Abstract:

The Middle Eocene echinoid fauna of Gebel Qarara is large and diverse. Twenty four species in seventeen genera are identified and described. Three species of them are new: Echinocyamus belali, Antillaster farisi and Metalia lindaae. The Caribbean genus Antillaster which is recorded for the first time from the Mediterranean region, suggests an east – west migration from the Tethys and Paratethys to the Caribbean region during the Eocene time by crossing the Atlantic Ocean in a westerly direction. The paleoecology and the paleogeography of the echinoid fauna are discussed. The paleoecological study appears to revel that the Middle Eocene rocks of that area were deposited in a shallow marine water conditions. Paleogeographically, 33.3% of the total echinoids are endemic to Egypt, 66.7% species are similar to that of the taxa of the adjacent countries.
