Early paleozoic era

MIT geologists have now reconstructed a timeline of the Earth's temperature during the early Paleozoic era, between 510 and 440 million years ago -- a pivotal period when animals became abundant ....

The Early Paleozoic Era Animals first appeared in ancient seas about 600 million years ago. Over the following several hundred million years animal groups diversified and went extinct in response to major global changes in climate, sea level, and mountain building. The unpublished material from China includes the collection of the macroalgal fossils from the Nantuo Formation. To accommodate the early Paleozoic fossils and to improve the description of macroalgal morphologies required that the list of morphological characters be expanded from 19 in Xiao and Dong (2006) to 30 in the current study.
