Late Pleistocene reef fauna from the Red Sea coast, Northwest Saudi Arabia
The Late Pleistocene reef unit of the last interglacial marine isotope stage 5e stretches all over most of
the coastal cliffs and wadi cuts and interrupted only in wadi entrances along the Red Sea coast,
northwest Saudi Arabia. It studied and sampled from 12 localities between Duba and Sharma for microand
macrofossils record. Twenty-four foraminifera, 67 coral, 79 gastropod and 63 bivalve species were
identified. The identified assemblages, particularly scleractinians indicated a deepening upward pattern
for the studied late Pleistocene reef unit, starting with a coral assemblage of coral rock zone at the base,
above a conglomeratic bed, followed by reef crest facies, and grades into the upper reef slope
assemblages. The recorded taxa mostly have the Indo-Pacific affinity, and few elements have Atlantic-
Mediterranean and cosmopolitan realm.

Heavy metal contamination in soil is a global issue threatening human health and
ecosystems. Accurate spatial maps of heavy metals (HMs) are vital to mitigating the adverse
effects on the…
