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.
