Lungfish are best-known for retaining characteristics primitive within the [[Osteichthyes]], including the ability to breathe air, and structures primitive within [[Sarcopterygii]], including the presence of lobed fins with a well-developed internal skeleton. Today, they live only in [[Africa]], [[South America]], and [[Australia]]. While [[vicariance]] would suggest this represents an ancient distribution limited to the [[Mesozoic]] [[supercontinent]] [[Gondwana]], the [[fossil]] record suggests that advanced lungfish had a widespread freshwater distribution and that the current distribution of modern lungfish species reflects [[extinction]] of many lineages following the breakup of [[Pangaea]], [[Gondwana]], and [[Laurasia]].
