Good afternoon.
This fish and mold with neither head or tail comes from the same group of concretions that yielded the Devonian trilobite Eldredgeia.
The specimen is a body of 29 mm in length and 15 mm at its widest part. The lack of head complicates the ID. I believe it is a small type of cephalaspis such as Pattenaspis, Mimetaspis o Diademaspis, but I am looking for help to ID it.
I would appreciate any help I can get
Thank you,
