. Bulletin of the British Museum (Natural History) Geology Supplement. «4 MESOZOIC AND CAINOZOIC DINOFLAGELLATE CYSTS Description. C. inodes has a fibrous body wall, bearing processes which give the reflected tabulation typical of this genus. The variability in the number of processes, noticed by Klumpp, has also been observed in the London Clay forms, especially in the sulcal region. The processes are either hollow, open distally with an ellipsoidal cross-section or taeniate. The process walls of the London Clay specimens are extremely fibrous and appear to be thinner than in the type material, perhaps due to oxidation within the sediment. C. inodes has been recorded from sediments ranging from the Lower Eocene to Middle Miocene in age. Material (Figured).
