A chemical utilized by crops to defend their flowers, oleanane, has long been detected in fossil plants that aged, which include gigantopterids, which developed at that time and bear many of the traits of modern, flowering vegetation, although they are not identified to get flowering vegetation them selves, due to the fact only their stems and prickles have been found preserved intimately; one of the earliest samples of petrification.
