Name: Astycoryphe sp. Richter,1919
Stratigraphy: Bou Dib formation, Givetian
Locality: '2cc' couche, Jebel Mrakib
This is a small and rare trilobite from the 'devil-horned cyphaspis' (2cc) couche in Jebel Mrakib (referring to the presence of Cyphaspis walteri). This specimen, most likely an exuvium, is missing both librigenae. Note the single tropidium on the anterior margin in front of the glabella.

Name: Tropidocoryphe cf. sculptaridgiata Molinaro,1919
Stratigraphy: El Otfal formation, Eifelian
Locality: Otarionella couche, Jebel Issoumour
Tropidocoryphe with a complex tropidium. T. sculptaridgiata is considered a nomen nudum, as the species has not yet been formally described.
