Abstract

The fossil content of the mainly Pleistocene, marine terraces I, II, III, IV, V, VI, VII and XI from the Jorós Valley (Jandía, Fuerteventura Island) is studied. They differ in the type of outcrop, taphonomic signatures, and diversity and abundance of bivalves, gastropods, corals, cirripeds, calcareous algae, benthic foraminifers and fish tooth, but terraces II and VII are the richest in fossils. Isotopic C and O signals from whole shells of the ostreid Ostrea virleti range from 1,34 to 1,88%o 13CPDB and -0,36 to 0,9%o 18OPDB. Minimal values from O recorded in IV terrace are interpreted as indicative of the highest sea surface temperature. The content of heavier O isotope increases progressively from terraces V to VII, suggesting a moderate decrese of temperature. These features suggest shallow coastal environments for all the studied marine terraces, with sea surface temperatures somewhat higher than the present.
