fossil ID

lol, well I can ask her.
It's not a big deal, I just thought it would be fun to try and guess what it was.

thanks for the offer of help

Hey, she emailed me and said she will send it to you!

And thanks, Larry, and everyone, for your help.

Hey. I know everyone has been breathless, waiting for me to identify that fossil.

But, I have never received it. Did the owner mail it to me? I hope not, because it must be lost.

I'd still be glad to try to identify it, if she wants to send it to me. I'll mail it back in a week, or ten days.

I sent a link to this thread to Dr. Michael Gibson, an invertebrate paleontologist at UT Martin. Here is his reply:

Nice trace! I have not seen that one before, but the change in morphology and direction indicates a behavioral change in the trace maker. We are probably looking at several traces that are all added together in a series (really cool)! It definitely is not bryozoan, etc. as the blog was musing. The bulbous end is likely the resting trace. The crescent shaped parts indicated movement and are similar to a trace called Scalarituba (but this isn't that trace). The vertical component is clearly a non-feeding locomotion trace. The angle of change suggests it hunkered down in a spot (resting?) and then proceeded again. I will poke through my trace fossil monographs and see what I can find.
