Pteriomorphia

Bivalvia

Taxonomy

Pteriomorphia was named by Beurlen (1944). It is extant.

It was reranked as the unranked clade Pteriomorphia by Giribet and Wheeler (2002), Bieler and Mikkelsen (2006); it was reranked as the superorder Pteriomorphia by Bouchet et al. (2010); it was reranked as the infraclass Pteriomorphia by Carter et al. (2011), Bieler et al. (2014), Schnetler et al. (2024).

It was assigned to Pelecypoda by Ward and Blackwelder (1987); to Autolamellibranchiata by Giribet and Wheeler (2002), Bieler and Mikkelsen (2006); to Bivalvia by Newell (1965), Adegoke (1977), Grant-Mackie (1978), Vokes (1980), Gliozzi and Malatesta (1983), Ward (1992), Cope (1996), Cope (1997), Reid (1998), Squires (1999), Todd (2001), Damborenea (2002), Spencer et al. (2004), Lin et al. (2007), Hikuroa and Grant-Mackie (2008), Scholz et al. (2008), Waller (2011); to Autobranchia by Bouchet et al. (2010), Carter et al. (2011), Bieler et al. (2014); and to Autobranchia by Schnetler et al. (2024).
