Cochilius brevirostrus

Mammalia - Notoungulata - Interatheriidae

Discussion

Amended Diagnosis: Cochilius brevirostrus differs from C. volvens and C. fumensis by exhibiting P2 with a small central fossette after the lingual union of the protoloph and metaloph; M13 with parastyle usually labially projected beyond the paracone and metacone; M12 with the protoloph more developed than the metaloph; and M3 with disto-lingual notch. Cochilius brevirostrus differs from C. fumensis by the presence of continuous dentition (Fernández et al. 2021).

Taxonomy

Cochilius brevirostrus was named by Bordas (1939). Its type specimen is MACN-PV 11745, a partial skull (Incomplete skull with badly preserved right and left I3–dP1–P2–M3), and it is a 3D body fossil.

Synonyms

Protypotherium minor was named by Bordas (1939). Its type specimen is MACN Pv 11742 and is a 3D body fossil.

It was recombined as Cochilius minor by Bordas (1939), Kramarz et al. (2015); it was synonymized objectively with Cochilius brevirostrus by Fernández et al. (2021).
Paracochilius chubutensis was named by Bordas (1939).

It was synonymized objectively with Cochilius brevirostrus by Fernández et al. (2021).
