Steiromys is an extinct genus of caviomorph rodent that lived in South America during the Miocene epoch.[1]
Taxonomy
[edit]Originally, the species Eosteiromys annectens was classified as a member of the genus Steiromys. However, detailed taxonomic study has moved the species to the genus Eosteiromys.[2]
Palaeobiology
[edit]Locomotion
[edit]The foot morphology of Steiromys suggests it may have been scansorial.[3]
