A Gerobatrachus hottoni (frogmander) a 290 million year old fossil has been found in Texas, the fossil which shows both frog and salamander traits has changed scientists opinions on the ancestry of amphibians. Scientists would now study the four distinct groups of leposondyls, temnospondyl, caecilians and amphibians.
Scientists can study the relationship between the frogamander and modern frogs and salamanders using phylogenetic analysis. The DNA from each species is sequenced and processed to find the amount of similarity between species. This information is presented visually in the form of a phylogenetic tree.
