Sirenians between myth and science

Nymphaea. Folia Naturae Biharie
Sirenians (also known as sea-cows), as we know them today, represent an order of fully aquatic herbivorous mammals, with a rich fossil record that spans from the Paleogene to the Holocene. In fact, sirenians are the only marine full herbivorous mammals, the others having different diets.

Utility and Design of Aerial Surveys for Sirenians

2012
[Extract] Aerial surveys have been used as a tool to assess aspects of sirenian biology for three decades. Although aerial surveys can be a useful method of assessing sirenian population distribution and abundance, they can be logistically difficult and expensive and may not always be the appropriate method.

Estimating body size of fossil sirenians

Marine Mammal Science, 2010
Estimates 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, 2006
The 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.

Ascaridoid nematodes of Sirenians—the Heterocheilinae redefined

Journal of Helminthology, 1980
AbstractThe 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.

Conservation of marine mammals: pinnipeds and sirenians

2020
Marine mammals are a broad group of mammals adapted to the aquatic life which depend on the ocean for most or all their life needs. Pinnipeds are highly specialized aquatic carnivores that live in a variety of marine habitats, including freshwater for some of them.
