Are These Trilobites Fake?

[Guguita2104]

I bought these specimens in a fossil market-place.Then I repaired they had some holes (typical of fakes done of resin)..Are they fakes or not?If not, what are their species ?

These trilobites are unlikely to be fake. The species is Flexicalymene ouzregui; here is a link to a discussion of the species. They are very common Moroccan trilobites, too inexpensive to be worth faking. The preservation of your specimens is fairly typical.

Trilobites like that are typically Flexicalymene ouzregui or Diacalymene ouzregui. They come from the Ordovician age Ktaoua Formation in the Sahara Desert in Morocco near the town of Tazoulait. This formation is the same one that yielded the recent discovery of the anomalocarid, Aegirrocaris. These trilobites are found naturally and are very rarely faked. It the the Devonian ones from the Hamar Laghad Formation you have to worry about, especially Dicranurus which are frequently cast from resin.
