Along the Egyptian Red Sea Coast from Abu Darag on the Gulf of Suez southwards to
Berenice, 19 species form the most common invertebrates that inhabit the widely distributed
rocky shore niches. These species belong to Bivalvia, Gastropoda, Bryozoa, Annelida, and
Cirripedia. They are all also recorded as fossils from the Pleistocene, some of them are dated
back to the Pliocene. The recorded species have different modes of life: encrusters, clingers,
crawlers, .and byssate. Most of them tolerate the strong ecological stresses of the tidal zone
The transgressive-regressive Miocene succession exposed at gabals Geneife, Homeira
and Gharra in Cairo-Suez District is unconformably underlain and overlain by continental
sediments of Oligocene and post Miocene (?) respectively. It could be differentiated into two
rock-units from base to top, Gharra Formation and Genefe Formation. Thirty eight macrofossil
species (26 bivlaves, 7 gastropods and 5 echinoids) have been identified and photographed.
They belong to 19 genera and 15 families. The paleogeographic and biogeographic distribution

Sixty-three invertebrate species (19 foraminifers, 4 bryozoans, 20 gastropods and 20
bivalves) from four lagoons along the Red Sea Coast have been identified, illustrated and their
habitat, bio-aM-paleogeographic distribution (if present) were done. They belong to 48 genera
and 34 families. The habitat of the recorded fauna indicated that they belong to Indo-Pacific
affinity and few of them also have Mediterranean-Atlantic one. Um EI-Howitat lagoon sediments
are enriched in Fe, Mg, Pb, Co and Cu that attributed to the anthropogenic inputs, and
