Shelly fossils from the basal Middle Cambrian, near the peak of Tizi n'Tichka in the central High Atlas, Morocco, include the new hyolithids Oboedalites peregrinus new species, Emarites decorissimus new genus and species, Patholites insolitus new genus and species, Rodentilites cricetus new genus and species, Slapylites afer new species, Tajinella mosei new genus and species, and Tizilites creber new genus and species. New orthothecid hyoliths are Gracilitheca destombesi new species, Contitheca chrosniaki new species, Sysoievia exilis new genus and species and an indeterminate species of Circotheca. The presence of Obeodalites, Slapylites, and Contitheca suggests a strong affinity to other Mediterranean and to Avalonian faunas. Their occurrence in Morocco extends their geographic ranges from Europe, and further reenforces their usefulness as indicators of Middle Cambrian age.
