1 MAS 603 Geological Oceanography Proterozoic Evolution Isabella D’Ambra 18 February 2008 ± Meert & Liebermann (2007): reconstruction of the scenario where the Ediacaran- Cambrian transition happened; ± Stanley (1976): factors affecting the transition Ediacaran Cryogenian Tonian Stenian Ectasian Calymmian Statherian Orosirian Rhyacian Siderian Neoproterozoic era 1000-542 Ma Mesoproterozoic era 1600-1000 Ma Paleoproterozoic era 2500-1600 Ma Proterozoic eon Reconstruction of the scenario …but there are several hypotheses about the formation of this super- continent!!! From very simple ones (just the collision of pre-assembled pieces) to very complex ones, based on paleomagnetic studies (reconstruction of the latitude) and remains of the orogenetic events. Unfortunatelly, often just data from a single region are taken into account, giving a partial vision of the reconstruction. The existence of a previous super-continent (Rodinia or Paleopangea) seems well supported.
