This Mazon Creek nodule arrived for me today. Label said : Polychaete worm - Astreptoscolex anasilosus Had a look in my copy of Wittry and it doesn’t quite seem to match. Thoughts ?

Here are a couple pieces that I want to post to see what others think @RCFossils @Mark Kmiecik @stats @deutscheben @connorp This first piece, I think might be a G. Greenei. This next piece may be a “blade”, Esconichthys apopyris. And lastly, 2 worms.

Here are two new Mazon Creek finds I'm not positive on. This first one looks very familiar but I can't place it. The second is a nice 3D piece of wood. My best guess is a Psaronius stem (tree fern), but I haven't found anything like this before so I was hoping for a second opinion. @Nimravis @stats @Mark Kmiecik @deutscheben @RCFossils I appreciate any help.

I am thinking that this is an example of Palaeoxyris prendelli, if it is, I believe it is my first of this specific one. @RCFossils @stats

Just came across this piece in a box of loose concretions. It has the look of an insect wing, but believe it might be a Neuropteris inflata leaf. What do you think? @RCFossils @deutscheben @stats @connorp @Mark Kmiecik Sorry for the darker pics, but this is a real black concretion.

I have two odd pieces tonight and was wondering if anyone has an idea. @RCFossils @deutscheben @Mark Kmiecik @stats @connorp This first one it odd looking, I am thinking fauna, but wonder if it is a seed. This next piece reminds me of an insect, but I think it might be a worm.

@RCFossils @Mark Kmiecik @connorp @deutscheben @stats Looking for thoughts on these few pieces- It looks a bit like the barnacle Illilepas damrowi Thinking possible Reticulomedusa greenei This next one is odd looking and the only thing that I can think of is an Octomedusa pieckorum. Lastly, looking for something on this bivalve.

I think it is a long shot, but could this be the Essex crustacean, Dithyrocaris? @RCFossils
