John K Posted September 9, 2009 Share Posted September 9, 2009 (edited) The last of our Mazon Creek nodules are opening up (great rejoicing..... yeah......)We got mostly jellies, but the last few have been "interesting."I'm pretty sure this guy is a shrimp: Edited March 7, 2014 by John K Link to comment Share on other sites More sharing options...
Auspex Posted September 9, 2009 Share Posted September 9, 2009 I could see it... A little unusual at the edge of the concretion; does the counterpart add any details?

Nicholas Posted September 9, 2009 Share Posted September 9, 2009 I could see it... A little unusual at the edge of the concretion; does the counterpart add any details? I'd like to see the other half as well.. I do however think you may be on to something, a greyscaled picture may show more detail as well. Link to comment Share on other sites More sharing options...
MOROPUS Posted September 9, 2009 Share Posted September 9, 2009 Mmmmmm! not sure if it is a fossil! Normally , concretions grow AROUND an object (in this case, the shrimp)... The only thing it could happen is that the shrimp was fixed later than the center? Link to comment Share on other sites More sharing options...
John K Posted September 9, 2009 Author Share Posted September 9, 2009 (edited) I re-shot with better light and uploaded the photos I posted last night aboveI agree, most concretions form "around" the animal after death, but I've seen examples where they don't (I think our own RCFossils might have some in his galleries - I'm on dial up so it's hard for me to check right now...) A reprint I have (chapter six of "Evolution of Fossils": "Mazon Creek") suggests that some animals actually moved towards the edge of the nodule during the formation process (a brachiopod leaving a death trail was the example I read) and formation of the nodules was almost immediate."a greyscaled picture may show more detail"brilliant! I popped the contrast just a bit, and put in some "lables"; hopefully you'll see what I'm seeing: Edited March 7, 2014 by John K Link to comment Share on other sites More sharing options...
Auspex Posted September 10, 2009 Share Posted September 10, 2009 Good job with the picture! I'm all-in on your ID now (at least as a "shrimp" in the common vernacular; someone who knows can site it chapter and verse, I'm sure).

Nicholas Posted September 10, 2009 Share Posted September 10, 2009 I'm also all in, I thought the Grey scale would work wonders. Wait does this mean I made a worth while suggestion? Link to comment Share on other sites More sharing options...
RCFossils Posted September 12, 2009 Share Posted September 12, 2009 It is definately a shrimp molt. The species is Belotelson magister. Nice find!!! Link to comment Share on other sites More sharing options...
lawooten Posted September 14, 2009 Share Posted September 14, 2009 John K really nice shrimp and the details are great!!! How about posting the jelly fish too. Please would love to see them. The best days are spent collecting fossils Link to comment Share on other sites More sharing options...
