moroccan trilobite ID confirmation

[HannahB]

hi i bought this enrolled trilobite today, it is listed as Pedinopariops brongniarti but i’ve had experience with this shop mislabelling trilobite species and wanted to double check with the experts on here!

@piranha might have an answer to that.

Pedinopariops brongniarti is a European species. In Morocco the taxon is Pedinopariops (Hypsipariops) vagabundus. However, according to Van Viersen & Koppka 2021, it is elevated to a generic rank (Hypsipariops vagabundus) and no longer classified with a rank of subgenus. The tubercles on the glabella are not a good match with Hypsipariops vagabundus, and unfortunately, the poor preservation of the eye lenses makes it difficult for any confident ID.  I would label it conservatively: Phacopidae sp.
