Estimating body size of fossil sirenians
Marine Mammal Science, 2010Estimates of fossil sirenian body size are important for understanding niche partitioning among possibly sympatric species. Because of the paucity of complete fossil skeletons, we explored the utility of three morphometric predictors of body size: (condylobasal skull length [BSL]; occipital condyle width [OCW]; and foramen magnum width [FMW]) in extant

Sirenians in southern Australia—first fossil record
Alcheringa: An Australasian Journal of Palaeontology, 2006The anterior half of the right mandible of a dugong is described from the early Pliocene Loxton Sands of the Murray Basin in South Australia. This is the oldest dugong fossil known in Australia, and, although not identifiable, is possibly antecedent to or the oldest representative of the genus Dugong.

Human Interactions with Sirenians (Manatees and Dugongs)
2017There are three extant sirenian species of the Trichechidae family and one living Dugongidae family member. Given their close ties to coastal and often urbanized habitats, sirenians are exposed to many types of anthropogenic activities that result in challenges to their well-being, poor health, and even death.

Ascaridoid nematodes of Sirenians—the Heterocheilinae redefined
Journal of Helminthology, 1980AbstractThe two ascaridoids of sirenians, Heterocheilus tunicatus Diesing, 1839, and Paradujardinia halicoris (Owen, 1833), are redescribed. A basic affinity between the two species is indicated in the bilateral structure of the excretory system, the globular ventriculus, long intestinal caecum, and the form of the male tail.

The readaptation of Eocene sirenians to life in water
Historical Biology, 2000Eocene sirenians and cetaceans simultaneously and independently evolved similar morphological adaptations to aquatic life. These included increased flexibility in the sacral region, reduction and loss of hind limbs, shortening of the neck, increased skeletal mass, and other modifications.
