The end of the Oligocene was a time of great sirenian diversity. Crenatosiren represents a medium-sized dugongid that would have been contemporary with the smaller Metaxytherium and larger Dioplotherium 23 million years ago. These three varieties of sea cows were able to overlap ranges because they were each adapted to feeding on very particular varieties of sea grasses which rooted at subtly different depths. This, like today’s tropical rainforests, is an exemplary story of abundant plant diversity driving abundant animal diversity.
