Lower Silurian or upper Ordivician - found today

Recommended Posts

I researched more and learned I was WAY off in my guess and assumption of this fossil. I'll take this as a learning experience however I am still at a loss. I did learn how to read stratigraphy maps however today! Any help is super appreciated.

#edit: 
These were found north of Caesar's Creek area in Ohio, I think it is lower Sullurian? Barren of rugos coral, gastropods everywhere.

Adding lots more pictures from that day and some I more I took just now, they are deteriorating!

Thank you anyone that can help with identifying this, advice and comments are very welcome.

Your brown items seem to be Isotelus trilobite fragments.
The longer ones are either thoracic pleura segments,  one is possibly a cephalic spine.

The last few images look like mineral staining to me.

The picture with multiple yellow arrows (in situ?)  looks like the items are concretions or nodules of some sort.

I don't believe that isotelus trilobites are a silurian trilobite. Upper ordovician yes. Here in the Toronto area they occur in the upper ordovician georgin bay formation

Isotelus ranges from the Gull River Fm to the Georgian Bay Fm in Ontario.

It sounds like the stratigraphy may be questionable.  :shrug:

Yes, I agree. Thanks so much, super appreciate.

Yes the nodules are in situ, I've never seen them like that before. I've been trying to find places where rapid burial happened and there are 'snapshots'. I think as I keep learning and collecting more things will fall into place for me. While I was collecting the 'brown' one, It had appeared it was wrapping around regolith, so the Isotelus must have been tossed around breaking apart. That threw me off but it makes sense now. Those stormy seas sure would have been a site to see!
