I recently purchased a lot of trilobites with 2 of the trilobites in mind. Also included in the lot was this which I believe is the ventral side of a morroccan lichid. My first thought was Ceratarges but it's missing the outer pygidial spines. If anyone has any idea what species this trilobite is I'd appreciate the input. Unfortunately the specimen appears to be quite distorted so identification may not be easy.
