Trilobites
Order Lichida Family Odontopleuridae
Geologic Age: Lower Ordovician
Trilobite is 30 mm long
Fezouata Formation, Zagora, Morocco
Comments: The preservation of the Fezouata Formation is often reddish
color seen here as a result of oxidation of pyrite subsequent to deposition.
This phenomena is also found in many Chengjiang fossils.
This Selenopeltis is very different from others from Morocco. It is
highly similar to
Selenopeltis gallica, but differs in the fact that it lacks the small occipital
spines of that trilobite. As a consequence it is most likely the rare Selenopeltis
macrophthalma, which although known from Morocco has usually only been
seen as fragments. The odontopleurid trilobite Selenopeltis is in association
with an nautiloid and a brachiopod.
