AB A revision of Renichnus arcuatus Mayoral, 1987, the vermetid attachmentetching trace fossil (fixichnia), is presented here with an emended diagnosis.Renichnus arcuatus should be used only for nested reniform depressionsarranged in linear series or solitary ones. A new ichnotaxon, Santichnusmayorali ichnogen. et ichnosp. nov., is described to name a bioerosionstructure that previous authors included under R. arcuatus. The new tracefossil comes from the Miocene–Pliocene deposits from Fuerteventura andLanzarote, Canary Islands, and is characterized as a shallow canal, semicircularin cross-section that occurs on the surface of hard substrates. Santichnusmayorali follows a logarithmic spiral path that may depart in its outer whorl in asomewhat straight shaft that becomes recurved back toward the spiral. From anactualistic point of view, this new ichnotaxon is interpreted as the anchoragebioerosion structure of vermetid gastropods. Given the close relationshipbetween the two ichnotaxa (Renichnus and Santichnus) that share vermetidgastropods as their tracemakers, it is proposed that they should be consideredas compound trace fossils when they occur interconnected.
