The Cryptobranchoidea are a suborder of salamanders found in Asia, European Russia, and the United States. They are known as primitive salamanders , in contrast to Salamandroidea , the advanced salamanders .[1] It has two living subdivisions, Cryptobranchidae (Asian giant salamanders and hellbenders ), and Hynobiidae , commonly known as Asian salamanders.
Giant salamanders are obligate paedomorphs with partial metamorphosis,[2] but Asiatic salamander goes through a full metamorphosis. The only known exceptions are the Longdong stream salamander , which has been documented as facultatively neotenic, and the Ezo salamander , where a now assumed extinct population from Lake Kuttarush in Hokkaido had neotenic traits like gills in adults.[3]
The oldest members of the group are known from the Middle Jurassic (Bathonian ) aged Yanliao Biota of China.[4]
Taxonomy
[ edit ]
This suborder contains only two families at present. All other members are extinct and are only known as fossils.
† Chunerpeton Haifanggou Formation , China, Middle Jurassic (Bathonian ) (neotenic , has alternatively been recovered outside of Cryptobranchoidea)[5]
† Jeholotriton Haifanggou Formation, China, Middle Jurassic (Bathonian) (neotenic)
† Pangerpeton Haifanggou Formation, China, Middle Jurassic (Bathonian)
† Nesovtriton Bissekty Formation , Uzbekistan, Late Cretaceous (Turonian )
† Iridotriton Morrison Formation , United States, Late Jurassic (Tithonian )
† Kiyatriton Itat Formation , Russia, Middle Jurassic (Bathonian) Ilek Formation , Russia, Early Cretaceous (Barremian -Aptian ) (Presumed to be a cryptobranchoid)
† Laccotriton Fengshan fossil bed, China, Late Jurassic (Tithonian)
† Sinerpeton Fengshan fossil bed, China, Late Jurassic (Tithonian)
Cryptobranchidae (Late Cretaceous-Recent)
Panhynobia[4]
† Liaoxitriton Jiufotang Formation, China, Early Cretaceous (Aptian)
† Linglongtriton Tiaojishan Formation , China, Late Jurassic (Oxfordian )
† Neimengtriton Haifanggou Formation, China, Middle Jurassic (Bathonian)
† Regalerpeton Dabeigou Formation , China, Early Cretaceous (Hauterivian )
