A review of the paleontological literature shows that the early dates of appearance of Lissamphibia
recently inferred from molecular data do not favor an origin of extant amphibians from …

The origins of the extant amphibians (frogs, salamanders, caecilians) remain controversial
after over a century of debate. Three groups of hypotheses persist in the current literature: the “…

The largest published phylogenetic analysis of early limbed vertebrates (Ruta M, Coates MI.
2007. Journal of Systematic Palaeontology 5:69–122) recovered, for example, …

We present an update of our time-calibrated supertree of extant and extinct lissamphibians (Marjanović
D, Laurin M. 2007. Fossils, molecules, divergence times, and the origin of …

The origin of frogs, salamanders and caecilians is controversial. McGowan published an
original hypothesis on lissamphibian origins in 2002 (McGowan, 2002, Zoological Journal of …

‘Microsaurs’ are traditionally considered to be lepospondyl non‐amniotes, but recent analyses
have recovered a subset of ‘microsaurs’, the fossorially adapted Recumbirostra, within …

To evaluate stratigraphic evidence for the time of origin of the clade of extant amphibians (Lissamphibia),
we attempt to establish a confidence interval on the lower bound of the …

Paleozoic varanopid synapsids and diapsids, rare members of the terrestrial fossil
assemblages, are not closely related to each other but appear to have acquired a number of …

The origin of extant amphibians has been studied using several sources of data and methods,
including phylogenetic analyses of morphological data, molecular dating, stratigraphic …
