Panthalassa (Greek, meaning 'all sea'), also known as the Panthalassic Ocean, was the vast global ocean that surrounded the supercontinent Pangaea, during the late Paleozoic and the early Mesozoic years. A Seattle-based screamo band formed in late 2010 and finished October 2011 after a little over a year of being together. The band broke up but went on to form different bands. They released a demo, a song for a compilation and a split with a band in Arizona called Broseph Smith.
