Taxonomy

Venyukovioidea was named by Watson and Romer (1956). It is not extant.

It was reranked as the superfamily Venjukovioidea by King (1988); it was reranked as the infraorder Venyukovioidea by Rybczynski (2000), Fröbisch and Reisz (2011) and Cisneros et al. (2011).

It was assigned to Anomodontia by Olson (1962) and Kemp (1982); to Dicynodontia by King (1988); to Anomocephaloidea by Cisneros et al. (2011); and to Anomodontia by Rybczynski (2000), Kammerer and Angielczyk (2009) and Fröbisch and Reisz (2011).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis

Reference	Diagnosis
N. N. Rybczynski 2000	Anomodonts with conspicuous posterodorsal septomaxillary spur; parietal with contribution to skull table shorter anteroposteriorly than broad; pineal foramen raised on prominent boss.
C. F. Kammerer and K. D. Angielczyk 2009	Modesto et al. (1999), Modesto & Rybczynski (2000), Rybczynski (2000), Angielczyk (2004), Fröbisch (2007), and Fröbisch & Reisz (2008) all either provided explicit lists of autapomorphies for Venyukovioidea or presented data sets that can be used to derive such lists. Given that there is much overlap in character sampling among these data sets, the list of autapomorphies recognized by each are generally similar, although some differences are apparent. The most consistently cited autapomorphies are: (1) maxillary alveolar region long, occupying 72% or more of the length of the bone; (2) preparietal bone absent and interparietal suture anterior to pineal foramen greatly reduced by frontals; (3) pineal foramen raised on prominent boss; (4) parietal contribution to skull table shorter anteroposteriorly than broad; (5) premaxilla-palatine contact present.
