Help With Ordovician Carpoid From Iowa


RCFossils

Recommended Posts

I am hoping someone on the forum is familiar with Ordovician carpoids.

i collected this specimen at a roadcut in Claremont Iowa.

it is from the Maquoketa Formation.

Any information on what species it might be would be greatly appreciated.

Now that's something you don't see every day. Nice find but I can't help with I'd. 

Agreed, quite fascinating and it's incredibly well preserved for being from the Ordovician!

Maybe @crinus can have a look. 

He knows his stuff.

there is no Maquoketa Formation in Ohio. There might be an equivalent age formation but I do not know which one it would be. (possibly the Whitewater) The carpoid looks like the tail of an Enoploura popeii possibly

Thanks everyone for your help with the ID.

I agree that it appears to be similar to Scalenocystites.

The only difference that I can detect from the figured specimen is that mine appears to have horn like spines where the body meets the arm. I will upload a few more pictures.

I have always been fascinated by these bizarre creatures and i am thrilled to have finally found one.

Thanks for the correction. As the title indicated, this was found in Iowa (not Ohio).

Mind-blowing that this is from 488 million years ago (Unless this newbie is mistaken.), and yet is so well preserved. I have never seen anything like it. What a strange creature, from our early world which was inhabited by nothing but strange creatures. Congratulations on your cool find.

I suggest a careful lecture of(4.22Mb):

(betting that it is simply to be found in Fruitbat's library)

Fleur Noailles' piece in Czech Bulletin of Geosciences 89/3-2014 is informative as well.

The "tail" is, taxonomically speaking,the least interesting part

Welcome to the Forum.

If you read the thread you will see that the typo in the first post has already been corrected several times.
