Didymoconida

Osteichthyes - Didymoconida

Taxonomy

Didymoconidae was named by Kretzoi (1943). It is not extant.

It was reranked as the order Didymoconida by Lopatin (2001), Lopatin (2006).

It was assigned to Palaeoryctoidea by Van Valen (1967), Mellett and Szalay (1968); to Mesonychoidea by Gingerich (1982); to Mesonychia by Lopatin (1997); to Eutheria by Lopatin (2001); and to Insectivora by Lopatin (2006).

Synonyms

Tshelkariidae was named by Gromova (1960). It is not extant.

It was synonymized subjectively with Didymoconidae by Van Valen (1967).
Didymoconus berkeyi was named by Matthew and Granger (1924). Its type specimen is AMNH 19001, a mandible (Lower jaws), and it is a 3D body fossil. Its type locality is Loh, which is in an Oligocene terrestrial horizon in the Hsanda Gol Formation of Mongolia.

It was considered a nomen dubium by Lopatin (1997).
