Satherium piscinarium (Hagerman's otter) is an extinct genus and species of giant otter of North America that lived during the Pliocene through Pleistocene from ~3.7–1.6 Ma. (AEO).[1] existing for approximately 2.1 million years.

Satherium piscinarium is stated to be related to the giant otter of Brazil and Surinam.[2][3]

Fossil distribution

Fossil specimens were found from western Washington in the northwest, the border of California and Nevada near Reno, from Idaho to Nebraska, from Oklahoma south to Florida. Idaho yielded the largest number of collections of S. piscinarium.

Taxonomy

Satherium piscinarium was originally named Lutra piscinaria by Joseph Leidy in 1873. In 1937, it was recombined as Satherium piscinarium by Barbour and Schultz. Recombination again by Bjork in 1973, Kurten and Anderson in 1980,[4] and Willemsen in 1992.

Morphology

Body mass was estimated by Legendre and Roth (1988). [5]

  • Specimen 1 was estimated to weigh: 17 kg (37 lb)
  • Specimen 2 was estimated to weigh: 18 kg (40 lb)
