While fossils are abundant, the number of species is not great in 

 comparison with the fauna of the Grande Gr^ve limestones on the 

 Forillon.

This is clearly the Grande Greve fauna but the 43 species here listed 



are in notable numerical contrast to the 150 of the Forillon limestones. 



There are other differences in the faunal combinations. Thus the follow- 

 ing species are common to both regions : 



Phacoi)s logani {var?) 

 Proetus j)hocion 

 Ceratocephala robinia 

 Tentaculites elongatus 

 Conularia cf. desiderata 



Platyceras tortuosum 

 Diaphorostoma (perceense, affine) 

 Actinopteria communis? 

 Lingula elliptica 

 L. rectilatera
