Daguinaspis is an early Cambrian trilobite genus found in Morocco. Like the closely related Choubertella and Wolynaspis, but unlike any other Fallotaspidoidea, it lacks genal spines.

Distribution

[edit]

Cambrian of the Anti-Atlas, Morocco, 30.4° N, 8.8° W (Daguinaspis trilobite zone, Tazemmourt Section[2] and Tiout Section.[3] Amouslek Formation, Middle Atdabanian (520.0 - 516.0 Ma) )

Ecology

[edit]

Daguinaspis occurs together with the trilobites Marsaisia robauxi and Resserops bourgini, and the brachiopod Brevipelta chouberti (Tazemmourt), and also with the problematic Microschedia amphitrite (Tiout).
