Many modern amphibians have biphasic life cycles with aquatic larvae and terrestrial adults.
The central questions are how and when this complicated ontogeny was established, and …

Live‐bearing has evolved in all three orders of amphibians—frogs, salamanders, and
caecilians. Developing young may be either yolk dependent, or maternal nutrients may be …

Salamanders are an important group of living amphibians and model organisms for
understanding locomotion, development, regeneration, feeding, and toxicity in tetrapods …

The relationships of frogs, salamanders, and caecilians (Gymnophiona) with one another
and with the vast assemblage of Palaeozoic amphibians remain highly contentious …

The origin of the Lissamphibia is the subject of continuing debate, and there is no current
consensus. Albeit often considered a different problem, the intrarelationships of crown …

The scant fossil record of caecilians has obscured the origin and evolution of this
lissamphibian group. Eocaecilia micropodia from the Lower Jurassic of North America …

ABSTRACT Eocaecilia micropodia, an Early Jurassic caecilian from the Kayenta Formation
of northeastern Arizona, is structurally comparable to Recent gymnophionans in numerous …

Abstract The Albanerpetontidae are Middle Jurassic-Miocene amphibians that have
variously been regarded as caudates (salamanders), a clade distinct from caudates, or …

Of living amphibian groups, the limbless burrowing caecilians are amongst the most highly
specialised, but are the least known. Their fossil record is extremely poor, leaving …

The Gymnophiona are the least well known amphibian order, an unfortunate situation
because these animals can clarify many aspects of amphibian natural history, vertebrate …
