Palaeotethys There is confusion over the relationship between Tethys (or Neotethys) and Palaeotethys. Some authors refer to the existence of a late Palaeozoic Palaeotethys which was a gulf at the margin of Panthalassa between the parts of Pangaea that were later to separate as Laurasia and Gondwanaland. This ocean, or large parts of it, were consumed in a Palaeocimmerian-Indosinian subduction zone. In the Jurassic a new ocean, or oceans, opened along the northern margin of Palaeotethys. This Jurassic-Cretaceous ocean has been called Neotethys or Tethys (sensu stricto).
