I think it is Onnia seunesi or Onnia superba, but i don't know exactly.

For the time being label it: Onnia sp.  Onnia seunesi was reassigned as Deanaspis seunesi by Pereira et al. 2018. 

 

The classification of Deanaspis and Onnia in Morocco will be addressed in a future paper.

Thanks for your reply!

 

Then, is it difficult to classify the onnia's species, because it needs more research?

There are specialists that are currently working on the Trinucleidae in Morocco. Because Onnia seunesi was reassigned as Deanaspis seunesi, a conservative approach with a label of Onnia sp. is preferable, until a future paper resolves the status of Onnia and Deanaspis with more clarity and updated systematic paleontology.
