Dragonflies with wings almost a metre across weave in and out of trees that tower 50 metres above you. On the ground, huge amphibians 5 metres long amble past – but watch your step, there are also metre-long millipedes and scorpions to avoid.” During this period oxygen levels were about 35% (21% today). The rest of the article is the usual academic squabbling, but the link between Oh-two levels and gigantism (and flight) seems quite possible. So, is there any textual evidence that there is also a higher than “normal” oxygen content in the Greenian atmosphere? Light headed visitors? Improved combustibility? Lots of raging fires? Possible adaptations to fire in plant life. Accelerated aging in animal life? Or is this suggestion just so much empty air? nastler Har du problemer med din hjemmecomputer?
