Procolophoninae

Reptilia - Procolophonidae

Taxonomy

Procolophoninae was named by Nopcsa (1928) [Actually should be created off Lydekker 1889 but cannot be because Nopcsa retains both.].

It was assigned to Procolophonidae by Kuhn (1946), Colbert (1946), Novikov (1991), Novikov and Orlov (1992), Spencer and Benton (2000), Modesto et al. (2002), Cisneros (2008), Cisneros (2008).

Subtaxa

Microtheledon, Myocephalus, Orenburgia (syn. Lestanshoria, Insulophon, Samaria), Procolina, Procolophon, Thelegnathus parvus, Timanophon

Synonyms

Microtheledon was named by Broom (1936). It is not extant. Its type is Thelegnathus parvus.

It was considered a nomen dubium by Colbert (1946).

It was assigned to Procolophonidae by Huene (1939), Carroll (1988).
Thelegnathus parvus was named by Broom (1905). It is a 3D body fossil. Its type locality is Aliwal North Area, which is in an Anisian terrestrial siliciclastic in the Burgersdorp Formation of South Africa. It is the type species of Microtheledon.

It was recombined as Microtheledon parvus by Broom (1936), Huene (1939); it was considered a nomen dubium by Colbert (1946).
