Anisolambdinae is an extinct subfamily of litoptern ungulates known from the Eocene–Miocene of South America. Members of the group are only known for the brachydont teeth.[2]

Etimology

Anisolambdinae refers to their similarity to the type taxon: Anisolambda.[3]

Description

The anisolambdines are small litopterns known only by teeth. They have a well developed paralophid in the lower molars, ending in a large paraconid.[3]

They are found in Argentina, Brazil and Colombia.[1]
