Fiandraia
Fiandraia is an extinct monotypic genus of notoungulate that lived in Uruguay during the Oligocene and the Early Miocene. It was found in the Fray [Bentos Formation], in rocks dated back from the Deseadan period.
The taxonomic status of Fiandraia has been historically disputed; in 1976, its discoverer, Francisco [Lucas Roselli|Roselli], assigned it in the family Mesotheriidae; in 1978, in Mones & Ubilla, it was considered part of Interatheriidae; McKenna & Bell, in 1997, placed it inside its own family, Fiandraiinae, itself part of Mesotheriidae; Flynn et al considered it, in 2005, as a member of the Toxodontidae instead of the Mesotheriinae.
