The fossil record of fire first appears with the institution of the land-based flora in the Middle Ordovician period, 470 million yrs in the past.[twelve] These land crops contributed significant amounts of oxygen into the atmosphere if they unveiled it to be a waste solution. When this concentration rose higher than 13%, it permitted the potential for wildfire.[13] Wildfire is initial recorded from the Late Silurian fossil document, 420 million a long time in the past, by fossils of charred vegetation.[14][15] Other than a controversial gap during the Late Devonian, charcoal is present ever given that.[fifteen] The extent of atmospheric oxygen is intently correlated with the level of charcoal in the fossil record, Obviously pointing to oxygen as The real key Think about the prevalence of wildfire.
