guess the critter was probing the mud. Also, I like the context shots of the outcroppings and landscape. And that tree seems to have improvised with its root system around that mass of sandstone. Context is critical. Link to comment Share on other sites More sharing options...

cgodwin37 Posted February 11, 2012 Share Posted February 11, 2012 Most the time the trace you see is just how it should be, not accidental but rather a behavior or strategy (feeding, grazing, escape, etc.) Link to comment Share on other sites More sharing options...
Indy Posted February 11, 2012 Share Posted February 11, 2012 Most the time the trace you see is just how it should be, not accidental but rather a behavior or strategy (feeding, grazing, escape, etc.) I agree. I casually refer to these as "feeding trace burrows" However cgodwin37's description is more accurate (feeding, grazing, escape etc.) The traces that look like little hands...I've always referred to those as digitate feeding structures.
