Astrapotherium ruderarium

Mammalia - Astrapotheria - Astrapotheriidae

Taxonomy

Parastrapotherium ruderarium was named by Ameghino (1902). Its type specimen is MACN A 52-224, a mandible (right mandibular fragment with dp3-dp4, posterior portion of m1, m2, erupting m3), and it is a 3D body fossil.

It was recombined as Astrapotherium ruderarium by Kramarz and Bond (2010).

Synonyms

Astrapotherium triangulidens was named by Ameghino (1902). Its type specimen is MACN A 52-523, a set of teeth (two probably associated fragments of upper canines), and it is a 3D body fossil.

It was synonymized subjectively with Astrapotherium ruderarium by Kramarz and Bond (2010).
Parastrapotherium paucum was named by Ameghino (1902). Its type specimen is MACN A 52-525, a set of teeth (three incisors, two isolated cheek teeth), and it is a 3D body fossil.

Astrapothericulus laeviusculus was named by Ameghino (1902). Its type specimen is MACN A 52-212, a set of teeth (probably associated dp4, four deciduous incisors, fragment of lower canine, fragment of upper canine), and it is a 3D body fossil.

It was synonymized subjectively with Astrapotherium ruderarium by Kramarz and Bond (2010).
Astrapotherium minusculus was named by Ameghino (1902). Its type specimen is MACN A 52-511, a set of teeth (probably associated DP3, two deciduous incisors, fragment of lower canine, fragment of dp3), and it is a 3D body fossil.

It was recombined as Astrapothericulus minusculus by Ameghino (1902); it was synonymized subjectively with Astrapotherium ruderarium by Kramarz and Bond (2010).
Prochalicotherium patagonicum was named by Ameghino (1902). Its type specimen is MACN A 52-337, a tooth (isolated right P4), and it is a 3D body fossil.
