South of the Daua river, in N.E. Kenya, the Hereri Shales of Joubert (i960 : 24) 

 are referred to the Kimmeridgian mainly on stratigraphical grounds, as no ammonites 

 identifiable with certainty have been found in them. The following species from 

 Hereri are recorded in the present work : 



Grammatodon (Indogrammatodon) irritans (Hennig) 



Mytilus (Falcimytilus) jurensis Roemer 



Eopecten thurmanni (Brauns) 



Chlamys curvivarians (Dietrich) 



Exogyra nana (J. Sowerby) 



Protocardia {Tendagurium) bannesiana (Contejean) 



Cer atomy op sis striata (d'Orbigny) 



Ceratomya excentrica (Roemer) 



Bourguetia saemanni (Oppel) 



The presence of Protocardia bannesiana appears, from its known European 

 occurrences, to confirm the Kimmeridgian age of the above assemblage. 



In the same area the succeeding Dakacha Limestones are considered by Joubert 

 (i960 : 28) as " probably bridging the uppermost Kimmeridgian and the lowest part 

 of the Tithonian ", thus being approximately contemporaneous with the dinosaur 

 beds of Tendaguru. No ammonites have been found in them, but they have 

 yielded the following bivalves and gastropods, described in the present work : 



Nuculoma (Palaeonucula) bellozanensis sp. nov. 

 Modiolus virgulinus (Thurmann & Etallon) 

 Modiolus (Inoperna) perplicatus (Etallon)
