Trilobite

Bavarilla

Fezouata trilobite

Bavarilla is an Early Ordovician calymenoid trilobite of the Fezouata Formation with a granular surface and a rounded glabella, found in the same orange siltstones as Asaphellus and sometimes with preserved appendages. It is less common than Asaphellus and more distinctive; complete specimens are worth more.
