Eopachyrucos is an extinct genus of interatheriid notoungulates that lived from the Middle Eocene to the Late Oligocene of Argentina and Uruguay.[1] Fossils of this genus have been found in the Sarmiento Formation of Argentina and the Fray Bentos Formation of Uruguay.[2][3]
Taxonomy
Eopachyrucos was first named in 1901 by Florentino Ameghino based on fragmentary remains found in the Sarmiento Formation of Argentina.[4] He originally considered it as a member of the family Hegetotheriidae, as an ancestor of Pachyrukhos, as reflected in its name ("dawn Pachyrukhos"), however, recent studies have confirmed it to be a member of the family Interatheriidae, more specifically within the subfamily Interatheriinae.
The following cladogram of the Interatheriinae is based on Vera et al. 2017, showing the position of Eopachyrucos.[5]
