Low-diversity conodont and cephalopod assemblages from the Silurian of the Tinduf Basin, Western Sahara

A peculiar cephalopod slab collected in Western Sahara hosts almost monospecific cephalopod and conodont associations, preliminarily attributed to the Ludfordian based on the occurrence of Wurmiella sp. A Corriga et al., 2021. Arionoceras submoniliforme (Meneghini, 1857) dominates the nautiloid fauna that reveals a clear bimodal orientation. The microfacies analysis documents a cephalopod packstone associated with abundant skeletal elements coated by micrite. The origin and significance of this association are discussed and possibly interpreted as a post-Lau Event fauna, still deeply affected by the extinction event.
