Proheptaconus patagonicus

Osteichthyes - Panameriungulata - Adianthidae

Taxonomy
Adianthus patagonicus was named by Ameghino (1904). Its type specimen is MACN A52-218, a tooth (left M3), and it is a 3D body fossil. Its type locality is Gran Barranca - southern cliff of lake Colhué Huapí, which is in a Colhuehuapian terrestrial horizon in the Sarmiento Formation of Argentina.

It was recombined as Proheptaconus patagonicus by Cifelli and Soria (1983).

Synonyms
  • Proheptaconus trelewense was named by Bordas (1939). Its type specimen is MACN 11453, a skull (poorly preserved skull with endocast and with broken left P4-M1 and right M1 and M3), and it is a 3D body fossil. Its type locality is Southern Cliff of lower Chubut River Valley, near Gaiman, which is in a Colhuehuapian paralic mudstone in the Sarmiento Formation of Argentina.

    It was corrected as Proheptaconus trelewensis by Bordas (1939); it was synonymized subjectively with Proheptaconus patagonicus by Cifelli and Soria (1983).
