Anticline traps were discovered by geologists in the late nineteenth century, and are the most common structural traps in the world.

==Oil and Gas Trap==
:: [[Oil and gas traps|''main article'']]
An anticline formation can act as an [[oil and gas traps|oil and gas trap]] and is classified as a '''structural trap'''. Anticline traps beneath the Earth's surface will trap oil in one place. Oil that migrates into a reservoir rock that has been bent into an anticline shape will flow towards the crest of the arch. If there is a trap rock above the arch to seal the oil, it gets stuck in the anticline trap. The reservoir rock of the trap usually isn't completely filled with oil, rather it can also contain large amounts of salt [[water]].<ref>Petroleum Education. (September 19, 2015). ''Structural traps'' [Online].
