Mammalia - Sparassodonta

Taxonomy
Sipalocyon pusillus was named by Ameghino (1891) [Name: Nuevos restos de mamiferos fosiles]. Its type specimen is MACN 666, a mandible (fragment of right ramus with alveoli of i1-3, c, p1-2, anterior root of p3, posterior half of p3, anterior half of m1, posterior root of m1, anterior alveolus o), and it is a 3D body fossil. Its type locality is Cerro Observatorio, which is in a Santacrucian terrestrial horizon in the Santa Cruz Formation of Argentina. It is the type species of Pseudonotictis.

It was recombined as Pseudonotictis pusillus by Marshall (1981).

Its type specimen is MLP 11-26, a partial skeleton (left dentary with p1, p3-m4; right dentary with p1-3; skull fragments including right maxilla with M2; humerus, radius, ulna, metapodials), and it is a 3D body fossil. Its type locality is Monte León, which is in a Santacrucian terrestrial horizon in the Santa Cruz Formation of Argentina.

    It was synonymized subjectively with Sipalocyon pusillus by Ameghino (1894) and Marshall (1978); it was synonymized subjectively with Pseudonotictis pusillus by Marshall (1981).
