I looked at some more references this morning and now I’m leaning more towards Esconites. Its tricky!

Yes identification of worms, especially ones not exceptionally preserved, can be kind of tricky.

I'll pull out my microscope short to look at the details a little closer.

 

I do believe this one is Esconites though.

Had this piece open up today, maybe a coprolite. Anyone agree or disagree?

Also had a small bivalve open but it’s hard to photograph

I'm leaning towards it being a coprolite. Is it about 2 to 2-1/2 inches long?

Fossil hunting is easy -- they don't run away when you shoot at them!

Sorry forgot measurements. Yes it is 2 inches exact.

Recently received a ton of Mazon creek fossils as a gift from a family friend that use to hunt for them back in the 80’s to eary 2000’s. Was mostly jellyfish but thought to share some of the interesting pieces.

 

Looks like all the flora pieces were collected in the actual Mazon creek. Some of them are quite large and if anyone can help with ID, that would be appreciated:

 

The other half for this one is more complete but is missing the very tip. Have it currently tucked away.

Also included about 5 totes as well full of concretions. It was almost entirely jellyfish but included a couple worms, coprolite, sea cucumber. Here are some of the really interesting associated pieces:

 

I count 10+ jellyfish on this one

Catching up on 2 trips I made this spring.  These first set of pictures are from Pit 11 back in March:

My coolest find so far from this trip was the back half of an exposed Tully Monster

Of the ones I brought home, I cracked open maybe 20 Essexella. Here are a couple of my favorites:

Also made a trip to the Braceville spoil pile this year, these are my up-to-date finds but I will try to keep updates as more crack open:

 

1637817352_image5(2).thumb.jpeg.bd6d89080744b38c4cf86f03cf28eca4.jpeg

 

This first one, I am unsure what it is.  Does anyone have a clue?  I was thinking maybe a seed but I do not see much structure within it.

Nice finds, a piece of Tully is always exciting! 

 

I would identify your first Braceville find as a small Essexella.

Thank you!  Must have been a tiny one then, it's less than a cm in diameter

Some from the Braceville Pile that have opened:

 

Essexella:

Heres a cool Mazonomya with a blue preservation:

I’m guessing a Mazopherusa prinosi (fan worm):

Here are a couple of my recent favorites to open up from the Braceville pile. I’ll continue to add additional pieces that have opened:


Esconites:

Couple worms that have opened recently:

 

I’m guessing some type of worm associated with a coprolite:

IMG_5637.thumb.jpeg.6b268f1886a335510dcf178ac0abb4ed.jpeg

 

Unknown, any suggestions on if identifiable?

IMG_5638.thumb.jpeg.8bc43117e617409ed5f2f579a39f1c2e.jpeg

 

Likewise unsure if identifiable. Second one poorly preserved on the back that I might be able to clean up:

If these are all from Braceville, based on the appearance I would say the first is a sea cucumber Achistrum sp., while the remaining worms are the fan worm Mazopherusa prinosi.

Great thanks! Yep all from braceville. How can you tell they’re the fan worm if they don’t have bristles preserved?

The second specimen actually does show a faint little bit of the fan at the top left(middle), but the blotchy dark spots and type of segmentation and smooth margins are also typical of fan worms from there. 
(Although re-examining your last specimen it does seem to have parapodia extending from the segments which would actually make it less likely it is Mazopherusa- it might be clearer with a little cleaning, but I may have been wrong about that one)

 

Finally, fan worms are the most frequently encountered worms from the Braceville location by far- so much so that I have seen it referred to as “Fan Worm Hill”.

Interesting thanks for the help! I’ll look a little more into the first one. Was looking back at this worm I opened about a month ago that I called a fan worm but looking at your description, it doesn’t seem to fit. Unsure what this one could be but there’s no segmentation or jaw parts to it.

Here's a couple new pieces.

 

First one I am thinking another Achistrum?
