Fossil representation: Several individuals.

       Once considered a transitional form between archosaurs and lizards,‭ ‬palaeontologists are no longer as certain as they once were as to exactly how Prolacerta were related to these groups.‭ ‬One key observation is that the teeth are rooted deep and fused to the bones,‭ ‬and not loosely implanted like the teeth of known archosaurs.‭ ‬It’s probable that Prolacerta is closer to lizards,‭ ‬though at the time of writing it remains the only genus of the Prolacertidae.‭ ‬Prolacerta does have a small notch between the maxilla and premaxilla like some archosauriforms and rhynchosaurs,‭ ‬though it’s not certain if this is due to a familial relation or convergent evolution.
