EURAMERICA (also known as LAURUSSIA which is not to be confused with
Laurasia , the OLD RED CONTINENT or the OLD RED SANDSTONE CONTINENT)
was a minor supercontinent created in the
Devonian as the result of a
collision between the Laurentian ,
Baltica , and
Caledonian orogeny , 433 million years ago. In the Late
Carboniferous , tropical rainforests lay over the equator of
Euramerica. A major, abrupt change in vegetation occurred when the
climate aridified. The forest fragmented and the lycopsids which
dominated these wetlands thinned out, being replaced by opportunistic
ferns. There was also a great loss of amphibian diversity and
simultaneously the drier climate spurred the diversification of

Euramerica in the
Euramerica became a part of the major supercontinent
Pangaea in the
Permian . In the
Jurassic , when
Pangaea rifted into two continents ,
Euramerica was a part of Laurasia.
Laurasia split into the continents of North
Eurasia . The Laurentian craton became a part of North
Baltica became a part of
Eurasia , and
split between the two.
EVENTS BY PERIOD
* Carboniferous: Climate change devastated tropical rainforests,
fragmenting the forests into isolated 'islands' and causing the
extinction of many plant and animal species during the Carboniferous
Rainforest Collapse (CRC).
Euramerica became a part of the supercontinent Pangaea.
Pangaea rifted into
Laurasia split into the continents of North America
