Karaurus
Karaurus (meaning "head-tail") is an extinct genus of stem-group salamander from the Middle to Late Jurassic (Callovian–Kimmeridgian) Karabastau Formation of Kazakhstan. It is one of the oldest salamanders known. "Karaurus" was about long, and very similar anatomically to modern salamanders. It probably swam through fresh water feeding on aquatic snails, worms, crustaceans and insects. "Karaurus" is thought to form a clade with "Kokartus" from the Bathonian of Kyrgyzstan, together forming the Karauridae, as the sister group to crown salamanders.
