Wild Fires, Charred Flowers and the Fossil Record
One of the main types of fossil used to understand the first flowering plants (angiosperms) are charred flowers. These charcoals were produced in ancient wildfires, and they provide some evidence for the types of plants that grew millions of years ago. However, when fires burn they not only produce charcoal, but they also destroy it.
This is important because if scientists are trying to use charred flowers to understand the diversity of the earliest angiosperms then they also need to consider that some flowers may have been turned to ash in these ancient fires and not preserved as charcoal at all.
