Corals rudisti an entirely disappeared in KT phenomenon. For geologists, reefs study of corals paleocen is ambiguous: it found few such reefs rarelymainly because paleocene exposed rocks which were formed in tropical conditions. This seems to show that corals have not recovered very quickly after the KT extinction. But they prospered in the warmer waters of the age next Eocene.
Calcareous phytoplankton - single plant with a shell of calcite, in which floating
water column - as cocolitoforii and foraminiferii have suffered serious losses during the KT phenomenon but somehow regain their former diversity in age and paleocen Eocene. These tiny organisms, along with diatomeele and dinoflagellate similar size, have made much of the productivity of the ocean during the Cenozoic era, as they did in a cretaceous. Rocks formed during paleocenului show that "marine ecosystems have been expanded to include new penta ecological niches of the ocean along the banks, while continuing to be continents away from each other.
Distribution of continents in the first part of the Cenozoic era was very similar to the one today, but the opening of high tension continental platform areas offered new colonization of animals such as a unusually large cucumber called bucks sand. Penny sand are the only sea cucumbers that are able to live down the sandy beach and there today. Their ancestors in the form of biscuits are found in large numbers on the continental platform from the beginning of large-ceno Zoica and probably used the same technique of rapid burial in quicksand not to be dragged by the waves.
