A recent study shows that marine oxygen levels were crucial to the evolution of early Paleozoic trilobite body size, suggesting that oxygen may have influenced the evolution of other animals' body ...
Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the ...
The temperature of a planet is linked with the diversity of life that it can support. MIT geologists have now reconstructed a timeline of the Earth's temperature during the early Paleozoic era, ...
