Abstract

Salamanders are the only tetrapod that can fully regenerate their limbs and tail, a capacity that might be linked to their unique preaxial mode of limb development; here, data from fossils reveal the existence of preaxial polarity in various amphibians from the Carboniferous and Permian periods, suggesting that salamander-like regeneration is an ancient feature of tetrapods that was subsequently lost at least once in the lineage leading to amniotes.
