Astrceopora, Porites very common. Lohophytum and detached alcyonarian spicules 

 are present. The corals are largely overgrown by Polytrema planum and Lithothamnion. 

 Fine detrital sediment with OrhitoUtes, very abundant ; PlanorhuUna, Carpenteria, 

 Gypsina, Nonionina, and Ampliistegina. Echinid spines and casts of gastropods fill 

 the spaces between the corals. Infilled borings of Cliona,
