Scientists believe a natural event in the Cretaceous shows evidence that natural phenomena could be the trigger fires. To reach that conclusion, researchers analyzed sediment charcoal (charcoal) in the geological record. Then, build a global database to find out how often fires occur in a large scale.
Scientists have found several factors that cause forest fires, including the greenhouse effect that occurred during the Cretaceous period. This indicates, when the average temperature is much higher than in modern times.
Other conditions such as lightning strikes also have great potential to trigger a forest fire. In addition, a team of scientists believe that the phenomena of the atmosphere with high oxygen concentration also has a great chance of the fire.
"This is a (factor) why fires are so extensive. In that period, not like today, plants with high humidity can potentially burn," said researchers from the Field Museum and author of the report, Ian Glasspool.
"Charcoal is the residue from the burning plant and easily preserved in the fossil record. Just a little attention to the impact of fires on the environment, which not only destroy vegetation, but can also cause erosion and flooding due to forest fires," said Andrew C. Scott of Royal Holloway University of London.
Researchers Reveal Forest Fires in the Cretaceous Period
Scientists recently revealed naturally occurring fires in the Cretaceous or Cretaceous period. Investigation was conducted by experts from the Royal Holloway University of London and The Field Museum of Natural History in Chicago, United States.
Softpedia, extensive forest fires in the Cretaceous period approximately 65 million years ago. Dinosaur when it should avoid the spread of forest fires in order to survive.
