Abrupt collapse of the tropical rainforest biome (Coal Forests) drove rapid diversification of Carboniferous tetrapods (amphibians and reptiles) in Euramerica. This finding is based on analysis of global and alpha diversity databases in a precise geologic context. From Visean to Moscovian time, both diversity measures steadily increased, but following rainforest collapse in earliest Kasimovian time (ca. 305 Ma), tetrapod extinction rate peaked, alpha diversity imploded, and endemism developed… Expand

Figures and Tables from this paper

Diversity change during the rise of tetrapods and the impact of the ‘Carboniferous rainforest collapse’
TLDR
The results suggest that the CRC was followed by increased global connectivity between communities, possibly reflecting both reduced barriers to dispersal and the diversification of amniotes. Expand
Carboniferous–Permian climate change constrained early land vertebrate radiations
TLDR
The results clarify the spatiotemporal expansion of land-living vertebrates and demonstrate that the reduction of tropical wetlands accommodated emerging dryland-adapted amniote faunas from a western Pangaean epicentre, suggesting that there was pervasive selection for such dryland adaptations across the crown tetrapod tree. Expand
Ancient islands acted as refugia and pumps for conifer diversity
TLDR
Biogeographical analyses corroborate that conifers experienced high continental extinctions, but survived on islands, and contribute to the world's conifer diversity as “island refugia” by maintaining early‐diverging lineages from continents during environmental changes on continents. Expand
Physical and environmental drivers of Paleozoic tetrapod dispersal across Pangaea
TLDR
The biogeography of Paleozoic tetrapods is analyzed and shifts in dispersal and vicariance associated with Carboniferous mountain formation and end-Guadalupian climate variability are found. Expand
The oldest parareptile and the early diversification of reptiles
TLDR
Stratigraphic calibration of the results indicates that parareptiles began their evolutionary radiation before the close of the Carboniferous Period, and that the diversity of end-Carboniferous reptiles is 80% greater than suggested by previous work. Expand
Modeled physiological mechanisms for observed changes in the late Paleozoic plant fossil record
Abstract Earth’s tropical forests repeatedly restructured on 105- to 107-year timescales during the Late Paleozoic Ice Age (340–280 Ma). Although it is established that these ancient plants respondedExpand
A living fossil tale of Pangaean biogeography
TLDR
A time-calibrated molecular phylogeny of Onychophora (velvet worms), an ancient and exclusively terrestrial panarthropod group distributed throughout former Pangaean landmasses, demonstrates that trans-oceanic dispersal does not need be invoked to explain contemporary distributions, and reveals that the early diversification of the group pre-dates the break-up of Pangaea.

The Oldest Caseid Synapsid from the Late Pennsylvanian of Kansas, and the Evolution of Herbivory in Terrestrial Vertebrates
TLDR
These results demonstrate for the first time that large caseid herbivores evolved from small, non-herbivorous caseids, and are mirrored by three other clades, documenting multiple, independent, but temporally staggered origins of herbivory and increase in body size among early terrestrial tetrapods, leading to patterns consistent with modern terrestrial ecosystem.

Abstract As significant indicators of deep-time palaeoclimate, a number of new palaeontological, pedological and geochemical characteristics are provided for the Chemnitz Fossil Lagerstatte to depictExpand

Recovery from the most profound mass extinction of all time
TLDR
The data showed that though there was an initial rise in cosmopolitanism after the extinction pulses, large drops subsequently occurred and, counter-intuitively, a surprisingly low level of cosmopolitanist was sustained through the Early and Middle Triassic. Expand
