Southern Topeyed Lampreys
Mordacia
Mordacia is a genus of lamprey, the sole genus of the family Mordaciidae, also known as the southern topeyed lampreys.
The family Mordaciidae is most closely related to the lamprey family Geotriidae, which has a similar Gondwanan distribution, and both families diverged during the Early Cretaceous. Together, their common ancestor diverged from the Petromyzontidae during the Middle Jurassic.
