- According to a paper published in the Journal of Vertebrate Paleontology, a newly found fossil indicates that Vishnuonyx had travelled as far as Germany.
About
- Researchers from the Universities of Tübingen and Zaragoza have discovered the fossil of a previously unknown species, which they have named Vishnuonyx neptuni, meaning ‘Neptune’s Vishnu’.
- The species was discovered from 11.4-million-year-old strata in the area of Hammerschmiede, which is a fossil site in Bavaria, Germany that has been studied for about 50 years.

- This is the first discovery of any member of the Vishnuonyx genus in Europe.
- It is also its most northern and western record to date.
- Vishnuonyx were mid-sized predators that weighed, on average, 10-15 kg. Before this, the genus was known only in Asia and Africa (recent findings show that Vishnuonyx reached East Africa about 12 million years ago).
- Vishnuonyx depended on the water and could not travel long distances over land.
- Its travels over 6,000 km were probably made possible by the geography of 12 million years ago when the Alps were recently formed.
- These Alps and the Iranian Elbrus Mountains were separated by a large ocean basin, which would have made it easier for the otters to cross it.
- Members of a genus of Vishnuonyx lived in the major rivers of southern Asia between 12.5 million and 14 million years ago,
- Fossils of these now extinct otters were first discovered in sediments found in the foothills of the Himalayas.
