Permian Mass Extinction

Coal-Burning Contributed to End-Permian Mass Extinction An international team of geologists has found the first direct evidence that volcanic eruptions in the southern part of the Siberian Traps region 252 million years ago burned large volumes of coal and vegetation. Elkins-Tanton et al demonstrate that the volume and composition of …

Carboniferous Period Fish

Paleontologists Redescribe Enigmatic Period Fish A team of U.S. paleontologists has redescribed the morphology of a long-snouted ray-finned fish called Tanyrhinichthys mcallisteri and created a more complete and accurate reconstruction of the fish as a living animal. Tanyrhinichthys mcallisteri was most likely a bottom-cruising predator similar in general ecomorphology to …
