What was Panthalassa? Where was it?
At Everything Dinosaur, we get lots of enquiries and questions emailed to us. For example, we recently received an query about Panthalassa, the sender had heard the name but was not sure what this referred to, other than that it had something to do with ancient life. Panthalassa is the name of the huge, super-ocean that was created with the convergence of the world’s landmasses into a single block, known as Pangaea (sometimes also referred to as Pangea).
The Panthalassa Ocean
Panthalassa was formed in the Late Palaeozoic Era it persisted for much of the Mesozoic. It was sub-divided in the Late Triassic into Pacific and Atlantic regions as the geological process of rifting led to the formation of the Atlantic Ocean Basin.

An Enormous Body of Water
The Panthalassa Ocean at its largest size covered more than 70% of the entire planet’s surface. The term “Panthalassa” is derived from the Greek and means “all sea”. This enormous body of water was so vast, that if you had observed our planet from certain viewpoints in outer space, no trace of any land on planet “Earth” could be observed.
A spokesperson from Everything Dinosaur commented:
” We get contacted by all sorts of people asking all kinds of questions, students at university, pupils at school, parents contacting us on behalf of a curious child who has asked a question which they themselves have been unable to answer and we do our best to respond to all the queries that we receive. It might take a while for our team members to reply, but we do genuinely, try to help as many people as we can.”
Hopefully, the information we provided on Panthalassa will permit smooth sailing for the emailer when it comes to looking at prehistoric oceans from now on.
