Gephyrosauridae is an extinct family of rhynchocephalians that lived in the Late Triassic and Early Jurassic.[1] They are generally considered to be rhynchocephalians that lie outside of Sphenodontia, but in some analyses they are recovered as more closely related to squamates than to sphenodontians.[3]
