Anomalocaris appendage parts?

[Dave Adams]

Greetings. On 8/6/23 I was out around Pioche, Nevada looking for trilobites. I found a number of specimens and decided on a whim to bring some larger sections of trilobite-bearing shale home for context purposes. After sorting the smaller trilobite samples I sat down to inspect the larger shale pieces. There was one item that I could not identify and I wonder if it might be part of an anomalocaris grasping appendage. Below are two pictures, one is a close-up and one that is a larger shot containing a trilobite cephalon for comparative purposes.

 

The spine at the end of the (maybe anomalocaris) lobe is not as long as most I’ve seen in pictures but I did find one from China that resembled the one in the picture rather closely.

 

 

Would any of you kindly venture an opinion as to what I may have found? Thanks in advance.

They look like trilobite thoracic segments.

Yep. Trilobite thoracic segments.  Good call, @connorp  !!

Nice cephalon from an Olenellus trilobite, but I don’t think there is enough to determine the exact species.

Thanks to those responding. I appreciate the help.
