Kaupitherium is an extinct dugongid sea cow that lived during the Oligocene.

Kaupitherium also had elongated ribs, presumably to increase lung capacity to provide fine control of buoyancy.

"Halitheriine" dugongid remains from Oligocene deposits in Europe were previously referred to Halitherium schinzii by many authors.

However, Voss (2013, 2014) dismissed Halitherium as a nomen dubium by virtue of being based on non-diagnostic remains.

Voss based the opinion on the type species, H. schinzii, being nomen dubium, with its holotype fossil, an isolated molar, having no diagnostic value.
