ABSTRAK
Lima belas spesies fosil ostracoda berumur Miosen dari Formasi Cimandiri telah dianalisis dari 6 conto sedimen yang berasal dari penampang stratigrafi lintasan S. Cimerang, Sukabumi. Analisis mikrofosil secara kuantitatif , memperlihatkan ostracoda Miosen tersebar pada litologi batulempung. Ostracoda yang melimpah pada lintasan ini adalah Hemicytheridea ornata, Cytherella hemipuncta, Hemicytheridea reticulata, Cytherelloidea excavata, Cyherella javaseanse, and Keijella carrirei.
Berdasarkan kumpulan ostracoda, diketahui bahwa lingkungan pengendapan daerah penelitian adalah laut dangkal.

ABSTRACT
Fifteen species of fossil Ostracoda are describe from six sediment samples from Middle Miocene Cimandiri Formation, Sukabumi, West Java define from geological measure section profile Cimerang River. Microfossil Analysis based on quantitatively method, the distribution of Miocene Ostracoda be discovered in claystone lithology. Abundant ostracods are Hemicytheridea ornata, Cytherella hemipuncta, Hemicytheridea reticulata, Cytherelloidea excavata, Cyherella javaseanse, and Keijella carrirei. Based on the distribution of Ostracoda, it is known that the depositional environment of the study area is shallow sea.
