Guilielmofloweria
''Guilielmofloweria'' is an extinct genus of proterotheriidae, proterotheriid litopterna, litoptern that lived from the Middle to Late Eocene of what is now Argentina. Fossils have been found in the Sarmiento Formation of Argentina. Taxonomy ''Guilielmofloweria'' was first named in 1901 by Florentino Ameghino based on fragmentary remains found in the Sarmiento Formation of Argentina, in rocks dating back to the Middle Eocene. He originally considered it a member of the pantodonta, pantodont family Pantolambdidae, but recent studies have shown this to be incorrect, as Richard Cifelli considered it as a member of the litoptern family Proterotheriidae, more specifically within the subfamily Anisolambdinae. Anisolambdinae (also called Anisolambdidae in some studies) was proposed to unite the primitive and earlier forms ''Anisolambda'', ''Eolicaphrium'', ''Heteroglyphis'', ''Lambdaconops'', ''Paranisolambda'', ''Protheosodon'', ''Wainka'' and ''Xesmodon''. However, the phylogenetic a ...
