What is "amphibamidae"

Amphibamidae is an extinct family of dissorophoid euskelian temnospondyls. The earliest amphibamids, such as Amphibamus, are known from Late Carboniferous strata in the United States and the Czech Republic, while the last known amphibamid, Micropholis, is known from the Early Triassic Karoo Basin of South Africa. According to some phylogenetic studies, modern amphibians, including frogs, salamanders, and caecilians, may have descended from a common ancestor that was an amphibamid.
