Procolophonids
Procolophonidae is an extinct family of small, lizard-like parareptiles known from the Late Permian to Late Triassic that were distributed across Pangaea, having been reported from Europe, North America, China, South Africa, South America, Antarctica and Australia. The most primitive procolophonids were likely insectiovous or omnivorous, more derived members of the clade developed bicusped molars, and were likely herbivorous feeding on high fiber vegetation or durophagous omnivores. Many members of the group are noted for spines projecting from the quadratojugal bone of the skull, which likely served a defensive purpose as well as possibly also for display. At least some taxa were likely fossorial burrowers. While diverse during the Early and Middle Triassic, they had very low diversity during the Late Triassic, and were extinct by the beginning of the Jurassic.

Suchonosaurus
''Suchonosaurus'' is an extinct genus of procolophonid reptile from the Late Permian of Russia. It is monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispec ..., including the species ''Suchonosaurus minimus'', which is itself known only from a single fragment of the upper jaw.

Coletta (genus)
''Coletta'' is an extinct genus of basal procolophonid parareptile from Early Triassic (Induan stage) deposits of Eastern Cape Province, South Africa. It is known from the holotype GHG 228, a skull with fragmentary lower jaws. It was collected on the farm Brakfontein 333 in the Cradock District. It was found in the Katberg Formation of the Beaufort Group (Karoo Basin) and referred to the ''Lystrosaurus'' Assemblage Zone. It was first named by Christopher E. Gow in 2000 and the type species is ''Coletta seca''. ''Coletta'' was one of the most basal procolophonids, showing similarities to owenettids such as ''Owenetta''. The generic name ''Coletta'' references both ''Procolophon'' and ''Owenetta'', signifying its transitional nature. The specific name ''C. seca'' refers to seca, a Latin word referring to any stabbing weaponry. This is based on large, fang-like teeth on its vomer The vomer (; lat, vomer, lit=ploughshare) is one of the unpaired facial bones of the skull. It i ...
