The '''Decaturville crater''', also referred to as the '''Decaturville Dome''', is an [impact crater](/source/impact_crater) near the town of [Decaturville](/source/Decaturville%2C_Missouri), [Missouri](/source/Missouri), United States.

==Description==
The crater is one of the [38th parallel structures](/source/38th_parallel_structures), a series of circular geophysical features stretching across the central United States which have been hypothesized to be the remnants of an ancient serial impact event.

The Decaturville crater is {{convert|6|km|mi}} in diameter and is estimated to be less than 300 million years old (dating to the [Permian](/source/Permian) or younger). The crater is exposed at the surface.<ref>{{cite Earth Impact DB | name = Decaturville | accessdate = 2009-08-13}}</ref> The effect that the impact had on the surrounding bedrock can be seen in a roadcut that runs along [Highway 5](/source/Missouri_Route_5) about 16 miles north of [Lebanon](/source/Lebanon%2C_Missouri).

The crater was first described and mapped in detail by T. W. Offield and H. A. Pohn under [NASA](/source/NASA) funding in the 1970s. Their work was reported in a 1979 [U.S. Geological Survey](/source/U.S._Geological_Survey) Professional Paper that provides the most detailed description to date.<ref>{{cite journal|last=Offield|first=T.
