Reworking the Cambrian Explosion Trilobite diversification during the Cambrian is thought to exemplify the explosion of animals and plants. New research suggests, however, that the trilobites diversified much earlier, thus calling into question the theory and possible dates of a biological big bang caused by tectonic movement. |

An African puzzle piece The time period from 32 to 24 million years ago has largely been a black hole for paleontologists studying East Africa's animals. Newly discovered large vertebrate fossils from Ethiopia, however, are providing evidence that not only was there a thriving and diverse population, but also that it continued long after. |

Fossil Bites Into Mammal Stereotypes Paleontologists uncovered the fossil of a large beaver-like mammal in China that lived on land and likely fished in lakes. The discovery could tear down previous stereotypes that mammals, while living alongside dinosaurs, could not develop extensive specialization. |
