Procolophoninae
Procolophoninae is an extinct subfamily of procolophonid parareptiles from the late Early Triassic to the early Middle Triassic (Olenekian and Anisian stages) of Africa, Antarctica, Asia, Europe and South America. Currently, the oldest-known procolophonine is Procolophon from the earliest Olenekian stage.[1]

Phylogeny
Procolophoninae was named in 1890 by Richard Lydekker. It is a stem-based taxon defined phylogenetically for the first time by Modesto et al. (2002) as "all taxa more related to Procolophon trigoniceps Owen, 1876 than to Leptopleuron lacertinum Owen, 1851".[2] The cladogram below follows Ruta et al. 2011.[1]
