Some different views of specimen above. These are from the Devonian of ohio. Personally collected. Very rare. Several are now in museum collections.

Very cool! I’m not used to seeing any crustaceans from the Devonian, heck, sometimes I have trouble finding an arthropod or two!

Happy hunting,

Specimens from concretions in NE Ohio whether phylocarids or Paleopalaemon can be difficult to photograph since they are preserved 3 dimensionally. There is a nice abdomen and tail that wraps all the way around. I probably should add some more pics.

Please do, and if You can point out what is which - that would help, those that never seen one before (like Me).

These are amazing. I have never seen these before. 

Thanks for posting them. :)

Ditto that!

I am amazed by this creature, of whose existence I was unaware. What a great surprise, and what splendid examples! :wub:

Thank you everyone.  I only picked up paleontology as a hobby when I turned 50, just 5 years ago. These specimens have given me a fortunate and unique opportunity to participate in the long overdue update regarding Palaeopalaemon recently completed. Very few people realize that decapods had already evolved into a very modern form in the Devonian but did not radiate unil far more recently. I am coauthor. Please see attached. I have attached as a courtesy. The 5 specimens I contributed now will reside in the Smithsonian collections which to me is worth more than any $$$.

Thank you and glad to share.

 

Since you are a coelacanth guy, you will love this ,but unbeknownst to me until I just recently happened to have an expert identify them, I have in my possession two juvenile Chagrinia specimens. They are very disarticulated and in small concretions that I had been prepping casually for  several years. The holotype is at CMNH and was collected in 1960. They (scales) can only be appreciated under a microscope.

That sounds amazing!  And rare! 

I'll have to look into those.

No chance of any pics of these, I take it?

I am gong to try taking some macro pics within the next week. But again, very dis-articulated. I have always referred to them as looking like Devonian seagull puke...

 Amazing finds. 

 

If you collected some of the decopods and donated them to the Smithsonian you are eligible for the Partners Award. You should post this fact into TFF Partners in Paleontology section. http://www.thefossilforum.com/index.php?/forum/188-partners-in-paleontology-member-contributions-to-science/

My goal is to leave no stone or fossil unturned.

Thanks,  but I contributed them to the project and study. And since specimens used in a professional publication must be permanently stored in a public collection Dr. Feldmann felt it best to direct them to the Smithsonian. Not sure if that makes a difference. Either way I have all documentation. Marc

Wonderful specimens of a unique early decapod. :wub:

And thanks for donating them to the Smithsonian and your contributions to the paper.

The "partners in paleontology" is a TFF award for members that have donated a fossil find to a university or museum.

You only need to make a post that details the donation in the correct thread (linked in DPSammonite's post above), to collect Your prestigious badge.
