At the end of the last glacial period, while the rock was still depressed, the Saint Lawrence and Ottawa River valleys, as well as modern Lake Champlain, at that time Lake Vermont, were below sea level and flooded with rising worldwide sea levels, once the ice no longer prevented the ocean from ...
In the same period (between 120 and 105 Ma) there was more volcanism in eastern Australia, leading to uplift creating the Tasman Sea to the southeast and the Coral Sea to the north. The earliest land plants preserved in Australia occur in deposits from the Upper Silurian and the Lower Devonian in marine sediments in Victoria, named the ...
