fig rocks Posted June 27, 2009 Share Posted June 27, 2009 This plate is 7" x 8" and the fossil imprint is about 5" x 6 1/2" across. It's from the badlands, but I found it in a box! Link to comment Share on other sites More sharing options...

Auspex Posted June 27, 2009 Share Posted June 27, 2009 I don't get a reading on anything starfish-like... If you mean the long, crossing "welts", those look like "worm" trails to me.

Shamalama Posted June 28, 2009 Share Posted June 28, 2009 If it were a starfish then it would have five fold symmetry and thus five arms. I see only four possible appendages and they are at 90 degree angles to each other. I would agree with Mike and say some sort of concretion or sedimentary structure due to fracturing. I've seen similar stuff from sandy strata that have some areas impregnated with Iron, your looks similar (rusty colored). -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Auspex Posted June 28, 2009 Share Posted June 28, 2009 I think it's an ichnofossil, a trackway. Look at the detail I've enlarged: the "welt" is irregularly "rutted".

Nicholas Posted June 28, 2009 Share Posted June 28, 2009 I think Auspex is correct. The close up shows ridges which resemble burrows. Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 28, 2009 Share Posted June 28, 2009 I agree, ichnofossil. Now this is a starfish: http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

I would agree 99.9% percent of the time.....but there is always that .1% oddity in this world. Brian Evans For every complex problem, there is a solution that is simple, neat, and wrong.

Now that you point that out, I agree, Some sort of trackway does make sense. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

I was wrong.... how the heck did that thing even get fossilized?!? The odds have to be pretty high, have others been found like that in the same location? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
