'''''Anakamacops''''' (meaning "similar to ''Kamacops''" in Greek) is a genus of dissorophid temnospondyl from the early Middle Permian of China. It is known from the right side of a snout that was described in 1999 from the Dashankou locality of the Xidagou Formation, which is within the city of Yumen. The type species was named ''A. petrolicus'' because Yumen is an oil-producing city (petrol).<ref name=LC99>{{cite journal |last=Li |first=J.-L. |author2=Cheng, Z.W. |year=1999 |title=New anthracosaur and temnospondyl amphibians from Gansu, China - the fifth report on Late Permian Dashankou lower tetrapod fauna |journal=Vertebrata PalAsiatica |volume=37 |issue=3 |pages=234–247 |url=http://www.ivpp.cas.cn/cbw/gjzdwxb/xbwzxz/200812/W020090813369418346132.pdf}}</ref> More substantial material, including a partial skull and partial mandibles, was described by Liu (2018).<ref>{{Cite journal|last=Liu|first=Jun|date=2018-11-05|title=Osteology of the large dissorophid temnospondyl Anakamacops petrolicus from the Guadalupian Dashankou Fauna of China|journal=Journal of Vertebrate Paleontology|volume=38|issue=5|language=en|article-number=e1513407|doi=10.1080/02724634.2018.1513407|issn=0272-4634}}</ref>

== Description == ''Anakamacops'' is most similar to ''Kamacops'', sharing features such as a choana widely separated from the interpterygoid vacuities and extensive exostosis ornamenting the skull roof. Both are large taxa; the most complete specimen of ''Anakamacops'' measures 26 cm in length despite lacking most of the snout. A number of potentially unique features were suggested based on the additional material described by Liu (2018), such as a relatively edentulous (lacking teeth) vomer and paired (rather than a single, unpaired) occipital ridge.
