Plate 13: figs 7-9

Material.

LFU 8336 SG015227 #3; two thin sections .

Dimensions.

(LFU 8336SG015227#3).

Remarks.

The present specimen has a decameral septal symmetry with three septal cycles. All other Eosiderastrea with such a symmetry and large corallite dimensions (as the present specimen) have four septal cycles. Hence, the present specimen is very probably a new species.
