   • 1871, St. George Mivart, On the Genesis of Species‎:

     Pleurodont lizards are such as have the teeth attached by their sides {148} to the inner surface of the jaw, in contradistinction to acrodont lizards, which have the bases of their teeth anchylosed to the summit of the margin of the jaw.

     The known skeletal remains of Longisquama lack any other diagnostic archosaurian characters [the furcula mentioned by Jones et al. consists of paired clavicles, as Sharov originally noted], but they exhibit two features, acrodont teeth and an interclavicle ( 3 ), that are typical of lepidosaurs.
