Dicranurus Posted May 5, 2009 Share Posted May 5, 2009 What is this weird fossil? Naraoia? Upper Middle Cambrian, Weeks formation, Millard County, Utah, USA.

jpbowden Posted May 5, 2009 Share Posted May 5, 2009 Fantastic, I have never seen anything like it. Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted May 5, 2009 Share Posted May 5, 2009 It looks like a trilobite under there, but needs cleaning. Might be a rarer type from that formation so be careful. Link to comment Share on other sites More sharing options...
Dicranurus Posted May 6, 2009 Author Share Posted May 6, 2009 It looks like a trilobite under there, but needs cleaning. Might be a rarer type from that formation so be careful. Thanks. First I think it soft-bodied Arthropod, but it is only educated guess.

RJB Posted May 6, 2009 Share Posted May 6, 2009 I just wish I could see it. RB Link to comment Share on other sites More sharing options...
Dicranurus Posted May 6, 2009 Author Share Posted May 6, 2009 I just wish I could see it.RB Here is another (fixed) photo. There is a couple details, for example dark "ribs".

mommabetts Posted May 6, 2009 Share Posted May 6, 2009 Can't wait to see it prepped. Link to comment Share on other sites More sharing options...
ebrocklds Posted May 6, 2009 Share Posted May 6, 2009 DON'T DO ANY PREP, YOU WILL ONLY RUIN IT!!!!!! these fossils are of soft bodies animals and are a thin film on the surface of the rock. this is definately some type of soft bodied material. it is similar to but not exactly like emeradella. check out this link to see some other soft bodied animals from the weeks formaiton. http://www.fossilmall.com/EDCOPE_Enterpris...t-Fossils-1.htm also look here http://weekstrilobites.com/weekstrilobites.htm very nice fossil.

Brock Thanks. I won't prep this specimen. I know this is (rare) soft bodies animal and extra prep will probably only ruin it.

Ebo Posted May 14, 2009 Share Posted May 14, 2009 Didranurus there are plenty of soft-body un-described arthropods coming form the Weeks Formation. This understudied (unfortunately) mid Cambrian lagerstätten has yielded an extremely rich association of unique trilobites (you can take a look at my web site: http://www.keyobs.be/fr/ebonino/html/weeks_trilobites_1.html ) and soft body organisms. Your specimens can be an opistosoma (thorax) of an aglaspidid-like arthropod (like Beckwithia typa), the head and the tail are missed or (the prosoma -the cephalon) under the body of this incomplete specimens. Examples of Aglaspidid can be found here: http://www.keyobs.be/fr/ebonino/html/aglaspidi.html Take your specimen in a good place because it will be more and more difficult to find specimens coming from this recently closed site.

Frank Menser Posted May 14, 2009 Share Posted May 14, 2009 It looks very much like a Trilobite to me which does make it a difficult decision. If it is a soft bodied species (and possibly something new) you don't want to mess with it. However, if it is a trilobite (and possibly a new species) then you need to expose more. (I should have these problems). Perhaps it might be worth your while to get it Xrayed. Maybe that will supply the essential details without risking the piece. Be true to the reality you create.

Ebo Thanks Ebo, My specimen will be in a good place. I agreed that this can be aglaspidid-like arthropod. Frank Menser I think this an soft bodies arthropod. I don't believe that this is a trilobite. I don't have enough experience of prepping these kind of fossils, so I won't do anything to this specimen, because I don't want to destroy this specimen.

New Members neutrinoboy Posted May 15, 2009 New Members Share Posted May 15, 2009 I've seen several of these animals over the years. There are several arthropods with a similar appearance, but I beleive this is a aglaspid very similar to Beckwithia typa. It has a thinner shell, but in appearance is almost exactly the same. It's possible specimens like this are in fact Beckwithia typa, but just not as well preserved. My guess is that its a different species however. This one is enrolled and about average quality.
