Paleozoic timeline
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 in a previously microbe-dominated world. In a study appearing today in the Proceedings of the National Academy of Sciences, the researchers chart ...Oceanic conditions and biological richness resulted in the greatest production of carbonate during the Paleozoic Era. The Devonian saw major evolutionary advancements by fishes with diversification and dominance in both marine and fresh water environments—the Devonian is also known as the "Age of Fishes.". Jawless fish and placoderms ...

By about 320 million years ago, early amniotes had diverged into two groups, called synapsids and sauropsids. Synapsids were amniotes that eventually gave rise to mammals.Sauropsids were amniotes that evolved into reptiles, dinosaurs, and birds. The two groups of amniotes differed in their skulls.The Paleozoic (IPA: /ˌpæli.əˈzoʊ.ɪk,-i.oʊ-, ˌpeɪ-/ PAL-ee-ə-ZOH-ik, -ee-oh-, PAY-; or Palaeozoic) Era is the first of three geological eras of the Phanerozoic Eon. Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Era.
