Pangaea believed to be the main cause of the shrinking of lysocline areas. The third cause of this extinction event that can be attributed to northern Pangaea is the beginnings of anoxic ocean environments, or oceans with very low oxygen concentrations. The mix of anoxic oceans and ocean acidification due to metal loading led to increasingly acidic oceans, which ultimately led to the extinction of benthic species. Pangaea Pangaea or Pangea () was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and it began to break
Gondwana Link this further supports the intentions of the Gondwana Link vision. The Gondwana Link project began in 2002 as an informal coalition with the purchase of Chereninup Creek Reserve and other activities. It was not until 2012 that an incorporated body was formed with the establishment of Gondwana Link Inc. Operational areas are made up of eight major zones.
