''Anniealexandria'' is an extinct genus of amphisbaenian lizard known by the type species ''Anniealexandria gansi'' from the earliest Eocene of Wyoming. ''Anniealexandria'' is the only known member of the family Bipedidae in the fossil record, which otherwise only includes the extant genus ''Bipes'' from Mexico. It was named in 2009 in honor of Annie Montague Alexander, founder of the University of California Museum of Paleontology. Remains of ''Anniealexandria'' are known only from a single fossil locality in the Bighorn Basin called Castle Gardens, but within the locality its fossils are common in the Willwood Formation, usually consisting of isolated jaw bones and vertebrae. ''Anniealexandria'' seems to have been a common component of a paleofauna that included fifteen other lizard species and existed in western North America during a period of global warming in the latest Paleocene and earliest Eocene.
