According to Dr Kate Darling, from the University of Edinburgh, "If some species can switch between free-swimming and bottom-dwelling lifestyles, then it's possible that most planktic foraminifers
may have survived the late Cretaceous extinction in the sediment, not in the plankton.
Due to the relative proximity of the sampling sites to the shore, foraminifers
were found to be scarce and the required number of 300 specimens per sample could not be obtained for most samples.
Samples were split by settling to >300 foraminifers
, and a census was made of all foraminifers
and arcellaceans >45 [micro]m.
Limestones (packstone) with foraminifers

By drilling some limestones, characterized by typical shallow reef (right-hand photo on page 112) assemblages with small and age-diagnostic larger benthic foraminifers
, and radiogenicly dating the volcanic basement in several sites (such as the early Eocene, about 55 million years ago, in the Maldives), the Chagos-Laccadive Ridge, along with the Mascarene Plateau, was also found to be part of the volcanic track for a hot spot located today under the island of Runion.
The UE consists of greenish marlaceous clays with silicon sandstone inter-layers, foraminifers
, shales of ostracordes.
Small ostracods, sponge spicules, agglutinated foraminifers
, gastropods, bivalves, brachiopods, fragments of conularids and bryozoans occur in the residues.
It is characterized by the fauna of foraminifers
, ammonites, pelecypods and belemnites.
18]O of benthic foraminifers
is therefore a record of high-latitude surface ocean change, and that change need not have occurred at the same rime at high northern and at high southern latitudes (Blunier and Brook 2001).

The Upper Eocene (UE) consists of greenish marlaceous clays with silicon sandstone inter-layers, foraminifers
, shales of ostracordes and the teeth of fish.
