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 …

The question of what the ancient life cycle of tetrapods was like forms a key component in
understanding the origin of land vertebrates. The existence of distinct larval forms, as …

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

As a single stratigraphic source and site of high-fidelity vertebrate trackways and superbly
preserved skeletons, the Lower Permian Tambach Formation, lowermost unit of the Upper …

Georgenthalia clavinasica, a new genus and species of amphibamid dissorophoid
temnospondyl, is represented by a small, complete, postmetamorphic skull from the Lower …

Here we describe the postcranial skeleton and present the first full-body reconstruction of
the early tetrapod Whatcheeria deltae from the Viséan of Iowa. The skeletal proportions …

We review the cranial morphology of the Late Carboniferous terrestrial tetrapod
Gephyrostegus bohemicus from the coal deposits of the Nýřany Basin in the Czech …

Lower Permian strata of the Boskovice Basin in the Czech Republic have yielded hundreds
of largely complete seymouriamorph individuals, some of which are exceptionally preserved …

The diversity and evolution of the temporal skull region is a classical text book example of
comparative anatomy. In the earliest land vertebrates this region was, in most cases …

One of the major questions in evolutionary vertebrate morphology is the origin and meaning
of temporal skull openings in land vertebrates. Partly or fully surrounded by bones, one, two …
