It tells us that the continents were in the arctic.
It could not survive in salt water, could not live in oceans
It ate fish.

Tropic Plant fossils found in Antartica
Earthquakes in Ring of Fire
Mesosaurus fossils found in South American & Africa
Continents fit like puzzle pieces

Subduction
Convection
Radiation
Conduction
