Primary description of more than thirty Balanerpeton skeletons from the East Kirkton succession; temnospondyl placement is kept separate from competing lissamphibian-origin hypotheses.
Claim ledger
fossil-range · mediumThe broad Amphibia navigation envelope uses the East Kirkton Balanerpeton sample and its 341 ± 3 Ma detrital-zircon maximum depositional-age constraint as the older evidence anchor and living amphibians at 0 Ma as the younger edge; the MDA is not a direct fossil date, global FAD, crown-Lissamphibia age or direct-ancestor claim.
