Could a human survive in the Devonian period?
Note: The Devonian period lasted from about 420 million years ago until about 360 million years ago. Short version: They'd have to rely heavily on fishing to survive. If they got to start out with modern fishing boats, harpoons, and durable nets, they'd do well. If not, it would be much more difficult.Sep 19, 2013
Was there oxygen in the Devonian period?
Previous estimates suggested that during the Early and Late Devonian, oxygen levels were somewhat lower than the present 21%, dropping slightly from about 19% to about 17% by the middle of the Frasnian, then rising steadily thoughout the Mississippian to reach about 33% by the end of that period (Fig.Aug 13, 2007
Could humans breathe in the Devonian Period?
The climate was survivable. The atmosphere had about 75 percent of the oxygen it does today; but there's a city with 55 percent of the oxygen at sea level today, so that's well within what we can manage. The temperature wasn't too bad either, around 86 Fahrenheit.Sep 19, 2013

What dangers were in the Devonian Period?
The Devonian period ends with a cataclysmic extinction event, particularly devastating to warm-water marine communities. Nearly 70-80 percent of marine invertebrate species are wiped out over two extinction pulses. Oxygen nears present-day levels of 21 percent by volume of the atmosphere.
What was the atmosphere like during the Devonian period?
During most of the Devonian Period, the climate was relatively mild and the continent of Euramerica, which straddled the equator at the time, set the scene for the spread of tropical and equatorial forests.
Could a human survive in the Carboniferous?
The earliest period in which humans could live as a land-based rather than a coastal species would be the Devonian (419-358 MYA) or the Carboniferous (358-298 MYA) eras, during which land-based life spread out and became established.Nov 16, 2014

What was Earth's climate like during the Devonian extinction?
In the Devonian period, Waters explained, the world was experiencing super greenhouse climate conditions. This means that it was very warm, there probably were no ice caps, there was a lot carbon dioxide in the atmosphere (with estimates of 4,000 parts per million).Dec 13, 2013

What caused the climate in the Devonian Period?
Sea levels were exceptionally high during the Devonian, giving a widespread relatively warm and equable climate for most of the Period.Oct 29, 2012
