branchiosaurus
Branchiosaurus is the name of a problematic fossil fossil that lives from the end of the Carboniferous to the beginning of the Permian. This is probably the generic name of an animal that never actually existed. There is a problem with the status of this animal, which was found in thousands of fossils in Germany. There is no certainty as to whether the branchiosaur was truly a distinct species of amphibian, which, as a result of the evolutionary process of pedomorphics, has developed a larval appearance in mature individuals, or is a larval form of another species of amphibian. The appearance of these fossils is as follows: They are animals resembling Rhachitomi subspecies, but smaller, with shorter skulls and less ossified skeleton. Thanks to the behavior of soft tissues we know that they had 3 pairs of outer gills, from where their name came from. For some time it was considered true that branchiosaur was a new amphibian taxon for which a separate row of Phyllospondyls was produced.
