Wacky Days of September. THE DEVONIAN Climate and geography

The global climate during the Devonian period was surprisingly mild, with average ocean temperatures of "only" 80 to 85 degrees (compared to as high as 120 degrees during the preceding Ordovician and Silurian periods). The North and South Poles were only marginally cooler than the areas closer to the equator, and there were no ice caps; the only glaciers were to be found atop high mountain ranges. The smallish continents of Laurentia and Baltica merged to form Euramerica, while the giant Gondwana (which was destined to break apart millions of years later into Africa, South America, Antarctica and Australia) continued its slow southward drift.
