Name: Chunerpeton ‭(‬Early creeper‭)‬.

Named By: Ke-Qin Gao‭ & ‬Neil H.‭ ‬Shubin‭ ‬-‭ ‬2003.
Classification: Chordata,‭ ‬Amphibia,‭ ‬Cryptobranchoidea.
Species: C.‭ ‬tianyiensis‭ (‬type‭)‬.
Diet: Carnivore/Insectivore.
Size: About‭ ‬18‭ ‬centimetres long.
Known locations: Mongolia‭ ‬-‭ ‬Jiulongshan Formation.
Time period: Usually credited as mid Jurassic,‭ ‬though the true age of the fossil deposits where the Chunerpeton type specimen comes from is in dispute at the time of writing.
Fossil representation: Complete and articulated skeleton with impressions of soft tissues.

       Chunerpeton was a key discovery as it represents the first appearance of a crown salamander in the fossil record.‭ ‬Unfortunately there has been a lot of debate and uncertainty about the true age of the fossil deposits that Chunerpeton comes from.‭ ‬Soft tissue impressions reveal that even in adult life Chunerpeton retained external gills,‭ ‬meaning that individuals of this genus spent most if not all of their time in the water.
