Trilobite ID


Rockchopper

Recommended Posts

The trilobite is: Comura bultyncki  found in the El Otfal and Tazoulaït formations.

 

This is the paper that described it as a new species:

 

Morzadec, Pierre (2001)
Les Trilobites Asteropyginae du Dévonien de l'Anti-Atlas (Maroc). 
Asteropyginae Trilobites from the Devonian of the Anti-Atlas (Morocco).
Palaeontographica Abt.A, 262:53-85

Piranha's IDs are always correct, but just to be sure you should send that trilobite to me for a closer inspection.  :D

I don't agree, i am the best expert here in the close inspections of trilos.:P

I traded mineral specimens for it.  It has the name of the preparer inscribed on the bottom.

Trilobite is about 7.2 cm long.  Hard to get exact since I'm reluctant to get too close.  Still it appears well prepared and a keeper!

Wow, beautiful specimen.

Does this guy still want to trade against minerals?

Good work! :)

Could use some help identifying this trilobite.

Wow, this trilobite brings back memories. It was not easy free standing the pygidium. A collage from Kodak took a picture of the trilobite and made a 3 foot by 4 foot picture for me which hangs in my office.  GerryKloc-tri-pict.jpg.0f245637f383ee40a345a5444a6ddabe.jpg

Hi Gerry - I was fortunate to procure this from a friend who is more into minerals than fossils.  It is clear that this is an exceptional piece and the work you did on it is outstanding.  Having your name and year scribed on the bottom adds to the provenance.  I'm proud to have it in my collection.  And that's a great picture of you next to it!  I don't suppose you would forward the pix to me.  I would like to show my friend who got the better of that trade!

BTW - at age 71 you would think I've seen everything, then the word pygidium comes along!  So had to look it up and realize how little I know.  Keeps the brain cells alive!

Gerry's prep work is so good, I thought it was fake.

So did i, but i think the fact that it is a species from Morocco helped a little this false idea to pop out in the first place.

I know that the (real) trilos from Morocco can be spectacular and varied, but I was unfamiliar with this one, and it looked too perfect. Then again, fake ones aren't usually so perfect, either.

Ok - I think I'm hooked!  Does anyone recommend a good book on trilobites (with pictures) for a beginner like me?  Would hope it would be current, somewhat technical, and complete.

 

thanks in advance

Wow!  22,000+ species!  Thanks for the book referrals.  I'm looking forward to reading more about them.

 

I have one more trilobite I picked up and could use some assistance identifying it so I can properly label it.  Enjoying the responses from everyone.  Got lots to learn.  It's great to have this forum available.

Thanks for the ID.

 

As I understand there are a lot of fakes being offered for sale.  How does one identify the fakes from the real ones?  Certainly there will be some necessary repairs - that I can accept if they are disclosed, but what should one watch out for?

This might be more appropriate to ask in the "real or fakes" section.

Keep looking! They're everywhere!
