The question of how tetrapod limbs evolved from fins is one of the great puzzles of
evolutionary biology. While palaeontologists, developmental biologists, and geneticists have …

There is an unexplained terrestrial mass extinction at the Devonian-Carboniferous boundary
(359 million years ago). The discovery in east Greenland of malformed land plant spores …

The acquisition of terrestrial, limb-based locomotion during tetrapod evolution has remained
a subject of debate for more than a century,. Our current understanding of the locomotor …

Recent efforts have led to the development of extremely sophisticated methods for
incorporating tree-wide data and accommodating uncertainty when estimating the temporal …

Current hypotheses of early tetrapod evolution posit close ecological and biogeographic ties
to the extensive coal-producing wetlands of the Carboniferous palaeoequator with rapid …

The invasion of the land was a complex, protracted process, punctuated by mass extinctions,
that involved multiple routes from marine environments. We integrate paleobiology …

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

The Carboniferous and early Permian were critical intervals in the diversification of early four-
limbed vertebrates (tetrapods), yet the major patterns of diversity and biogeography during …

The middle–late Cambrian is a crucial transition interval linking the Cambrian Explosion
(CE) and the Great Ordovician Biodiversification Event (GOBE). Previous studies have …

Concurrent gaps in the Late Devonian/Mississippian fossil records of insects and tetrapods
(ie Romer's Gap) have been attributed to physiological suppression by low atmospheric p …
