Stranded in hostile past eras

They are stranded in Earth's most hostile past environments: the Early Triassic desert, the humid Carboniferous jungle teeming with giant insects, and the fungal-dominated Early Devonian. The time machine eventually restarts, leaving their ultimate fate uncertain.

  • ๐Ÿ„ The Early Triassic was a "Hothouse Earth" 250 million years ago, with 3-5x more CO2, 50ยฐC air, and no ice.
  • ๐Ÿ› The Carboniferous period (320 million years ago) had 60% higher oxygen, leading to cat-sized insects like Megarachne and meter-wide griffinflies.
  • ๐Ÿ„ The Early Devonian (400 million years ago) featured 8-meter-tall fungal Prototaxites and low oxygen (15%).
  • โš™๏ธ The time machine is unreliable, jumping between eras rather than allowing controlled travel.
