Colour photograph of a black rock
Charred plant: probably from Lepidodendron. Upper Carboniferous. Clifton, New Brunswick. Collector: R.F. Miller and J. McGovern, 1997. New Brunswick Museum (NBMG 12161). Image width 10 cm. Levels of atmospheric oxygen were higher than today, possibly as much as 35%, instead of the current 21%. Wildfires may have been a more common feature of the forests. Charcoal layers can be seen in many Upper Carboniferous rocks.
