Nineteen species of Dinoflagellate have been found in the coal deposits of El-Maghara, Safa Formation, north central Sinai. The dominant recorded species are: Lithodinia jurassica, Leptodinium antigonium, Gonyaulacysta sp., Chytroeisphaeridia cf. mantellii, Sentusidinium echinatum, Cassiculosphaeridia magna apd Exiguisphaera cf. phragma. Bajocian-Bathonian age of the coal deposits of El-Maghara could be confirmed. The data suggest a paralic origin for the
coal of El-Maghara.

Key words: Dinoflagellate, coal deposits, Sinai, Egypt, Middle Jurassic.
